Motherboard Causing restarts

Recently my computer is constantly crashing under medium-high load.

Ive replaced the ram twice,(i got 1.5gb now, thats a plus)
bought a new harddrive
and my videocard/CPU are brand new.

I'm 98% sure its my motherboard now, because ive searched and other people with this same board are having the problems, but i couldnt find any solutions

Anyone here know what i could do?

Specs:
Amd athlon 64 3700+ 2.2ghz Venice core
Kingston pc2700, 1.5gb
Antec 500w PSU
Ati Radeon x800
Biostar geforce 6100-m9
 
Odd you havent consider it to be a possible Power supply problem...you will find Power supply problems to be much more prevelent than motherboard problems. Power supply problems are quite often the culprit in system crashing under high load. Unstable rails are not always obvious to the user at startup but are a disaster under load.
 
Thing is;
I just bought a brand new powersupply.

Before i had a 430w Powermax PSU. and i thought it didnt have enough power to run it.
So i went out and went for something brandname and reputable, an Antec 500w trupower thingy(Forget real name).

Everything was fine for about a few hours Then it started rebooting again.

And ever since then ive been dealing with this.

EDIT:
Here is the specific error i get

Error code 0000009c, parameter1 00000004, parameter2 80545ff0, parameter3 b2000000, parameter4 00070f0f.

1003, Error (1002, or 1003) I'll have to see when I get home.
 
Ka102,

It's unlikely the motherboard is the root cause of your crashes.

I did some quick cursory checking on the web. It looks like your error codes indicate you have a wrong hardware driver installed. But maybe you could look at the meaning of the error codes more carefully than I did, I only glanced quick.

So right away, I'd suspect you might have the wrong driver installed for your new video card.

Suggest you uninstall display driver & reinstall from CD that came with your video card, or download from ATI's web site.


IF that doesn't fix things, then . . .

You don't mention what diagnostic testing you may have run, so apologies if you've already done what I suggest here. This gauntlet of testing will help you make your rig stable. It requires lots of hours, but after, you're computer will be reliable, stable.

1) Recommend you start by testing you RAM. Download Memtest86 free from here and run it 25 passes with all your RAM sticks installed, which will take many hours. After 25 complete cycles of all its tests, you should see zero errors found.

2) If you do get RAM errors, then first retest each stick of RAM by itself, with other sticks removed. Isolate the bad stick. I see that Biostar has instructions on how to run just 1 stick of RAM here.

You can also try relaxing the bios timings for your RAM, then re-run 25 cycles of Memtest86 as above. If after that you still get erors, return the RAM to the seller under a warranty claim.

After RAM passes, then go on to these other stability tests:

3) Download OCCT version 0.91, available free from many web locations (you Google it).

Run OCCT 30 minutes. If it fails, then again go into bios and adjust settings, probably increase vcore a little. The reason for running OCCT is that it's maybe the best quick predictor of whether or not you'll be able to pass the more stringent, TRUE stability test, which is Prime95.

4) After you pass OCCT, then download Prime95 free from here.. Select Options / Torture Test / Blend and run that 24 hours.

If you passed OCCT but fail Prime95, you've got some tweaking to do in your bios settings.

P.S. Watch that your chipset and cpu temperatures don't get too high while testing!!!
 
What is the CPU core temp running under full load and idle? As a quick attempt to fix, try increasing your CPU core voltage and RAM voltage a little.

Since it may also be a device driver issue, does Device Manager show any problem devices? Are you using the integrated sound/video?
 
I have a problem here..

I downloaded speedfan and started OOCT but both say my CPU is running at 127C and hasnt moved up or down, but my bios say its at 40C

I dont know if i have a conflict with the programs or my bios is wrong

Is there another program i could use?

(Not using integrated video/audio)
Ati Radeon x800
Creative Live! 24bit LS
 
Several free ones are available. Here are 2 (plenty of others also exist):

1) I happen to prefer ITE Smart Guardian.
If you're running Windows XP then download the one in the 2nd horizontal blue box down from top of this web page.

2) Another is Everest Home Edition.
This was discontinued by Lavlays in Oct 2005 but can still be found on web download sites.


Also, it's recommended that you approach the whole shebang in a stepwise logical progression. In my opinion, you'll be better off testing your RAM with Memtest86 before OCCT, which is an overall system stability test. Once you know RAM is good, then on to other diagnostics.

Say you fail OCCT 30 minute test, then what? Cause of such a failure could be anything; defective RAM, cpu voltage, chipset voltage, other bios settings, etc. Beter to know the RAM is good first, so that can be eliminated as a possible cause.
 
Im sorry i had meant to say that i had previously tested my ram before posting here.


I was too busy being flustered over 127C

My ram was bought as a matched pair and has no errors.


EDIT:

ITE Smart Guardian is also giving me readings of 127C, I had called AMD technical support previously and the representative had said its impossible.

Im at a loss, but currently am downloading everest
 
Is there ANY chance you're reading it 127C when it's really 127F? Your 40 C bios reading sure seems to hint at that.

40C sounds about right for a Venice core. My Winchester core runs at 38C only because of good cooling, otherwise would be 52C at my overclock voltages.

127 F is 52.78 C, which is edging above the max limit of what's O.K. for a lower-voltage Venice, and could probably be reduced with a good aftermarket heatsink mounted with Arctic Silver 5 thermal grease.

126 C is a toasty 260.6 F, & if true your cpu is now useful only as a paper weight. So since you still can boot, the 127C can't be true.

I'm not sure where the actual flames begin.

I'd tend to believe your bios reading over the others. Good luck!


EDIT: I see that what I'd suspected is NOT the case based on your post above mine. We "cross-posted" so I hadn't seen that before. And yes, something sure does look wrong with that -12V reading.

Are the voltage readings that you pictured in ITE Smart Guardian holding steady, or are they fluctuating +/- as you watch it? If fluctuating a lot, then may indicate a bad PSU.

I can't diagnose the cause. Sorry. I hope a more knowledgable person will step in here to help you further.

Also, keep in mind that the error readings you initially posted seem to point to a problem with a hardware driver.
 
I had a mysterious reboot issue as well. It turned out to be Daemon Tools. If you have that installed, try removing it.
 
Well both Smart guardian AND speedfan are giving me the 3.39 volt on my -12v rail

But to me that seems a little fishy, should i even be able to boot?


Is there a way i could tell the voltages in my BIOS? my bios only displays +12v and +3
