I keep getting PFN_List_Corrupt BSOD with 0x0000004E. I've run memtest86+ for 2 days straight, no errors. I started getting this after playing a bit of far cry. This BSOD only happens when my computer gets to the log in screen. I can just restart my computer, and there'll be no more problems, but it's just annoying. I have updated all my drivers, ran a disk check without problems. Also set PF to 0, defragged, and then set it back to what it was before. The problem still persists. I never got this on this computer before, and I've had it for around a year. It just started happening recently.
