Cpu burn-in

I have just finished assembling a new computer. In fact, it is the first one which I put together. I am looking for recommendations on a cpu burn-in program. There doesn't appear to be one in AUR or the standard repositories.

Hmmm if that's the case
#!/bin/bash
while true; do
dmesg > /dev/null
done
that should loop sufficiently fast enough, and do enough operations to shoot CPU usage to 90-100%
Just do "sleep 600 && killall oddscript" so it runs for 10 minutes....

Cpu burn-in question...

Hi all, I decided to try out cpu burn-in to see how high my load temps get opposed to using seti@home. What are your opinions on disabling error checking? also, I notice in speedfan that it only loads one of my logical processors. Is it doing it's job to it's potential?

It looks like your burn in program is not multitasking, so it really isn't a full workout.

970A-G45 CPU BURNING UNDER BIOS

My CPU temp is jumping 60-65C from 35C under ONLY BIOS. Im using Win7 when system not on load temp around 35-40C, underload (playing BF3 multiplayer with high settings) 45-50C so there is no heat issues on normal use everything fine also my room has some heat issiues around 22-25C. I just updated bios from 1.3 to 1.4 than finally 1.5 2-3 days ago and i tried to check anything new on bios than i saw CPU temp getting higher so fast around 60C from 35C fan makes kinda tornada there with 5k rpm and disturbing noise after that i cleared fan put little Sunbeam Tuniq TX-2 but still same problem in bios. I didn't do any overclock i didn't use OC Genie 2 too. Everything on default or auto in bios. Also my core voltage in bios around 1.43 - 1.68 its not stable i read other posts about that people talking about Cool and Quiet option in bios but i couldnt find it Is there any solution?
So here is my system specs:
CPU: AMD Phenom II X4 3.4 Ghz with original heat sink fan
MOBO: MSI 970A-G45 (bios 1.5)
RAM: GEIL Enhance Corsa 8 GB DDR3 1600 Dual Kit
GPU: MSI R6850 Cyclone 1GB DDR5 PE/OC

badboy2k i agree with you, results are same with Akasa Venom in windows overload with prime96 max 53C in bios 53C too and i want to ask that that cooler is so heavy do you think it has some potential to hurt mainboard in future?
as long as its mounted properly with a good back plate then no it shouldnt damage the board at all! motherboards with a decent weight distrabuting plate at the back wont be damaged as there multi layer/ plyed boards and as such very strong typically capable of supporting a weight of 40-70 Pounds per square inch around the cpu socket! anyway manufacturers of aftermarket coolers know what the maximum mounting weight is and make a cooler below that limit!

PC WONT BOOT....CPU BURNING UP

I have just purchased a K7N420 PRO motherboard. with the following
300w atx power supply.
Athlon XP 1800 266 DDR processor.
512 DDR RAM
5000RPM FAN
I decided to build my own computer and buy all the components separately. I installed the motherboard and all relevant parts. I attached a 5000rpm heatsink fan to the processor and made sure it was installed properly.
I also installed the D-bracket to insure I knew if I had any problems.
As soon as I turned the computer on all four leds lit up and nothing was shown on the monitor. It didn't work.
As the manual told me that the problem was the processor I turned everything off and detached the processor to find it has burnt itself out and was broken.
I decided to buy another one and a more powerful fan but to my suprise the same thing happened.
Is there any reason why the motherboard is 'frazzling' my processors.

The monitor remained black all the time and never even came on.
so is the CPU cracked? or not? im geting confused...
if its not... 4 red LED's dosnt mean the CPU is dead.. thare are many other things that can give you 4Red's

Pls advise PSU and CPU temp.

