ARRGGHH!! Dead CPU? Or Mobo?

OK... rather than explaining again what's happened, can anyone have a quick scan at my thread at the AMD forums and maybe offer me any advice or suggestions? Basically, I think my CPU is dead, but I can't tell for sure just yet. Could it be the mobo?
Thank you in advance for any help. I really need to get to the bottom of this one because I am broke and can't really afford a new CPU, mobo, or both...
Here's the thread: http://forums.amd.com/index.php?showtopic=48642

It's OK, I got it working again. No amount of clearing CMOS and switching the jumper was working, but I followed some advice I found on this board about holding the Insert key as the system was powered on. It booted for the first time in 2 days! I'm happy now. Cheers for the help.

How can I tell if its a dead CPU or mobo?

Hi,
I am trying to fix a friend's dead (sort of) computer. He said the computer just stopped working and wouldn't restart. The "TCP" smell from the PSU suggested it had blown.
I've put a new PSU in (Mercury 400W - 3.3V@28A,5V@40A,12V@17A) and the following happens: the computer starts, CPU and PSU fans run, DVD and DVD-RW lights DO NOT light up and will not eject, there is no sound of the HD spinning, there are no error bleeps, on the D Bracket 2 all four lights light up as steady red!
The last suggests that its CPU - but surely I would get error bleeps too if there was a problem with the CPU??
How can I be sure that it is just the CPU and no mobo damage - I don't have a spare socket 754 mobo or CPU to try.
thanks in advance
Cheers

Richard,
No Jedi Mind Tricks or anything else needed - all the computer specs appear at the bottom of my original message - its a 7030 Ver 1.
"P.S. Which two lights are Red?" - don't think I mention two red lights anywhere in my original message, there are four lights on the D Bracket 2 - ALL ARE RED!

Hi my friend!
To check what part of the computer that is damaged and not working disconnect everything inside the computer, CPU, Memory, Graphic card any IDE drive etc.
Now, make sure that the PSU is only conected to the motherboard and nothing else, also connect the power sw and power led.
Now, power on the system, if the system is not powering on check the power sw, if its still not powering on then it's likley that the motherboard is damaged.
If it is powering on the put in the graphiccard and try again, if an image is displayed saying somthing like processor or cpu missing, go ahead and install the processor with cooling and try again, if you still get this messege than you know its a problem ether with the processor or the socket, if you ain't getting processor error messege but memory error messege than you know that the processor is working some what well.
Anyway, the only way to test the socket or processor is by putting it into another hardware...
But this testing is at least some fingerpointing to the problem...
Yours ChalkyGBG!

[875P Neo FIS2R] Dead Mobo or dead CPU?

I've got the Neo FIS2R (PCB 1.0) version with a nothwood 2.8C CPU and all of a sudden, a couple of days ago my system stopped working.
When I press the power button the fans work just for an instant and then everything stops...
One thing I've noticed though is that, either with or without the cpu on the board, when the 4-pin 12V connector is not connected, I can power up the system and I got 4 green leds on the D-bracket. Once I connect the 12V again, I cant power up my system
I've tried with a different PSU and with all the cards, drives etc disconnected and I get the same results.
If anyone has any idea, if it is the CPU or the mobo that is dead, please, please tell me

Hi Maesus thanks for your input.
The problem is that i dont have access to another S478 board, if I did things would be much simpler indeed...
By the way another thing that came into my mind, is that I have 1GB RAM (2x512MB dual channel at "fast" setting in the bios) and I had overclocked the CPU from [email protected] by increasing the FSB @ 215MHz. I had also increased the core voltage of the CPU @ more than 1.6V. The AGP and PCI buses were left at default speeds but the AGP voltage was increased a little as in some games I overclocked the video card as well from inside the windows.
The past couple of weeks or so, I had all kinds of BSODs (from STOP 0x0000007f errors to IRQL_NOT_LESS...) out of the blue quite frequently, either when running specific applications or completely randomly.
I am mentioning the above, because I've read in other forums that it is a frequent phenomenon for Northwood CPUs to die when increasing the core voltage above a level (SNDS) and one of the symptoms indicating that the CPU is dying is frequent BSODs a few weeks before they die.
In fact, before my system died, I had a BSOD and after that the computer shut down and couldnt be turned on again (I saw the BSOD when I was sleeping...but not in my dreams and the next morning the system was dead. I have disabled the auto-restart after a BSOD in the windows).
Any help will be appreciated.

