ok so about a month ago i got a new vcard when my 8500gt died. the new card is a ati hd 4670, for 2 weeks it ran flawlessly without a hitch. then one day my screen blacked out and wouldnt come back on. i took the card out and reseated to no avail. did this for 2 hrs. finally gave up went to sleep. got up the next day said wth one more time. put it in and it worked no problem. so my comp ran for a bit and again same thing happened.
now im having the issue where my comp will run decently for awhile (unless i stress it with games for 6hrs), but when i shut it down, the video card doesnt wanna work for 8-10hrs after. and lately the system doesnt wanna start up until about that time as well. if i take the vcard out tho the system runs just fine, i even threw in my old card that is all fucked up and pixelated and it boots just fine and doesnt shut off. so im confused and looking for info. whats strange is after w/e time passes the comp starts up and runs fine unless i super video stress it for a bit then it'll go black screen and not work again for that time.
ive reseated all the power connections. i even took the dvdr off to see if that was using too much power or something.
reseated the ram
reseated and cleaned the card and updated the drivers.
any help is appreciated