At last i have decided to go for Herolchi HEC 525w Dual Fan Ball Bearing ATX Power Supply, after installing the New PSU my CPU Temperature go up by 3 degree...not sure whether all the RAIL will effect the temperature ?
Pls take a look on my comparison : -
Old PSU Young-Year 480W (Taiwan)
Vcore : 1.48 ~ 1.50
+ 3.3v : 3.10 ~ 3.17
+ 5v : 5.08 (no changes)
+ 12v : 11.64 ~ 12.00
System : 35 ~ 38 degree
CPU idle : 40 degree
full load : 57 degree (Prime95 & CPU burn-In)
New HEC 525W (recommded my Intel and AMP)
Vcore : 1.47 ~ 1.50
+ 3.3v : 3.30 ~ 3.36
+ 5v : 4.97 ~ 5.0
+ 12v : 11.76 ~ 11.88 (never hit to 12.00)
System : 36 ~ 39 degree
CPU idle : 43 degree
full load : 60 degree (Prime 95 & CPU burn-in)
Understand that all the variance for the above RAIL are within Spec +_ 5%
Hi All, pls help to post all your RAIL lowest/highest for +3.3v, +5.0v and +12v..as well as system/CPU temperature, thanks....

I would not worry about the extra 3 Deg. C that the CPU is now running at. 60C under full load is well withen normal specs. ..As for the new PSU, I am not familiar with that brand...If you could ,would you POST the AMPS on the RAILS, as that is more important than the Volts...You can find the AMP specs. on the side sticker of the PSU..ie..+12V=?A, +3.3V=?A, +5.0V=?A...THANX..Sean REILLY875

Burn Issue: Certain Chars causing trouble w/burn

Recently I've noticed some "!" in cd/dvd's (mp3) that I've burned... Songs with the characters ? " / don't burn to the disc... (there may be other chars but these were the one's I noticed on the last disc I burned) I can remove those chars and the songs burn fine... Yeah these are kinda like 'OS special characters' but my buddy's cpu burns these files fine... Any insight on this matter?
thanks in advance...

P67A-C43 (B3) boot loop after cpu cooler replacement

Hi,
I built my system in September last year and it has worked fine until now.
my components are:
CPU: Intel Core i5-2500K 3,3GHz
RAM: Corsair XMS3 DDR3 PC3-1333MHz 4x2GB
GPU: Gigabyte GV-N460OC-1GI
PSU: Corsair CX600
And a old random HDD
I was inside the bios the other day an saw that the CPU temp was way to high (i believe it was 97c).
So i decided to decided to do a spring cleaning and replace the CPU cooler from the default to a new "Antec Kuhler H2O 620" that i bought a while ago and never installed. So i unplugged the computer and vacuumed the worst of the dust out of my case (A Antec Dark Fleet DF-85) and then i installed the new cooler.
When i pressed the power the computer powers on for about 4 seconds and (all 4 CPU led:s turns on) and then it reboots.
So I started trouble shooting:
I checked all cables.
I unplugged all sys fans to see if the new cooler was drawing to much power.
I removed my HDD and GPU.
Then i tried a lot of different ram switching and removing including removing all ram.
I reset the cmos
I put the old cooler back in.
Finally i took the bored out of the case and put it on a table and tried to boot i there.
And i have not had any changes in behavior from any of the different changes.
My theory is that ether the mother board is broken or that the CPU burned.
So what do I do now? is there a way to test if the motherboard is broken whiteout a CPU or is there a way to see if my CPU is broken?

Hi
Check in the mobo socket if there are no broken or damaged pins and some thermal paste is conductive might be some leftovers in the cpu.
I can not find any damage to board. I tock out the cpu and there only past on the cpu heat sink and the socket looks fine.
the new cooler had already past on it so i tock of the old from the cpu and used used the already existing on the cooler.

Why is my laptop running high cpu after i render 3DS Max For a month and what should i do?

I have been trying to run my long 3ds max finals. I have 2 fans blowing my Macbook Pro. The Laptop fan and a regular fan blowing my laptop. after a month of finish rendering. my cpu sky rockets and i i have try scan for malware, virus, spy ware and worms, which didn't do nothing, i also check for defragment. Nothing works. the 3ds max was running on bootcamp windows 7. When i render in 3ds max the cpu hits 100% non stop. should i go to apple store and to get it check and would it cost alot to get it fix? Thank you for anyone answering my question.

