I recently bought a used E-machine W3080 system model KM400-8325. Im running XP home. I was having system lockups so I updated my video driver, which is VIA/SEG UniCrome Graphics. I was trying to play some newer games and thought this might help.It did not . I ran several registry and disk cleaners and have worn my self out looking and reading on why this was happening. All the games I have say they will work with my system. Now it has Blue screened me with Bad_Pool_Header , Event ID's errors ,file problem with Win32k.sys. just to name a few. Is it bios???? I am in need of guidence. Any suggestions????