Dead Board or dead cpu?

i have ( had since it doesnt power on anymore) with the following
AMd 64 3500
K8N Neo2 platinum ( with latest bios)
lDDR400 2x 512meg Legend memory
Sata hard drive
Dvd combo MSi
Albatron 6800GT.
The machine refuse to power on . Press the power button nothing. tried different power supply nothing.
Disconnected vid card, drive , evrything ...no power on, well it switches on for like a millisec and goes dead again. if I press pwoer button again nothing, if i unplug then switch it does the millisec again then dies again.
I installed that Msi core application was set on cool and quiet no overclocking. this morning boot the machine the fan was at low speed temp was around 60 degrees, i got a message from that cor center saying temp to high .do you want to shut down I did immediatly. reprted temp was 80 degrees.
tried to reboot no power on cant even see the blue light on the case main switch.
Tried to reset Cmos to no avail.
Anyone has suggestion?
is the motherboard faulty or is it the cpu?

I sure hope you aren't another one of those people. After all we really don't have anything to do with MSI except we also purchased a board, got it to work, and decided to try to give back something to the community by offering free advice to those who appreciate it.
BTW, anybody who has RMAed 3 mobos purchased it from a vendor who allows anything to be returned whether it is actually bad or not. You may get a bad mobo now and then, but two in a lifetime is stretching things, and 3 means you should have bought a $60 million lottery ticket instead of a PC.
I agree the chances of this happening are ultra slim not to say impossible. Something else would have to be wrong with is set up. I guess I am frustrated by the all thing.
When I bought this machine I decided that with a high end system ( never having owned one bfr) I should have it speced and built for me> So I gave a list of conmponent to MSI delaler and said " ok these are my specs you make it with whatever will perform well and not give me grief and compatibility problems". when i received the system I could not install winxp, the ram DDR400 was in the wrong slots.
That was rectified, everything worked ok ( actually I was very Happy with My system)
High frame rates in games , no freezes after install of SP1. was all good. I am not saying outright ho this MSI 's fault. I am just trying to understand what went wrong, so it doesn't happen again. And i Understand that such new design cannot work 100% of the time and future Bios may aleviate problems experienced by users
When you get a failure you tend generally to blame the latest application or bit of hardware or driver you have installed ( it's human to jump to conclusion).
Lets state the facts in a rational way.
1) my board died foir no apparent reason. ( so it seems I am waiting on the test results. but I assume it did it seems logical)
2)i did not add any hardware, or open the case system was performing great exept for the fact that the fans were going full speed all the time . so a quick look at msi web site + MSI update software, which by the way is great ( finds latest bios , utilitiy version etc all from 1 mouse click, all good)
I installed core centre 1.7 that supports my board, it seemed to work too, fan speed seemed to decrease with temperature, was happy with it.
3 days later system is dead.
NB temp was never reported said N/a What does NB STANDS FOR?
system temp reprted 7 degrees
core temp was between 47 and 60 reported ( 60 after a game 41 to 47 idling or little activity)
so beeing Human and beeing a brand new system I wonder If that core centre app could have reported wrong temperatures giving me a false sens of security while the system temp may have in fact be much higher than reproted? and consequently the motherboard or processor or both are now fried....

Switched CPU now MOBO doesn't Boot

I have an MSI 6378 Ver 3 Mobo. Up until this afternoon it worked great. It was running an XP1800+ CPU. I had someone at work who upgraded and gave me their XP2000+ cpu, so I figured, what the hell. I installed it, but the system would suddenly power down when it started to boot into windows. I would then have to remove all power from the system (disconnect the cord) before I could power it up. So I figured I got a bum CPU and put the old one in. With the old CPU the monitor won't come on, so I don't even know if it is getting to post or not. It sounds like things are spinning up, but I don't have any display. I have a seperate PCI video card, and I get a display with the bad CPU. Can anyone give me some suggestions what I did to my board? I really don't want to purchase a new board/CPU/memory combo if I can avoid it.
Thanks,
Lee

Hello,
You know that you only need a thin layer on the CPU DIE (thinner than paper).
And a small layer on the heatsink.
What heatsink are you using?
Why the XP1800+ wont post?
When you put the XP2000+ in the board runs the CPU at 1.667Ghz.
If you swap CPU's the board may try to run the XP1800+ at 1.667Ghz instead of 1.5Ghz and with the locked CPU's it will cause the PC not to POST.
So you should clear the cmos everytime you change CPU's.
What other components are you using and power supply?
Are you running the CPU at the correct speeds?

Another dead CPU..