The firmware controlling the fans is predictive depending upon what sort of software and it's CPU demands, you have been running.
For instance, you say your 3D program maxes out the CPU, well the computer now knows whenever you launch this program it needs to crank the fans up, even if you don't use much CPU at first, in order to catch a sudden demand in CPU needs and not let the CPU burn up.
Don't know if there is a remedy for this unless not to use the 3D rendering software, or use on a machine with more processing cores and better cooling, like a MacPro.

K9N Platinum SLI - Powering up the PCIe cards

Hey everyone,
I've got a K9N Platinum SLI board. This board has a power supply input point called PWR2, which according to the documentation is used to provide power to stable the operation of graphics cards. My graphic card is BFG nVidia 9750 GT. This card has the PCI-Express external power plug in the back, and my power supply has a dedicated (red) connector for this purpose, which I have attached properly.
The PWR2 is currently connected also, into one of the black 12V connectors. Otherwise, everything is running fine and smooth, but I am sometimes (once a day or so) experiencing random shutdowns during intense gaming (playing LotRO). Stress testing does not cause a shutdown: I've ran 3D Mark 2007 straight for 8-9 hours, while having a CPU Burner application toast the CPU at the same time. But no problems whatsoever. No other games exhibit this problem either.
Since I am providing dedicated power through the extra connector at the back of the card, should I leave the PWR2 connector unplugged ? Is there a chance that using these two connectors at the same time causes the 12V rail to overload, and the PSU shuts down to protect itself ? When this shut down occurs, the power LED is left blinking and I need to plug out the wall socket and wait for several minutes before the blinking stops and it starts up again.
My computer has an Enermax Liberty 620W power supply, and AMD Athlon X2 4600+ CPU. So there should be enough juice, at least. I've tried the tips and tricks suggested here. Using USB-connected Keyboard and Mouse does not correct the issue. I've also verified that this is not an overheating issue. My CPU is cooled by a Scythe Ninja tower heatsink and two 12 cm fans. It is possible that the northbride is heating up (it burns the finger on touch when under load), but from the Web, I've understood that the stock passive heatsink should be enough, and that the NB chip can take rather extreme temperatures.
* UPDATE *
Plugged the PWR2 connector out from the MB, and update the BIOS to 1.10. It's working as usual, but haven't ran any games yet. Heavy gaming usually reproduces the issue, so I'll write more when I know more.

Updated information on the case.
I've been running 2 days now with the PWR2 unplugged. I have had zero problems with shutdowns since. The only problem I now have is that the USB keyboard and mouse refuse to work in Windows XP after an initial bootup from powered down state. I have to unplug and replug them at the login screen in order to get them work again.
So, I decided to do a final sanity check, and replugged the PWR2, then went gaming. After 2 hours of playing, my computer shutted down for the first time. Plugging in the cable did not solve the USB problem either.
As of this day, I'm leaving it unplugged. It seems like an irrelevant connector, which just causes problems.
** Update **
After following Bosskiller's instructions on another thread about using the "Clear CMOS" button and then reconfiguring BIOS from scratch, the cold boot USB issues were solved. The USB devices now work straight after a cold boot, with no need to replug them.
I recommend that the PWR2 -connector info is added to the list of known problems in the sticky thread. If you have a GPU card which takes its power from a dedicated rail (and your PSU has a dedicated connector for this purpose), then leaving the PWR2 -connector unplugged might resolve your shutdown issues, like it solved mine.
After all, according to the manual, this connector is used to give more voltage to the PCI and PCIe busses, and some PCI/PCIe cards might not like this idea at all. There is a reason why these cards have an additional power plug on them...

"Save As" and "Open" file dialog windows very slow to appear...

