Windows 7: Random complete system freezes.. Frustrating.

Random complete system freezes.. Frustrating.

My system will randomly freeze and is completely unresponsive to any keyboard/mouse input. I have to either shut down the machine or hit the reset button.

Strangely, this never happens while gaming. I can game for hours and hours and have zero problems. The only time I get freezes are when my system is using low resources. Just browsing the web and such. Also strange is that it is very random. Sometimes I can have it happen many times one day, and other days it never happens once with significant web browsing and stuff.

It also only happens when I'm doing some sort of action.. For example clicking a button on a website, loading a youtube video, etc. It will never happen while completely IDLE.

I have formatted my system completely several times, all drivers up to date, BIOS flashed to latest, etc. I have been dealing with this problem for months and am coming here for help! At first I was thinking either memory or video card problem, but considering they do not fail stress tests and gaming is flawless, I can't understand how they would be the issue?

My CPU is overclocked, video cards are stock. I have run memtest, prime95, furmark and all have run without any system freezing, blue screens, etc.

I have attached my minidumps/perfmon/xml file in a .zip to this post.

OS: Windows 7 Ultimate x64
CPU: Intel i7-920 OC'ed to 3.4ghz
Video: 2x EVGA GTX480 SLi
Motherboard: EVGA x58 SLi
Sound Card: Creative Labs X-Fi ExtremeGamer
HDD: Intel X-25 80GB rev2

Thank you so much for your help!

Your Nvidia driver was involved in the crash(nvlddmkm.sys)

STOP 0x116: VIDEO_TDR_ERROR troubleshooting

- Stop any overclocking and reset your BIOS to default values
- Boot into safe mode with networking
- Uninstall the Nvidia drivers
- Use driver sweeper to remove leftover Nvidia display driver files Guru3D - Driver Sweeper
- Reboot in safe mode with networking

I wanted to wait awhile to make sure it wasn't a fluke. But so far, so good..

I didn't disable overclocking on my CPU, but I did do what you said about going into safe mode and using driver sweeper and installing latest drivers in safe mode..

So far not a single freeze..

What's strange to me is why installing the latest nVidia drivers on top of whatever is pre-packaged with Win7 causes hard locks? This has been going on for months with many different driver iterations so I know it's not one particular nVidia driver..

I would think installing the latest nvidia drivers after a fresh format would not cause any problems. <shrug>

Thanks again for the advice!
