Recently I have bought Witcher 2 and wanted to play with high details. It turned out that my old PC was not good enough, so I decided to change video card and buy some more RAM. I bought additional 4GB RAM so that now i had 8. I learned that my Windows 7 32 bit has a RAM limit of 4GB so I installed a new version of Windows 7 Professional 64bit.
Now, everything works fine apart from the times when I am playing the game. From time to time there seems to be a problem with a video card. My screen blurs for a sec and then its back with game details gradually decreased and slowly coming back to the original high settings. This wouldn't be a problem, but most of the time, after the initial blur I simply get a warning on my screen "no signal detected" and my computer restarts (actually it has problems restarting and boots only after a while). I know that this is not an ordinary BSOD thread as I do not get the BSOD screen, but it reminds me the most of it.
Attached is what I get using SF Diagnostic Tool.
Can anybody help?
EDIT: This is what I get using WhoCrashed

Obviously I cannot update the driver because it is the latest one...