I have a home network with 4 PCs, three using XP/3 and 1 using Win7. Until recently, I had the three XP boxes in one workgroup (not homegroup) and the Win7 box in a different workgroup. Everything was running fine. I got anal and decided
to rename some of the boxes and put them all in one workgroup, the one that the Win7 box is in.
Immediately after I did all that, I noticed that every time I did a "save as" file function on the Win7 box, no matter the application, the dialog window took much longer to appear - sometimes almost 10 seconds. This is not the case on the XP
boxes.
Following a suggestion I got on the Microsoft Answers Forum, I removed all the shares on my network and even removed the 3 XP boxes from the network, and I turned off Network Discovery. The problem persisted. Only when I disabled my LAN
connection did the dialog windows appear instantly, as they had done before. I have now restored the original configuration, but the "save as" dialog window continues to come up very slowly on the Win7 box.
Any thoughts, clues or suggestions as to how to fix this non-critical but very irritating problem would be greatly appreciated...

I've hit a similar problem since (or at least exaserbated since) changing to a new ISP service (BT Total Broadband) which included a wifi router upgrade. LAN has a stable Win XP SP3 fully updated, a W7 also fully updated (I love Office) and a previously
stable Zyxel router. Then this occasional problem: File -> Save As from any application stops dead for up to a few minutes, no CPU burn so waiting on interupt or external event. Patience, then it works.
So I'm guessing a confused IP table somewhere. I'm off to play with using fixed IP addresses and lease expiries in the LAN part of the new router's config to see if that makes it easier for XP to handle closed connections.
And isn't there a "not persistent" option somewhere ...
But I don't networked drives, I use shortcuts with network addresses.
More anon after some exploration.

Using Event Structures with Array of Clusters

Using LabVIEW 8.5
Hi all,
I'm trying to convert an existing application to one that can be used
through a touch screen. I updated the UI and added an event structure
to listen for mouse ups on controls that require a HMI keyboard or
numpad to show up. Although I've been programming for a while, I'm new
to LabVIEW and am struggling with a problem:
Is there any way to have an event case listen to an event within
arrays? I've seen a few examples on the forums, but they all start with
breaking up the arrays into individual variables. Using the variables,
they build arrays. This seems pretty tedious, and I'm pretty sure I
can't apply it to one of my arrays. Essentially, I just want to know
which cluster in which array the user has clicked on, so I can open the
HMI keyboard or numpad and send the text to that cluster. In my watered down app (Array of Clusters.vi), I've put 3 arrays of clusters and a few stand-alone controls to give you guys an idea of what I'm taking about.
BTW, I'm using the HMI Keyboard and Numpad built by the Beta Community (http://decibel.ni.com/content/docs/DOC-1062) and modified it to add a "Clear" button to the keyboard and numpad. Please let me know if I implemented this in the best way.
Thanks for the help,
Kunal

You probably can adapt some of it for the arrays on the right. If the array can be scrolled, you also need to account for the "indexvals" offset.
The Layers controls is easiest, because you only show one element. Just read the "index vals" property to get the array element and parse the coordinates to get the cluster element.
btw: the small while loop on the right serves no purpose at all and acts just as a CPU burner. You can delete it without any change in functionality. Is there anything else to it?

