My specs are as follows:

ASUS A7N8X-X (1009 Rev)
Chieftec ATX 350W
AMD Athlon XP 2700+
2x256 MB DDR (333 MHz)
CHAINTECH GeForce FX 6800 128MB (Tweaked 71.20 drivers)
Realtek AC'97 onBoard
WD 80GB (7200rpm - 8MB cache) + WD 20 GB

What my problem is that while I run 3D games, the computer will lockup randomly.

At first the screen freezes but there is sound, after a while sound keeps repeating the last 100ms again and again, and after a while sound cuts up too. Nothing works, nor Ctrl-Alt-Del or any other combination. The computer just locks up and I have to reset.

Notice that nothing is overclocked.

At first I thought it was a problem with the memory, but MemTest86 gave me no errors.

Any ideas?

sounds like maybe something currupted your onboard sound drivers,try going into divice manager and disable the onboard sound (just as a test). if it works try updating the drivers and if none available roll back the drivers to previous version.had this happen with some games.asuming autoupdate is on it might have updated to newer drivers that are buggy.

Nope, the audio is not it. I tried disabling audio through the DevMgr but the crashes are still there... Any other ideas?

My PC is doing the EXACT same thing. My specs are as follows:

AMD Athlon 64 Bit processor
Radeon 9600 128MB
512 MB RAM
Windows XP

My PC has been doing this on and off for ALL 3-D Graphics games ranging from Morrowind, Everquest,and World of Warcraft.

sorry was gone to chicago for a couple days.just a thought,whats running in the back ground?like your av,anti-spyware anything like that?//////// try disabling av and or anything that isnt reqd.
just got back an hour ago and having first cup of coffee so typos might be frequent lol

Supertrucker

Nope, I close every single program that might interrupt... No AVs, firewalls or anything.

have you tried the nvidia reference drivers?might be chaintechs (tweaked drivers) are buggy?havent tried that board so not sure about the drivers stabilty

amd 64 3000 939 msi neo2 platinuim 1gig ddr 400 winxp

It's not exactly Chaintech's drivers (the tweaked ones), I'm currently using the XtremeG 75.90 ones (just installed them), which haven't been reported to cause any trouble. I'll try them, and if the problem is still there, I'll tell you.

I have the exact same problems, and my specs are as followed.

Motherboard -
Foxconn- NFUK8AA (nForce 4 Ultra Chipset)
HD - WD Raptor 74GB
CPU - AMD 3500+
GFX Card- 6600
PSU - 520 Watt
RAM - 2x 512 DDRRAM

Nothing is OC'ed so I cant use that excuse, and it cant be Overheating, because my comp runs like 25 Celcius on idle.

Just wondering, are your graphic cards PCIx16's?

Hope we/someone can find out the answer why this happens..

What games were you playing when they started crashing like this??

I've got through this problem... But I really, and I mean REALLY, don't know how! I am now using 75.90 drivers and the latest drivers for my on-board sound card. Best bet is that the udpate fixed the problems. But another thing, and it is a good shot to try, is that I installed and used Game XP.

Maybe you should try it too, I don't know. Google for it.

I am having the same problem.

System:
Motherboard: Abit AA8 Duramax
Processor: 3.4 ghz. pentium
Videocard: Radeon X800 XT 256 ram, PCI-Express
Soundcard: Audigy 2 ZS,
Ram: 1 gig DDR2

I am at my wit's end. I have updated my video, audio and motherboard's drivers. It freezes up anywhere between 3 minutes to an hour after I start playing. the symptoms:

Freeze, after a few seconds, image becomes extremely scrambled beyond recognition. Sound normally begins looping, then after a moment, cuts out to a loud screeching, still looping, static. I have tried everything {Even tech support.} and gotten no results. It's hard to get pleasure out of a game when it keeps cutting you out! If anyone figured out a means to solving this problem, {or even what the problem IS,} let me know.

Games I have experienced the freeze with: City of Heroes, Morrowind, Neverwinter nights, and a few more.