Hi
today I received some new RAM and a new cooler for my graphics card.
While the RAM worked spot on....
I took out the Radeon and then installed the VGA silencer.
When i re-installed it, the PC no longer worked.
I believe I think I may have done something to the CPU, but not sure what. It is definitely not working anymore. I have tested all 4 sticks of RAM i have (The Corsair and GeiL) which I KNOW were all working.
And, before anyone asks, the Radeon is now sitting in this Athlon XP 1700 machine of my dad's, working perfectly.
I think i've fried the damn CPU
RMA TIME weeeeee

well i am late in the game, so i try to get up to speed,
here is a posting that worked for someone else
"I know his is your 9th computer build, and i know this is basic, so bear with me here, but at this point you have to do a methodical by the book check list.
when you mounted your cpu you....
1 ___you properly handle equipment so no static damage can ouccur, (properly grounded)
2____.you fully lift the cpu ziff socket arm up, orient the gold triangle marking arrow,pins and it easily dropped into socket, with no bent pins ,
3 ___ backer plate mounted carfully no missing pices of the board flying off, ( i have seen people launch capaciters, and the like )
4 ____obviously you removed the plastic thermal pad cover, and heatsink was evenly locked down, and fully seated, and correctly pluged into mobo cpufan1.
and you fully removed old thermal pad/grease and applied new artic silver, or new heatsink with plastic on pad,you didnt reuse old paste or pad.
5 _____memory stick(not sticks)i sfully seated and properly oriented in slot, and is 184 pin ddr non-registered , non ecc ram , and you have tried different non corsair, non twinmoss, brands that have been known to work.
6.____ plug in only powerswitch pins 6,8and power led to jfp1, pins 2,4 and they are turned correctly,
7. ____your new psu has the 20 pin and square 4 pin power connector plugged in to jpw1 turned right and fully seated.
8 ____your video card is fully seated an locked down,also securley screwd in.
9 ____your floppy drive cable iss facing right way (pin1 is matched with red stripe)
10. ____you have ata cables for hd and cd set to master/slave or cs. with hard drive set as master, end of cable.
11 _____the power plugs are all fully seated, including psu rear plug,floppy ,hd, and cd.
12. _____keyboard(ps2) and mouse pluged in, monitor pluged into video card,
13 ______every thing is fully secured in case, side cover is off.
14 ______cmos jumper is set 1,2 keep data, usb stuff is unplugged, except for dbracket.
power it up, one beep, fans spin, in psu and cpu, and video card,
you get no bios found error, or hit del tio go into bios, set boot order, and .......
.........your now at the end of the road, and it should by all means work,
now what i am after,
there are no bent pins, on cpu, you reapplied artic silver paste.
no loose wires,
properly applied heatsink with fan cooling,
you have tried different brands of known ,to work in an msi k8tneo
ddr ram 1 stick at a tme.
you have tried different video cards, and in case of higher end card, the external molex power supply as plugged in,
you have tried different ata hard drives
you then have tried have set up your sata drive corectly drives, get to sata later.
everthing is securely pluged in ..fully seated and oriented the right esy?
what are d-bracket error light, and any beep codes?
you have tried a different wall outlet, you have changed surge protectors,
you never hot pluged video cards, hd cables or power etc.
i know this redundant , and basic , it is not ment to be insulting , it is ment to be a checklist and rule out all basic errors and potential problems

Dead cpu

My laptop's CPU is dead. How can I fix it or replace it

Met-M wrote:
I've been told by of hp worker.How did they verify this? AMD or Intel CPU going dead only happens from abuse or overheating environment or dirty environment that would cause thermal overload that will eventually damage the CPU.

Which is dead, CPU or Mother board?

My pismo does not boot up. After pushing the start button.
I assume it is CPU that is dead, but I would like to confirm.
Here is the sympton.
I hear chime. Internal harddisk seems to be spinning.
Nothing on screen. just stay black.
I tried PRAM reset, T-mode start, etc.. no response.
I tried to unplug the internal harddrive from the mother board. no response.
I tried to boot up without RAM, no response..
what do you think?

Kozo,
I believe you probably have the G3/900MHz upgrade card once offered by PowerLogix.
Although no longer in the archives, this post describes your symptoms and the fix.

My faithful pismo (500, 512MB, 30GB) is giving me problems. It chimes, but the screen remains blank. I can hear the hard drive spin up, but not start to read as usual, and no processor noises etc. I have tried different drives; nothing. Can't boot from CD, because it will not look for drives (holding down option, or C, or Command-option-shift-delete do nothing either). It was behaving erratically, booting sometimes with some working at it... re seating the processor etc. My thought is that the processor or L2 cache is shot... but I don't know. I am looking for a working Pismo to swap processors with, so that is my next step. If anyone has a better guess at the problem, or has experienced the same and found a solution, please let me know. I know it is time for an upgrade, but I am hoping to make it to next fall (G5 I hope.) Luckily I have a Dual G5 on my desk at work...