Overclocking Guide

Overclocking Guide

Neither MSI nor any of this thread’s authors shall be liable for any errors or delays in the content or be held responsible for any damage caused by modifying or overclocking your computer. Manufacturers may or may not honor the warranty on any overclocked or modified computer components. Perform any modifications to your systems at your own risk.
Why Overclock?
Today, overclocking is not any secret. It has become more popular and almost become an addiction to some people. The definition of Overclocking is simple: it means operating an Integrated Circuit beyond its specified clock speed.
But why overclock? Some people say to get more out for the same money. “It’s there; why not get more out of it?” However, the best business reason for overclocking is that it can make “out of date” equipments useful again. If the equipment is already out of warranty, the risk is very limited. (I personally suggest any beginners to overclock any out of date PC first just to have some first time experience.)
Know more about the Central Processing Unit (CPU)
Processor speed is based on two factors. The first is the interface between the motherboard and the front side bus (FSB). From http://en.wikipedia.org/wiki/Main_Page (Wikipedia, the free encyclopedia), FSB is the speed at which the CPU communicates with RAM (memory). Many system components - including the PCI and AGP buses usually run at speeds derived from the frontside bus' speed. In general, a faster frontside bus means higher processing speeds and a faster computer. The other factor controlling a CPU's speed is the clock multiplier. It defines the ratio of processor speed to the FSB.
The FSB on new processors ranges from 400 MHz to 800 MHz. These are not straight clock speeds but instead they are quad-clocked speeds. These processors actually transmit data four times per clock cycle, for example, 800 MHz FSB is actually four times the 200MHz clock (200 MHz x 4 = 800 MHz).
The core speed of the CPU is the product of the front side bus clock and the multiplier. A processor running at 3600MHz (i.e. 3.6 GHz) might be having 800 MHz FSB, this means there is a clock multiplier setting of 4, and thus the CPU is set to run at 4 times the MHz speed of the front side bus.
But we said earlier that they are quad-clocked speeds, so 3600 MHz actually came from 18 times 200 MHz (200 MHz x 18 = 3600 MHz).
Please note that not all processors have quad-clocked speed FSB. For example, the Intel Pentium 4 (Northwood core) has quad-clocked speed FSB. But for example, the Intel Pentium III, AMD Athlon XP and AMD Duron have dual-clocked speed FSB only.
To know more, please read:
http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2178
Let’s lock the clock multiplier
Few years ago, you could overclock processors by choosing a higher multiplier. This option was eliminated in order to fight CPU remarking. Counterfeit processors have regularly appeared in the market, as the CPU speed was only defined by your setting. Nowadays, the restriction to only one multiplier is both of overclocking and counterfeit prevention.
As you can see, the only way of overclocking today is choosing a higher front side bus clock and the offer of small increments e.g. 1MHz in today's motherboards give us a great advantage in overclocking.
However, some CPUs nowadays are still unlocked, for example, the AMD Athlon MP and AMD Athlon64 families. And some motherboard companies offer the chance to unlock the Pentium 4 (Socket 775 CPUs only) overclocking potential by using special bios, for more please read:
http://www20.tomshardware.com/motherboard/20040916/index.html
Look at your motherboard
Before you overclock anything, have a look if your motherboard can overclock CPU. Look at the CPU installation section in the motherboard manual. Normally you will find either BIOS setup options or jumpers on the motherboard that allow you to adjust the FSB, CPU voltage, PCI/AGP ratio etc.
If you have a computer that came from a major manufacturer like HP, it is likely that your motherboard does not provide any overclocking function although it is very rare nowadays.
You need more Power!
This is also the time to check the power supply in your computer. Like a car, speed requires power, and unstable power inevitably leads to unstable processors, so I would recommend the power supply has to be at least 350 Watts. You can find six power supply guides in this forum below:

AND
http://www.extremeoverclocking.com/articles/guides/Power_Supply_Guide_1.html
Both Intel and AMD processors are power hungry, consuming 40 to 100 watts (e.g. the new Prescott) of power. Also, your graphics card may take another 55 watts of power. Now you are consuming more than 100 watts of power for merely two components in your system.
You can also voltmod your Power Supply Unit, for more please read:
http://www.xbitlabs.com/articles/other/display/psu-voltmodding.html
Using higher voltages
Today, almost each processor can be run faster than the speed it was labeled for. This applies even more if you raise the core voltage a little bit. This is just like a car running at higher speed requires more power. But this is one of the “riskiest” aspects of overclocking - by using too much power you could burn your CPU. You should always raise the voltage step by step and never go higher than 15% beyond the specification. This way it is quite easy to get a faster system without risking the processor. Apart from raising the voltage of the CPU, similarly you can raise the voltage of memory as well. One problem is of course the increasing chip temperature, so cooling is very important. We will cover that later.
Memory Speed
Memory speed is often tied to the FSB. For example, a Double Data Rate (DDR) 400 memory has frequency 200MHz and the module rating is PC3200. Half the performance increase you may see from overclocking a CPU comes from increasing the speed at which the processor can talk to the memory.
When you buy memory, you may see it has label 2-3-3-7-1T. And you may also hear people saying my memory is a 2-3-3-7 one. But what does it mean? The answer is:
CAS Latency = 2 clock cycles
tRCD = RAS to CAS delay = 3 clock cycles
tRP = RAS Precharge = 3 clock cycles
tRAS = Active to Precharge = 7 clock cycles
Command Rate = 1 clock cycle
Different motherboards may call the above differently and not all of them will appear in the BIOS. You may need to check with your motherboard’s support team and the motherboard manual. If you have any option above in your BIOS, you can also start to adjust them. Obviously, the smaller the number the faster the memory will be.

Video Card
To overclock video card, we need a third party utility to overclock the card. Although increasing numbers of manufacturers include utilities to allow customers to overclock their cards in their drivers or through an extra application, most of them do not provide this facility. Simply because overclocking stresses the system and voids manufacturer warranties. Third party utilities tend to be universal that they work on different cards irrespective of manufacturers.

Get the temperature down
Cooling is probably the most important aspect of overclocking. Overclocking causes circuits to cycle faster, generating more heat. If the CPU is not cooled properly, your CPU will not run reliably and there is a very good chance that you will permanently damage your CPU.
The heat sink and fan unit that Intel and AMD ship with its CPU are fairy good. However, for maximum stability, we need to get something better than that. For example, for CPU fans, we have Vantec Tornado, Thermaltake volcano 7+, CoolerMaster Aero 4 and Zalman CNPS7000A-AlCu etc.
Be sure that the cooling solution you choose is specifically designed for your processor. Improperly mounting a heat sink, using the wrong model can damage your processor.
Also, the airflow in the case is very important. If heat cannot escape the case, the CPU is still at risk. Thus, more case fans are needed apart from the power supply's exhaust fan. Tidying up the cables inside the case can help too. In addition, clearing the dust in the case by using canned compressed air can enhance the airflow but never use vacuum cleaner as it may generate electrostatic and harm the IC components.

Overclocking Process
Essentially, overclocking processors consists of increasing the FSB in the BIOS, booting the computer, and then testing for stability. You repeat the process until you identify the maximum stable speed.
In case your board offer 1 MHz-increments (which most of your boards do), you have the chance to find out the maximum clock speed by slowly closing in on the final limit MHz for MHz. Of course this cannot be done in an hour, but you will have to spend one or two days just playing with different clock speed settings. In the end you should have your CPU running at the highest possible core speed. The Most important thing to remember is that you must go Slowly!
Also, you can overclock the processor by using software although it may not be as effective as overclocking using the motherboard BIOS. Such software includes:
1. ClockGen

Here is a thread that talks about overclocking an Intel Pentium 4 2.4cGHz to 3.0GHz using Intel 865PE chipsets. (You may treat it as an example of overclocking.):

Changing the FSB is a relatively simple matter of entering the computer's BIOS setup screen, switching from automatic to manual configuration and selecting the FSB speed you want. Here are some utilities that you can check your computer’s setting, especially CPU speed:

Bear in mind that if the processor is capable of a 20-percent or more speed increase say, it is unlikely that your video card or memory can have the same amount of increase. And the one thing that you must remember to do if you overclock the FSB is to Set (i.e. Lock) your AGP/PCI Buses, to as close to their Default Frequencies as Possible (to PCI bus at 33 MHz and the AGP port at 66 MHz for example), or you will most definitely experience problems across the whole board e.g. your graphics card, onboard sound and IDE channels may start giving you data and other errors.
Test for Stability and Benchmarking
The purpose of testing is to apply a heavy workload to every aspect of your system to ensure that there are no hidden problems and stability issue. You can do testing by using special testing suites, software and games. The aim of benchmarking is to measure the performance of your system. In overclocking, benchmarking can tell you how far the system’s performance has increased when you adjust certain settings.
For a test suite, you may try Winbench, which you can download from:

I tried to overclock my p4. 2,66ghz to 3.18ghz.
l increased the cpu fsb only since the multiplier is fixed at 20x.
l tried to change it but couldn´t.
l then increased my cpu voltage from 1.525v to 1.732v.
At 3.2ghz, the computer was on and restarts automatically, so l turned it to 3.18ghz.
does it mean the cpu will not overclock further or l need a new cooler?
I did not overclock anything except the fsb.
any help?
I have a 2.6C Northwood pentium 4 on an MSI 875P Neo2-FISR mobo. On air I'm able to get it to about 3.14Ghz stable. I don't believe it's a good idea to go past 1.6 for the voltage, from what I've read, voltage doesn't help too much with the northwoods.
I can overclock mine higher without any significant changes in temperatures, but the overclocks aren't stable and the system freezes up from time to time. I'm using Kingston HyperX PC4000 DDR, which can run at up to 500mhz, so I can do a 1:1 ratio on the overclock. I'm using a modular 500-watt power supply, Arctic Silver 5 and a huge honking Swiftech heatsink with an 80mm fan.

HP Product Research

My mac was having trouble. It would stop in mid-song or video.
I have burned out a hard drive (told due to old age), bought it about 5 years ago (~late 2007/early2008), and accidently fried my CPU (my fault). So, while the hard drive and CPU is only about 1 year old, I use it a lot and thought maybe it was almost over.
At first I did a disk check and a kinds of errors came up. Tried to fix, will maybe check again later.
The fan was coming on when nothing was really running, so I started the system monitor. It said "HP Product Research" was using 192% of my CPU !!!
I FREAKED out! I uninstalled everything HP and the CPU settled right down and the fan turned off (Phew!).
At first I was worried it was a back-door virus of some sort. Now I am thinking it is just HP incompetence.
Here is my question: Since I do not know how long this was going on, I am concerned this may have 'over-clocked' CPU, burning it up and the hard-drive. In other words, it seems like I just did the equivalent of putting a 'million miles' on my hard ware.
Does this make sense?
Has anyone else encountered this issue?
Not really interested in the $0.05 I would get from a class-action suite, but dang! HP doing anything to address this?
Is this now fixxed? Do I need to do more (other than forget I own HP products) :_)
Thx!

At first I did a disk check and a kinds of errors came up. Tried to fix, will maybe check again later.
This is probably the source of all your problems. If your hard drive has multiple errors, and it couldn't be fixed (as seems to be implied by your statement), then you can have all manner of issues. Any time you have unrepairable hard drive corruption, you can easily have problems ranging from failure to start up at all to frequent crashing to individual apps misbehaving. Data loss is also a very serious possibility.
It is possible that your hard drive may be dying, so be sure that you have all data backed up. Then, I would probably erase the hard drive and restore the entire system from a backup made prior to the start of all these problems.

Help I think my power supply is going bad! Where can I buy parts?

I am getting random reboots and it doesn't seem to be the OS... My first guess is the power supply but I can't seem to find one to buy... Does anyone know where I can buy one at? Is there a good place for parts for the MEGA 180?
Thanks
Mobile Bob

