K7n2d Ram or Psu?

Well I've read all of the trouble shooters 101 and ran around through buying the right psu and memory threads. But I'm not really sure if this isn't a mobo issue rather then one of the aboce.
I've got:
amd xp barton 2500+
Kingmax 512 mb ddr 333 KDL388P4LA-60 on chips
radeon 9600 pro
the power source is too weak for sytem and I've got one suitable otw just as I want to eliminate that problem.
Symptom: Will not even display during boot. bluetooth says "processor damaged or improperly installed error" 1&2 red 3&4 green.
I've reseated the processor with EXTREME care following a nice guide on arctic silvers site (was a real help I just used to blob it on and smear it around , has a big vantec on it.
1hd 1 cdrom 1 floppy, not much there really but my psu has these stats:
+3.3v ~ 24a
+5v ~ 35a
+12v ~ 12a
I guess my question is, does this, my psu, look to be like my problem or could it be my mobo or memory?
Thanks,
Whitt

So,
I've replaced the psu on this with an antec 430 purepower and still recieving the same issues. Absolutely nothing gets written to video. D-Bracket lights 1&2 red, 3&4 green.
I'm at a point where I wish to replace my ram, or perhaps my mobo, but was curious if I could just remove all ram from mobo and get any further along in the boot process if its bad memory holding me up?
Not sure if this is very clear but if ya do understand what I'm trying to say and know if its possible to boot to bios without ram could ya let me know
No, I don't have any way to test ram on another ddr mobo, nor processor with a mobo the correct bus speed. I think its the mobo holding me up but I just hate to keep buying new stuff and swapping parts to fix this.
Thanks,
Whitt

Stalling problem, could be ram or psu...

Here's the long story...
I finally got my new pc up and running then noticed it stalled every 2 hours. I contacted MSI and with a speedy reply they told me to up the voltage on my AGP to 1.6v . That was great, was working fine for almost 3 weeks and I had in on overnight without any stalling whatsoever. All of a sudden its starts freezing up on me again. I read around these forums which are great btw! :P And I upped the voltage on my RAM to 2.7v since it's DDR400. Didn't stall all day. Shut my pc opened it up the next day... same problem... upped the voltage on RAM to 2.75 and on AGP to 1.65v, worked fine for a while then started happening again. How far do I up my voltages? I don't know what to do at this point as it seems as i can't avoid this stalling
Your help is much appreciated, thx. Plz don't tell me its my PSU

Hi,
I use Enermax 465 series personnally...... but Antec are also a good/equal to Enermax.

Shame they do not ship to UK.....
Would advise researching, as some PSU's "CLAIM" 550w but are no better than a GOOD 250w....

What causes my instability? CPU? RAM? PSU?

Hallo community,
let me start with a short description of my problem:
I am unable to get my system (see signature for details) working stable in synchronous mode: when both, CPU and RAM, are working at a FSB (or HTT) of 200 MHz, the system crashes randomly with various error messages (mostly memory related). It is possible to reduce the number of crashes by using memory slot 2 or 3 instead of 1, but the system is still unstable. The currently only way to solve this is setting the memory to 166 MHz in the BIOS. It should be mentioned that with the former motherboard (K8X800 PRO 2 from ALBATRON based on VIAs K8T800) everything was fine.
What i have already tried:
First of all, i replaced the motherboard with the AN51R from SHUTTLE - no difference, as long as CPU and RAM works with 200 MHz, the system is highly unstable. I tried various RAM sticks -A-DATA, CORSAIR, GEIL and KINGSTON- but also without success.
What i consider to try:
I feel unsure. In one of the guides it was recommended to use a PSU that deliveres at least 24A on the 12V rail - my TAGAN deliveres "only" 22A. Since i can solve my problem by reducing the memory frequency, i do not believe that replacing the PSU will help. What remains ist the CPU: i own a CLAWHAMMER stepping and i know well that the newer NEWCASTLE stepping uses a revised memory controller. On the other hand, this CPU did fine while using a different chipset. As i told - i feel unsure.
Any help is highly welcome.
Thank you in advance,
JePe

