basically it started about a month ago my computer started crashin during battlefield 2, which i had been playin faultlessly since its release, other games such as call of duty,united offensive and command and conquer generals all seem to crash back to the desktop within 20mins of gamin, tho only ones that dont crash are half life 2 and worms armagedon so im thinkin its not a graphics card problem.now let me give u the lowdown of what ive done so far:
#i have downloaded all the latest drivers, catalysts etc for cards and chipsets alike, all windows xp updated
#have checked all fans are working, and processor temp, which is fine(even opened up side and stuck massive fan next to it but still crashed)
#recently installed xp pro over my xp home in an attempt to restore any corrupt windows files, only to be met with blue screen of death but eventually managed to get it installed properly
#have ran a 6 hour memtest and that was fine
#have scanned my registry with cc cleaner
since then the games still crash as normal, any windows applications dont recognise that i have a cd writer even tho itunes will happily burn a cd (imapi cd-COM burning service is set to automatic and on too). occasionally windows media will crash. my computer never shuts down fully ever, u can hear things stop workin but it will stay on the blue 'windows is shutting down' screen and bascially im pissed off, asked loads of people and no joy!!. hope u can help.