you need to post more information about the problem you're having, before we start pointing the finger at the PSU, which is the one part that is difficult to obtain now
>> Getting help with random restarts and blue-screens <<
Post more info on the hardware in your Mega PC, refer to >> Moan Guide <<
Download Speedfan and use it to measure CPU temps both at idle and under load and post them here. >> How to use Speedfan <<
Test your memory using >> Memtest86 <<
The thing is that windows never leaves an error... I get nothing in the event viewer except windows was shutdown error no other errors are listed so I don't think it's windows... I ran a CPU Burn in test for over 24 hours and never had a problem so I don't think it's heat either... And the reboots are quite random I will go two weeks without one and then get them two and three times a day... To me the power supply seems to be the easiest answer but since there hard to get I guess it's not so easy to check eh...
I have done the fan mod (Turning it so it sucks in cool air) and I have a slot fan dumping tons of air out the back so I don't think it's a heat problem... I started to have the problem running Windows XP SP2 so I did a complete reload from scratch to Windows Vista (I know not completely supported but it works fine) and am still having the same problem... I have a Haugpauge 150 pci card, Haugpauge USB2, A usbuirt pluged into usb and thats about it... 2 gigs of ram 2x1gig sticks from Crucial, yes I have already run a memory check and it passed...
Is there not anywhere to get a power supply? Or is there another model that fits the mega 180 case?

Weird random crash

When i am playing games, sometimes i get a random crash. The crash is like the game freezes, the sound starts repeating really fast, almost like a buzz. The only thing to do is hit the reset button. Once i hit reset, the post code indicates a video error, (ami bios, 1 long 2 short). But if i power off, then power on the post screen comes up and says "The previous performance of overclocking is failed" (even though i was not overclocking!!!) I then hit space bar to go into bios, save bios and exit, and everthing is fine.
This is generally during games, it started with far cry 2, i thought it may have been an issue with the game, but then it showed up in crysis warhead, the witcher, and most recently arkham asylum among others. In arkham it seems to happen at the end of the combo when it goes into slow motion knocking down the last bad guy. But other than that i havn't found any patterns.
it would also happen whenever i tried to update the same game with the ingame windows live update.
this seems to have appeared after i changed processors, but ... read on
I am fairly confident it is not overheating, all system temps remain stable and system is well cooled.
I have stress tessed the cpu with 4 windows of cpu burn in, for around a day long, with no issues, also stress tested with prime 95 for a long (approx 20 hours ) period with no issues and good heat dissipation, so it makes me wonder if it is the cpu?
I have stress tested the video card with ati tool, video card stress test, furmark ozone3d, and 3dmark 06 with no issues. furmark raised the temp way higher than any game has and nothing wrong.
I updated motherboard bios thinking maybe it was an issue that had to be straightened out with the chipset, but no difference. (before i update i had ami v1.8, and instead of 1 long 2 short, it was 8 short beeps, but both are video card related)
all drivers are up to date..
tested memory for 20 + hours with memtest 86+ and windows memory diagnostic, both reported no errors.
* Motherboard brand & model- MSI k9a2 neo-r
* CPU model (and is it overclocked?)- amd x4 940 be (at stock)
* Video card(s) evga 8800 gt, 512mb
* RAM modules brand & model patriot ddr2 800, 2x 2048
* Power supply brand & model silverstone st50ef plus 500 watt
sound blaster audigy 2 zs....
I am going to swap the 5000 back in, and see if it still occurs, since it showed up when i change to the 940, but just wondering if anyone had any input or seen anything similar before. But the bios beeps referring to video problems also make me wonder, maybe the board itself can't handle the cpu.
Thanks

Ok, so I think i have made some progress, it doesnt seem to be the cpu.. but it is the video card. I did a few more stress tests and noticed that the card (using furmark) was reaching 100+ degrees C.( while cpu stayed in mid 30's) Around 105, boom, computer crash. I didn't think I was reaching this high of temps in games though, so I need to find a way to monitor the gpu temp in games. It is kind of weird that this started with the new cpu though.... but i put in a new cpu fan as well, I added a xigmatech hdt -s1283, so maybe it changed airflow or something? I need to explore this a little further tomorrow. Will also apply some mx -1 paste and reseat the gpu heatsink. and improve case airflow if possible.
This is kind of puzzling still, because from alt-tabbing in and out of games, or looking at evga precision after a session, the highest gpu temps are typicall less than 80 under load in games.
