Hey I have the same GPU and CPU you have on a Gigabyte Z68 board and have/had the same problem. Powercolor just makes shitty GPU and/or bad compatibility with the Z68 boards.
What I did to fix the crashes was I downloaded LucidLogix Virtu and have my monitor plugged into the motherboard video output NOT the GPU video output. It never crashes anymore for the games I run and I get almost the same performance as if it was running straight off the GPU. But Virtu is a badass software basically it integrates your GPU and the Sandy Bridge HD video chip on your CPU..So if I am just web browsing it will run off the i5-2500K video and if I play games my GPU will do all the work.
And as a added bonus the Video Encoding performance of the i5-2500K or the Sandy Bridge video in particular, so when I want to convert my DVD movie into a mp4 it's like 50% faster than if I used just my Dedicated video card...Virtu only works for Z68 and the new Ivy Bridge motherboards by the ways.
If you found another way to fix your problem please let us know.
My GPU had completely crashed so I got it exchanged as it was covered by warranty...
after that it worked almost perfectly well, except for few days when it started crashing occasionally... that gave me a real scare!
I just removed re-installed my gpu and luckily its working gr8 ever since.
khmerog@ ur way of fixing the problem sounds pretty good.. I haven't tried it yet but will go for it if the crashing starts again... thnx for d info
