BSOD + visual anomalies + atikmpag.sys error Hi all, could you please help me with my issue? I searched the web for hours but cannot find a definite/most possible reason (hardware? driver?) I'm about to buy a new videocard this afternoon but want to avoid it if it is not definitely a hardware fault What happened: - PC crashed in a game, textures and models went all over the place and performance slowly slowed down (cursor+response). Could not quit or Ctrl+Alt+Del either. Had to hard shut down with the PC switch. - Booting up.. Gives visual anomalies right before BIOS onwards: weird patterns (like when a monitor cable is loose). - I have dual boot, Vista and Win 7 x64 a) Win 7: Gets to Win loading screen but the logo stops animating then gives BSOD : b) Vista: Appears to load but gives only a cursor and a black screen. Runs for minutes like this (haven't tested longer). I cannot update a driver etc as I cannot get there. I've not yet tried Safe Mode as I'm at work I'm also quite happy to buy a new card if it's most likely a hardware problem. My question is, could it be a driver problem if neither OS loads? Any help would be appreciated ** UPDATE: atikmpag.sys - was a typo the video card is ATI HD 4850 - I took it out and cleaned it thoroughly, I suspect it could have been overheated easily+ PC sits by the window. My rig is a 3y old setup, I have not updated any hardware for 2 years, no driver update etc either in recent days.