One stick (512 mb) in currently slot 3 - since this worked best for me. And no, i did nor ran memtest until now, since ... i do not own a floppy drive . Beside this, i really cant imagine that all memory sticks i tried had the same weaknesses.
Greetings,
JePe

Ram or PSU problem

I just brought a K7N2 Delta ILSR with an Athlon XP 2800, its been a week now and im having nothing but problems with this board.
I when i replaced my old processor and motherboard everything was working fine....for the first 10 minutes(if im lucky).
When i set the FSB to 166 my computer will crash, reboot or not load windows XP at all, even freezes in the bios sometimes but when i set it to 133 which takes the processor down to 2200+ everything is fine. I have tried changing the ram 4 times and im getting the same problem at 166. These are the types of ram I have tried
Hynix PC2100 256MB DDR 266MHZ CL2.5
Nanya PC2100 256MB DDR 266MHZ CL2.5
Samsung PC3200 512MB DDR 400MHZ CL2.5(made in Korea)K4H560838E-TCC4
Crucial PC2700 512MB DDR 333MHZ CL2.5 CT6464Z335.
All of these I have tried in different memory banks running alone.
I ran memtest when my computer was set to 166, its crashed at 5%, set it to 133 and tried again, completed tests with no errors.
Ive tried 3 CPU fans with the paste, disconnecting all the hardware apart from the HD and graphics card(Geforce 4 4200ti 64MB AGP X4) as im using a 300W power supply, played around with the mem timings, updated the bios through dos and none have worked.
So can anyone give me some help please in what to do, Ive spent so much on on buying different hardware nothing is working and I dont want to spend more money on buying a new power supply if the computer will still crash.

Please list the corresponding Amperages on the +12v, +5v, & +12v lines on your new PSU, should be on the sticker.
You said something about getting Kingston RAM, as Deathstalker mentions
Quote
malachi,
A word of warning, Kingston is hit or miss at best with nForce.
You could be recreating the same problem by picking up incompatable RAM and underpowered PSU's Even though a PSU maker claims it's a 400w, doesn't mean anything untill you look at the amperages and figure out what the combined wattage is and what it's continuous load capabilities are.
If all is well and you can't find RAM to work properly or get the CPU to run at 166 if it is in fact a Barton, then you need to look to the board or the CPU. It may server you better to take it to a tech near you that is familiar with that setup, I don't know your location so I do not know the availability of such a service in your area.
Either that or you end up spending even more money/time on troubleshooting it further.
So lets have the corresponding amperages on that PSU for starters.

790FX-GD70 Ram Problem (PLEASE HELP!!)

Hello all,
I recently installed my 790FX-GD70 motherboard with all the ram and all that
I have 2x4gb RAM but when i put both sticks of ram in i do not get anything on the screen but when i install 1 stick of ram into the 2nd dimm windows loads up and all that but after like 10-15minutes i get a blue screen and at the bottom it says "Dumping Physical Memory to Disc" then it reboots loads back to windows and does the same thing again, but i dont know why when i put 2x 4GB ram the same the computer boots up but nothing comes on the screen.
Any help please?
Really need to fix this.

I got these numbers of the ram itself so i don't know which is the model number and the serial number.
And the voltage of the ram is at default. 1.5 i think
I did try and set the voltage to 1.8 and put my 8gb ram in, it booted up to windows and i managed to put 2 sticks of ram in then about 10 minutes later it went to blue screen again and said dumping physical memory to disc
I done a error check of the ram and it came up with no errors.

MSI K7N2 DELTA-ILSR ( MS-6570G ) AGP DISABLED PROBLEM

Hi . i have the above MB + Radeon 9800 pro graphics card + 1gb of ram + 550w PSU + 2.8 athlon XP. Bios is set to enable agp8.
AGP is always disabled and will not switch on . Even when i try to enable AGP thru the ATI SmartGart software the system reboots with AGP disabled
Latest ATI & Nvidia drivers have been installed.
What should the bios AGP settings be ?
Please help..
Regards SR

Hi All,
Its a 1yr old pc i built myself and worked fine with a Hurcules Geforce card.
Reloaded the Nvidia driver from the link above and AGP is now working on 4x. Do you have the Audio driver separatly as it the install stops responding whilst loading the audio part ?
You were right about ATI not liking 8xAGP, it runs like a dead dog with that switched on.
My PSU is gold but with two 120mm fans & is branded "Colours-IT" what brands or models do you recommend ?
Many thanks for the help so-far, my pc finally plays "call of duty2"
Regards
Scott

