I have ran SFC /VERIFYONLY in admin mode, and it returned all files are good.
I also ran Memtest+ overnight, and no error at all.

The Event Viewer in Win7 is still completely worthless in searching for clues to problems.

Since the BSOD doesn't originate in the same file, and the errors are different, can I exclude bad hardware ? I have a dual boot system with XP, and there I haven't seen a BSOD in years, so that means memory and hardware are not at fault I think.

The problem is, the BSOD happen so random, one time while browsing with Firefox, the next time while doing nothing (return to my desk and see the BSOD occured while I was away).

I have the latest drivers for my ATI videocard, and a working driver (allthough these are very rare) for the Creative soundcard.
Hard drive error scans all turn out fine too.

I really don't know what to think about being the problem.

Thanks for the help JMH,

crossed fingers, but i didn't get a BSOD since, I have ran Memtest86+ from a floppy for a full night, and it said 0 errors.

Hope everything stays well now.
