A few days ago my browser would blink out black, then come back but frozen with an error message about something to do with video drivers. Now I'm getting blue screen after blue screen with different messages like "system service exception", "Bad Pool Headers", "PFN_LIST", and a few others. Re-installed 306.97 video drivers still getting bsod. The only other thing I could think of was my C: drive was almost full but I've deleted a bunch of things and now have over 800 free gigs on it, still bsod. I'm wondering if a full C drive would have corrupted anything? Probably should re-format though I just did it a month ago.. oh I turn of system restore so I go no back up.