Anyways..I've been experiencing problems with gaming for the last few months or so. I'm not getting system lock ups, reboots, or BSoD's at all. What I am getting is intermittent freeze-ups, and Windows has stopped responding errors on and off. Sometimes while gaming, everything just locks then I see the mouse icon change to the 'busy' image, then it unfreezes and goes back to normal. It also occurs when I login to games, and the graphics are loading. I can hear a very very soft and subtle noise from within the PC. It's a sort of 'click' sound, but it's not a typical 'broken' click-click-click noise. It kind of sounds like the GPU is just trying to 'do' something and whenever it's doing 'that' it makes the sound. I haven't underclocked/overclocked the card at all. I tried to increase the settings just a little to see if it would help. It doesn't seem to be doing much.
I'm guessing the problem is related to the Gpu, Psu, or HDD but I have no idea how to tell. I'm reluctant to bring it into the shop again. The PC came with a GTX 470 about three years ago. After about a year of using it, it started causing me BSoD's, system lock ups/reboots, etc. When I replaced it with this 660Ti all of those problems stopped. This gpu is roughly a year old now and these problems only surfaced within the past 6 months or less. Sometimes when I game I run two clients of the program and I leave games running constantly. I'm not sure if that has anything to do with this.
I've tried running Spybot, and Malwarebytes. Neither have found anything obvious or virus related. A few weeks ago I downgraded from gpu drivers from around March 2014, to some drivers from a year or two ago. I wanted to see if older drivers would add stability at all. They haven't seemed to do much. The graphics load a little slower in games now, and the freezings still occur. As far as computer temperatures, I haven't noticed anything abnormal. Usually the card runs at 30-45C and I've never had a BSoD. Before I downgraded the drivers, I was getting a lot of driver crashes in Aion. It wasn't happening in any other game. (Aion uses Cryengine) Anyways, I'm not sure what to do anymore. I'm reluctant to buy a 3rd gpu because I'm not sure if the GPU is faulty, or if it's my HDD or PSU.

You mean when you get intermittent freeze-ups, windows also shows error messages? What kind of message?

Have you use another mouse to try if it's not because of the mouse?
If you already tried different MSI drivers and they didn't do much, maybe you can try the drivers from NVIDIA website. (Remember to uninstall your MSI driver first)

Hello. Starting about 1 month ago I've been experiencing this issue. I can be just cruising the internet watching youtube video and listening to music then the computer will freeze and this loud screeching sound would come out of my headphones (and scare the crap out of me). This issue never occurred while I was playing any PC games until recently.
Yesterday I was fed up with the issue so I pulled open the case and cleaned every fan out (which I do every couple of weeks). Now the issue seems to be occurring while playing video games or listening to music. All the fans appear to be functioning properly and I don't believe it could be heat related because I have the Antec 1200 case which has 6 case fans. I've run PC Wizard 2009 and SystemFAN while playing some games and none of the temperatures I saw look too extreme.
So I'm suspecting it could be the RAM, soundcard, PSU, or motherboard but could use some more assistance before I start RMAing it.

I'd be inclined to blame the Creative drivers for your sound card first. Try updating (or if necessary, downgrade) the drivers and see if it makes any difference.
I actually pulled out the sound card an hour or so ago and removed the drivers. I'm running on onboard audio and the system just randomly restarted while I was talking to people on Ventrilo.

Computer shuts down when playing a 3D game...

