If I leave the computer sit for a bit (hour or so) the screen will go black It seems to randomly BSOD on the internet as well. The computer is clean as far as spyware/virus goes. I have updated the NIC drivers, updated flash and java, all windows updates, turned off screensaver, sleep mode, and hibernation. When I looked at the minidumps, it showed it crashing on an Avast file. So I uninstalled Avast and installed AVG. Then the crash showed it crashing on an AVG file. I'm thinking maybe CPU or Mobo. The mobo caps look fine. Please help!! Minidumped zipped: http://download.yousendit.com/BF3972172DA4B937 I have also run memtest overnight and run DFT and Seagate's HD Test, all passed. Tried switching out CPU's. Got same error. Also got 0x7E.
