The sad part is that I did extensive testing with Memtest earlier this year when I put this box together. I started with 4 GB and then went to 8GB. I had trouble with the second set of ram....that brought on the MEMTEST testing which helped me to find which sticks were bad. Everything was fine until a few days ago.

I'm going to pull all this ram and reseat and retest. It's hard to see why RAM would go bad. This is the RAM i'm using:

Good to hear! I lost weeks on a system the user swore went unstable w/o any changes. Only to try Memtest86 in desperation after several reinstalls of windows, bad cheap no-name RAM upgrade was culprit.

Could be, couldn't hurt to boot Memtest86+& do an overnight scan. Best test is card in another system. Thoughts would wander towards the PSU output vs. load also.

Trick I find with ATI drivers is the crash recovery trigger is too sensitive timing (timeout?) wise thus wants to reset even when the card may have to continued to respond, this for no other reason than loose timing caused by high video+cpu+hdd loads IMHO.

So even when they work they hickup more often then they should.

Actually, it sounds like bad RAM to me.

Thanks, I got it.

I used ATI Install Manger to remove the driver. Rebooted.

Then I removed the driver that was installed in Device Manager.

Then I used Driver Cleaner.net to remove all ATI drivers.

Rebooted.

Got GPU-Z running.

Now, the driver is back. I guess Win7 is reloading the driver.

I don't see anything strange here. GPU Temp is 41C, fan speed is 35%,
and the 3 GPU temps are 38.5 to 41C.

Yet, the problem persists. Even while typing this out...the screen
freezes, then the screen goes dark, then it returns with a message
saying that the video card driver failed and restarted. This just
started happening today.