The weirdest thing... my computer won't run any 3d application anymore. If i try and run Command and Conquer Generals, fifa 2004, or half life (all 3d games), it dies. Yet i can happily run Rollercoaster Tycoon 2 (a 2D game) for hours without a hiccup. When I say it "dies", all i can do is describe what happens...
I can run the game for about 2 minutes (if I am lucky) and then...
1) it freezes for about 5 seconds
2) the monitor turns itself on standby (yellow light insteadof a green one)
3) i can still hear the music, but it stops after about 20 seconds
4) i can still hear the fans working, and the green light on the front of the comp, but nothing works, none of the keys, alt f4, ctrl alt del, nothing.
5) I have to turn it off at the back and use the power switch to turn it back on again, and it loads up like nothings happened.
How strange is that? Let me just emphasise something... I hadn't changed a thing before it started happening. I hadn't changed the software or hardware for about 6 months, no driver update, no change of graphics card, no overclocking... nothing.
My specs are
Msi KT4v agp 8x mobo
AMD t'bird 2800+ xp
1.25gb ddr ram
350w PSU
Radeon 9500pro 128mb
300gb Maxtor hdd
200gb WD hdd
AC97 onboard sound
DVD drive
CDRW drive
3.5" Floppy
I've run a virus checker, reformatted and reinstalled WinXP w/ sp1 (thought that would fix it, grrr), updated the bios ages ago, checked the hsf/fan is seated correctly.
What do you think? I'm not too tech savvy but I reckon something has burnt out and damaged slightly. I leave my computer on 24/7, and my small room can get pretty hot sometimes. Possibly the gfx card, or the memory on it?
Cheers.

:-D)crap, sorry about that, new here, solution got erased im such a dumbass
try adding a case fan if space available in case, get one cheap and good at http://www.newegg.com
good luck

K8N Nforce 3 Motherboard Overheated and died, Argg!!!

Hi, apologees if this post seems long, but i would like to tell you everything i know to get the best possible advice.
Firstly i have the following hardware plugged into my "MSI K8N Neo Platinum Nforce3 250 SKT 754 SATA GIGBIT LAN 7.1 Sound Retail Box" :-
An AMD 3400+ 64bit 754 pin processor
1Gig DDR 400 ram (2 sticks)
Radeon 9600 XT Graphics Card
anouther 5.1 sound card (PCI)
A 120Gb IDE western digital hard disk
A 250Gb SATA western digital hard disk
IDE DVD-RW drive
Couple of USB devices running from the computer
Windows XP
All of the above are in a cheap computer case with a 500 Watt PSU.
The weirdest thing is that my motherboard has been working fine for a good year (it has been running all of the above for at least 4 months now). Then, a day ago I was working on my computer and must have stopped at about 10 pm to watch some TV, leaving the computer on behind me, monitor switched off. Please bare in mind the computer was left idle (running Windows XP, no screensaver).
Half an hour must have passed and the computer SUDDENLY switched off. I thought "hmm, odd" and, being the idiot i am, did not check for any kind of overheating before switching the computer back on. So i switched it back on for a couple of seconds, only to hear a horrible noise (god knows where that came from). Of course I then instantly tried to turn the computer off by holding the power switch, sadly nothing happened (motherboard didnt respond) .
And so i had to turn the PC off at the switch. I new something was seriously wrong at this point, and so i pulled the case side off and checked each and every heat sinked chip for overheating of any sort. Of course im not a human thermometer but after feeling each one i found that the Processor seemed to be at normal running temperature, as well as the RAM and graphics card sinks (the PSU was also fine). I then decided to feel the rather large goldlooking "MSI" heatsink on the motherboard...
That thing was seriously hot!!!!!
And so i left the PC for about half an hour to fully cool down. I now turn my PC on and all i get is a flashing power LED, on and off every second or so (obviously the motherboard is well and truly dead now). So, three questions,
1) I take it the motherboard is the device at fault?
2) Do you think any other components may have been broken whilst the board overheated? (i just dont want to get a new motherboard replacement and find that my pc still doesnt work, or even worse, my new motherboard dies) .
3) Has this happened to anyone else?
If you managed to read to the bottom of this post CONGRATS! If you manage to reply then
THANKYOU VERY MUCH

Tried to bare boning with less hardware such as CPU+heatsink+vga+1*ram+good psu+kb+mouse. outside of casing and see any booting or not?
Well ive tried booting the motherboard just connected to the PSU, front panel (power LED, speaker and such) and processor (and fan). That gave me the flashing LED still . From my experience with other motherboards you can boot them with nothing in and still acheive beeps and such. Really the CPU fan should whirr in this scenario if it works, but it doesnt . I cant be overloading either PSU with this setup can I ??!