I bought a new (used) 500 MHz processor, and I am back in business. So, I do not know whether it was the L2 Cache or the processor itself, but it started right up. Anyone know of a good use for my old processor? Is there any business that will buy them? Why would they? I don't know.

I believe you would be safe in replacing the microprocessor card. The Daystar G4/550MHZ upgrade cards are actually faster than the G3/900MHz when running applications that are written to take advantage of the G4's AltiVec hardware. I would stay away from the 900MHz cards due to their age and their problematic history.

Dead K7N2 Delta2 Mobo?

I hope someone can help me. I just loaded my new K7N2 Delta2 mobo a couple days ago. It was working fine. I turned it off for the night and when I tried turning it on in the morning it did not boot up at all. Nothing is working... no fan noises or anything. When I push the power on button on the front of the computer, the green light comes on for a second, but that is all. I have swapped out everything in the computer you can think of. Everything works fine in another computer. I replaced the power source and still nothing happens. Is it possible the mobo is shot?

Well, you suspect the P.Su, but you don't say a word about it, nor the specs of the one you used to replace it, so we can't answer at all.

Dead Cpu or board?

Hi,i have an amd64 3500+ and msi neo2 platinum board.prob i have is that my cpu overheats the instant i turn machine on,the board and chip are only 2 days old,first day comp run at 34 idle np,but on 2nd day it wouldnt post so i went into bios and saw temp was high instant,now im lucky if i can even get to bios screen before cpu overheats and locks up,the heatsink and fan are both fine ,it is not that,if a cpu is broken would it normally overheat or just wouldnt post at all? Could it be some sort of board malfunction that causes the excess heat or does it have to be a cpu prob?The voltages in bios are all set to defaults,the cpu voltage is at 1.50 still so its not overvoltage,any ideas or help appreciated...
Thx

Yes all that stuff is as it should be,the heatsink is one i used for a while now and only has a small amount of grease spread as it should be,first day comp was np if heatsink was prob then it would have overheated right off,but something seems to have happened on 2nd day,what i really need to be sure off is which is prob the board or cpu as i brought them off different retailers and have no means to test the cpu or board without one or the other...

Cpu or mobo broken? (four red leds and CD ticking on 865PE)

Hi folks, hope you can help me out.
My 2.5 year old system died today while using it. It's an 865PE Neo2 with a 2.8GHz P4 and 2x512MB RAM.
It doesn't POST and the D-bracket is showing four (all) red LEDs. What is also interesting is that there is some kind of activity on the CD/DVD drive (is ticking continuosly) and the keyboard Num Lock / Caps Lock / Scroll Lock LEDs blink at irregular intervals (all at the same time).
Does this indicate if it is the CPU or motherboard that is broken?
[I have disconnected all accessories + reseated the two power connectors, the memory sticks and CPU but no improvement.]
Cheers
Mike

I bought the computer "ready-made" by a computer manufacturer so I haven't been involved in the choice of PSU, but I expect the specs to be sufficient as they built lots of systems of this model. The computer is a "low noise" model (PSU labelled "w/noise killer") so this has probably affected their choice.
Anyway, the specs are:
DC out: 350W
3.3V+5V: 220W max
3.3V: 28A
5V: 30A
-5V: 0.3A
5V SB: 2A
12V: 16A
-12V: 0.8A
I thought my measured voltages looked fine, but was there something that caught your attention and indicated problems with the PSU? (Or maybe rather the failure statistics you mentioned earlier?)
Thanks
Mike

MSI NF980-G65 what is death - CPU or MOBO

Good day
Please can you help me with MSI NF 980-G65
After increasing the Vcore voltage VID and NB Voltage in the BIOS and save settings for the PC was switched off
Subsequent start without success, PSU only "clicks".
When I disconnect PWR1 additional CPU power supply, PC PWR svitch responds to, the source gets going, but the BIOS appears.
I tried the CPU in another board does not work
The board I tried a different CPU does not work
Please advise whether it is a bad CPU, motherboard, both, or was damaged only to the BIOS.

