What happens right now is when I start my pc with installed drivers, screen goes black (after windows loading) and after 2-3 minutes I get BSOD with atikmdag.sys. (and sometimes atikmpag.sys) Safe mode works fine so there I can use driver sweeper to delete files so I can get back to "normal" windows and there uninstall rest. It started with 10.2 when I was playing games, screen went black occasionaly (not realy often) when I was quiting or alttabing so then I had to do hard reset. But on my last play I got some artifacts (little blue circles all over the screen) so I exit the game and *PUFF* black screen and windows didn't start to this day ;( And after this it happens with different drivers like 9.11 and 9.12. Spec: Vista 64bit SP2 c2q firstname.lastname@example.org Sapphire 4870X2 with Arctic Cooling Accelero Xtreme Asus Rampage Formula 2x 2GB DDR2 Kingston I kinda rulled out overheating because in idle it gets to 34'C and in stress to 48'C (and gpu was not o/c). Tried windows recovery from few days back, didnt help also read about one windows update that causes bsod but uninstalling didn't help :/ Installin just display drivers without ccc also no luck. any advice ?