Completely random restarts (windows + linux)

Hey,
I put together a system (see sig) for a friend, anyway they started complaining about random restarts using winxp (with or without either service pack). Cutting a long story short, we RMA'd the motherboard, got a replacement, and the problem persisted.
Basically this is a list of things that has been observed to happen
1) Randomly reboots during winxp install (not connected to the internet, harddrive virus free did a complete scan and alternated b/n linux / windows installs, ie filesystem changed -> no virus)
2) Reboots under windows randomly, can be when surfing the net, ripping cds (this is the best test to make it happen), or just sitting idle (went to get a drink and it had done it). I tried to disable the "Automatic restart on fatal error" in the advanced settings thing, that did nothing, so im fairly certain that its a hardware issue after that.
3) Reboots during Gentoo Install (I figured I should stress test it), the reboots occur at different places depending on the settings changed, and detailed below, but inevitably it always reboots.
4) Occasionally winxp will fail to load, or givea a BSOD before rebooting, but this has happened maybe 5 times in hundreds of random restarts, the error messages are not in reference to anything in particular, nor could I garuntee the ability to get a copy of one to show you.
I spent most of yesterday digging around these forums reading suggestions etc...
The following is a list (i took notes) of what I have tried (this is long I know, im sorry)
1) Different PSU
Originally the PSU was the stock standard that came with the sonata http://www.antec.com/specs/true380_spe.html which at 380W seemed a little low (this was before reading forum posts), so replaced it with the one in the sig -- Not a PSU problem.
2) Different RAM
Figured since a second replacement board had the same problem it could be the RAM, tried RAM from my machine which I know is working perfectly, reboot as normal. Hmm so I did a memtest86 scan on the memory left it running 48hrs, that lets memtest86 loop about 7 times (for anyone interested) there was not a single error. -- Not a RAM defect.
Started reading forums here
3) Different Harddrive / Optical Drive
Tried a 120G sata maxtor drive (which I know works), reboots persisted.
Tried a DVD-ROM, from my machine, reboots persisted.
4) Measured the voltage with multimeter, all voltages were within 1% of the spec.
5) Put some thermal (arctic silver 5) compound on the cpu / heatsink, but the temperature under stress test never goes above 51 degrees anyway. Not at all out side the operational conditions for a P4 3.0.
6) Ram Timings / placement
If I leave as SPD, reboots occur more quickly, setting timings to 2.5-3-3-7 burst 8 gives me longer until the reboot occurs, however it still eventually occurs. I have tried running the ram in single channel mode (with both sticks in the same channel), dual channel mode 1 3 and 2 4 have been tested, and by only having one stick in at a time (
7) Ram voltage
I kept alternating b/n SPD and the above timings as I moved the RAM voltage 2.60 - 2.65 - 2.70 - 2.75 (I haven't gone any higher yet as thats the red zone, ie 2.80), the best times I experienced for a gentoo install were with 2.70 / 2.75 however after 20 to 25 minutes of compiling the machine restarts. I couldnt get the machine to restart ripping cds on this setting, but thats probably because I lost interest in ripping over and over again after the 5th time, I did get to 10th rip once, only to have it restart.
8) Clock Frequencies
Tried setting FSB to 201 (as some threads recommend), didnt help. Tried setting RAM speed at 266, 333, 400, and auto, the lower the speed the longer until a reboot, but only a minute or two is gained by 266 over 400. All this is done on the NORMAL (meaning SLOW on older boards) setting.
10) Video card
Originally there was just some old PCI card I had laying around in the machine (lack of money), however now (see sig), either way reboots occured, the video card was my 3rd suspect, motherboard, ram, video, psu, .... etc...
Thats it.
Now, I saw some people commenting (when I was reading the threads) that they wondered if this batch of boards was bodgey, no one seemed to want to agree, however after trying suggestions from over 100 threads (do a search for random reboot if you dont believe me) and not actually getting any success, and having had this happen over TWO of the SAME board, im really beginning to think that is the case. Some of the search results were PSU based, granted, so lets knock off 50% that leaves about 50 cases of this incident which haven't actually been resolved.
Im not playing blame game, it just seems very likely to me, but if someone gives me a solution that works, ill appologise profusely, and go and buy the MSI K8N Neo2 Platinum that ive been wanting -- but to scared from this situation, to actually buy.
This problem is remarkably similar to Random PC reboot this, except im not able to actually produce the windows errors as noted at the top.
So... Please HELP !!!!!