I don't know if there are beeps for faulty memory on this motherboard. Please try memory, too.
Did you maybe mistype, that you get to BIOS? If you did mistype, things are not as bad as you fear.
Memory??
I try to turn on the PC, nothing happens. Only when I disconnect from the motherboard connector PWR-1, the motherboard gets going, but unfortunately no image

Question about hwmon; knowing which Temp correspond to CPU or Mobo??

Hi all, well my problem is this:
I want to monitor my CPU temp
I have a Athlon X2
So reading here in the forums, i read how to use conky and hwmon to display the temps. So far so good, BUT in: /sys/bus/pci/drivers/k8temp/
i get 2 readings, temp1_input and temp3_input, so since im a noob, i realized that temp1_input was always hotter than temp3, so i said: ok, thats the CPU temp and the other its the motherboard, BUT when i start to do demanding things on my PC, the supossed MB temp get olmost as hot as the supossed CPU temp
So now i dont know if each reading correspond to a core, and temp1 + temp3 equals to my total CPU temps, but the readings of the temps in the BIOS shows that the temp is actually like temp1_input (like 32 ºC), so that make me wonder that maybe my MB gets hot as the CPU which i find it weird (right now temp3_input shows 26ºC
So my question is, how can i know for sure to which component those temps correspond??
Anyway that i can provide more info please tell me how
And thanks in advance for any help :]
using Ksensors, it shows that temp1 correspond to core0 and temp3 to core1, so that means my CPU is at olmost 60ºC :S??
its a brand new X2 5600+ whit artic silver and a good cooler (nothing fancy but still)
Last edited by AlmaMater (2007-12-05 06:44:29)

I wouldn't care about it If each core stays below 45-50°C.
And you'll never get exactly the same readings for both cores as it's very unlikely with today's software that both will be used uniformly.

Dead or defect mobo ?

heyya all ive just got this KT6 Delta FIS2R and a was away from my com and when i come back it had hanged i rebooted and the D-Bracket hangs at the Memory Detection test witch means that the memory is bad well i just bougth one new block today and it stays??? somebuddy helpp

G33M-FI mobo is overvolting my e5200 cpu. Is it normal?

Hi, I've searched trough this forum but seems anyone has my same "problem".
The MSI g33m-fi mobo I just bought (brand new, 1 week ago) works fine, but it "overvolts" my cpu.
It adds about 0.06V to EVERY Vcore I choose from Bios, no matter if it is the "default" Vcore settings or the "manual" settings.
Examples:
1.1500V (stock default VID for my cpu @idle) -> 1.22V as read by CpuZ utility
1.2375V (manually choosen inside bios) -> 1.30V-1.31V by CpuZ (with spikes up to 1.35V )
I have not tried any higher voltages because I don't want to fry my brand new cpu.
Why my mobo works this way? Is it a bug or is it a regular thing? It's the first time I see a mobo overvolting the cpu (usually they do the opposite - they have the Vdroop "problem").
Also, do you think they will release a new bios anytime soon?
Here I list my system''s specs:
e5200 cpu (with OCZ Vindicator cooler)
msi g33m-fi mobo Rev 1.0 (latest bios 1.3, g33m + ich9 chipset)
2gb (2x1gb) Geil Ultra ddr2 800mhz ram
ecs 9600gt graphic card 512mb
SB Audigy ES audio card
WD 500gb sata2 hdd
lg 20x dvdrw sata
internal (usb 2) memory card reader
Antec nsk3480-eu case with
Antec Earthwatts 380w psu (12V1=17a, 12V2=17a) (combined 12V rails = 27A)

Quote from: NovJoe on 04-November-08, 17:54:31
A little sceptical on your 380watts Antec, however, I would suggest you to check if EIST has been disabled in BIOS.
well, I tried both options, with Eist enabled / disable, but it's the same.
Right now, with Eist disabled, Vcore is 1.21V (sometimes goes down to 1.19V). The VID for my cpu is 1.15V in Idle mode. So 0.04V or 0.06V added.
My cpu is a e5200 with S-specs: SLAY7.
I'm using the integrated graphics now, and removed the 9600gt, just to check if it is a PSU problem with supplying enough Ampere to the system.
Anyway, the same PSU has been used with a e2180 @2700mhz @1.31Vcore effective, and the same configuration as described above (including the 9600gt) but with a different mainboard, an Asrock with 945G A2 chipset. And it never showed such behaviour.
Could it be a wrong setting into the bios about the Vcore to be supplied to the cpu? ???
Other friends have the same cpu (different mobos) and nobody has the same weird overvolting (actually, they got the V-drop issue).

ARRGGHH!! Dead CPU? Or Mobo?