1st of all, kudos to you mate, now this is the proper way to ask for help!
but looks like you've tried everything other than hitting it with great force with a piece of 4 by2.
only thing i can ask is if you've tried increasing the vAGP in bios, this doesnt really increase the voltage to your agp (well, it does) but more to the point, it increases the voltage to the motherboard chipset. you've mentioned that youve put as5 on the cpu, it might be worth trying a clean and application under the northbridge too (though they do coat it with some cr@p so much its a bit of work sometimes getting it all off)..
another thing, though this shouldnt help, is to try increasing the vCore to the cpu just a tad, most intel boards' voltages vary a fair bit, some say its due to a special functionalities withing the processor itself, but most say that this hasnt been implemented.
other than that, best of luck to ya
p.s. or you could go get a cheap 865 board as a replacement, i wouldnt upgrade to a64 yet with nforce4 (nvidia) + xpress200 (ati) mobos just around the corner as well as 90nm a64 processors with sse3 instuctions too

System will not boot up

MB: KT6 Delta-LSR
CPU: XP2500 Barton
GFX: Asus V9520 Magic/T 128mb
RAM: 1028 pc3200 ddr400 (2x512) Geil Branded
HDD: Maxtor 40GB 2mb Buffer
Put it all together formatted the HDD, installed windows, network was working perfectly. (on ASUS via600 board)
Next day turn it on and nothing, zilch not even a flashing cursor top left of screen, dont even boot to DOS. screen is completely blank.
Tested CPU, GFX, RAM and PSU in another base unit and they work fine, yet put them all together and nothing.
1st I thought it was the mainboard so I sent the ASUS board back and ordered the KT6 Delta nice looking board. But still exactly the same problem.
Lights on case are lit all fans are turning ect yet still the system will not boot up i dont even get a flashing cursor top right of my screen.
There is no light with this mainboard for some reason.
All components work when fitted to another mainboard in a different case.
NB: one thing I have noticed is that there are two power sockets on this board,
1. The usual 20 pin socket (which I am connected to)
2. A 4 pin socket near to the CPU (whilst my PSU has a plug that will fit this sockect also, I am unsure as to connect instead of/as well as or leave unplugged.

Like I have stated before, it is the compatibility issue related towards your chip fsb and your memory fsb. I know that not everyone has money to go buy another stick of memory, I don't. But maybe you could exchange from the place you bought and say that it was a mistake? The cheapest route without getting the fsb chip to match the fsb of the memory stick is to get PC2700 memory. Have you tried going for this yet? I'm sure that your motherboard may not be shot, my board didn't get shot after trying to the two different fsb. You have to understand, motherboards are picky when it comes to running the hardware. If there is a conflict, it won't run right, I could run at a lower fsb and get it to work fine, but it wasn't at it's full potential, and I wasn't going to waste my time trying to find the fsb that would work correctly. So, I just let my friend have the stick back. This is why I'm asking you to try a lower speed stick of memory, because I have experienced this. But so far you haven't even seemed to notice my replies, could you take a quick overview of what I have said? Sorry if I come off as rude, just I am taking the time to write these replies and really am trying to help from my knowledge base. I have experienced this type of problem of what you are talking about personally.
Ok, so maybe I might not know it all, seeing that other people replying here have the same mb spec and chip fsb and memory like your trying to run, they might know more when it comes to that area for sure, just I didn't have luck trying to run a faster stick of memory compared to my chip, even though my board could run it, I couldn't get it to work, at all. I would just get a black screen, I thought I shot my GPU. Then I reset CMOS and the bios would flash, then when it would start pulling from harddrive, boom, black screen again. I had my friend tinker with my volt. to the right volts of the memory stick, still couldn't get nothing. This is why I am a little skeptical about you being able to run it at all in the long run. Hopefully you can find a way, maybe it is your manufacturer of your stick, but my conclusion is, if it isn't going to work with one, or two of same speed, try lowering it. Like I said, I tried it on this setup right now, and I didn't have to replace the chip or mobo, or gpu, so those should be fine.

What's wrong with KM4AM-V ?

To making an upgrade of my old system, I bought a motherboard KM4AM-V (KM400A), a Sempron XP 2400+ (socket A), 256 MB DDR 333 Mhz, and a new cabinet 350 dr-a235atx (Foxconn for P4 ... what does it mean? Is that for Intel?) that I discovered it is without Power-Led for JFP1.
I assembled a minimal configuration, just to try the new material: mainboard, memories, processor and hard-disk (all in the new case).
The results? If I insert the plug (without pushing power botton) I hear a whistle that stops only removing the plug. If I push the power nothing happens, even front leds remain turned off.
All that I did:
-   I connected power supply to the hard disk, and then the HDD wire to connector IDE1.
-   I fixed Sempron, Cooler Master’ set and the relative plug in FANCPU1.
-   I set up memories in DIMM1.
-   I did not touch SW1/SW2 (so FSB remains 133 Mhz).
-   In JUSB1, I connected the USB2 frontpanel cable.
-   I connected the relative wires in connectors JPW1 and CONN1.
-   In JFP1 I put : a) DOWN: HDD-LED (respecting colors: white on white, red on red), RESET-SWITCH (no indication about color disposition, so I oriented it like Hdd-led); b) UP: 2 pins POWER- LED and POWER-SWITCH (respecting colors).
-   In JFP2 I put: a) UP: SPEAKER (no indication about color disposition. I oriented it like others in JFP1); DOWN I did not put nothing because like I just said, the case doesn’t have the 3 pins POWER- LED, but in the same manual’s page (9) is write “JFP1 is compliant with Intel front Panel I/O Connectivity Design Guide”.
So, what’s going on? Is the cabinet or what else?
I cannot try these things in another pc because my old case is not compatibile with this new mobo, and my old mobo cannot support Sempron.
Ehm, I am a complete amatour in this things like in English Language, so please, speak easy.

I have just try with a minimal configuration, and every time I remove something more. At the end were remained only processor (Duron and Sempron, I tryed both), memories and wire CONN1 (no 4 pin ATX, no front panel wire, harddisk ... nothing!).
I will try without memories ... Will it be possible without CPU?
The surface was cabinet, but lay down ... I mean flat. The only way for don't have that whistle with PC plug inserted, and back cabinet switch ON, is don't insert Power Supply wire (CONN1).
"look in your manual for the JFP1 header pin layout - you can use a small flat blade screwdriver to short (or "jumpstart" as i refer to it ) the pins for PWR-SW to start the board." I will try, thanks.

lara, i think you need to establish exactly where this "whistle" is coming from.
strip everything out of the case, and put the mobo on a flat surface, preferably on a large anti-static bag, then connect basic components to it: CPU, RAM and PSU. look in your manual for the JFP1 header pin layout - you can use a small flat blade screwdriver to short (or "jumpstart" as i refer to it ) the pins for PWR-SW to start the board. listen carefully to hear where the whistling is coming from (from onboard buzzer?) - but don't unplug or reconnect the JPWR1 4pin plug while board is powered on!

MSI 790XT-G45

I got a problem, I can't set the bios to more then 240 fsb without it going black and refuses to start.
The OC switch is off since I want to reach more then 20% OC with my AMD Phenom x4 9550 CPU
I cant get higher? Or can I change some setting to let go of the cap?
Got a good cooler so dont worry about that!

H55m-E23 onboard lan doesnt work

i have an h55m-e23 mother board and the on board LAN stop working after 12 hrs. id looked in the bios to make sure that it was enabled and it was. i also tried to reinstall the drivers for it but it said that the device can not be found. is there anything else i could try.
my computer specs are as followed:
atx power up mid tower case
Intel i3-540 (3.6ghz)
4GB ddr3 ram
450w PSU
msi h55m-e23 mobo

When you said the LAN stopped working, does the LEDs on the LAN port still blinks?
Is the Ethernet LAN Connection still detected in Network connections? How about Device Manager, is the LAN chip being detected?

K7n2d Ram or Psu?
