Hi,
Since I installed win 7 ultimate x86 I started having troubles with my games. All games that I've been playing have tendency to crash. There is no set time, sometimes it's 3 hours, sometims one and sometimes there's a crash after 5 minutes. The game just shut itself down and message "program has stopped working" with the close program button appears. No other error explanation or anything. Games that I've had trouble with up until now are: The Lord of the Rings Online, Silent hunter 3, Mass Effect 2, NBA 2k10 and most recently (playing it at the moment) Dragon Age Origins with the Awakening expansion. I've tried reinstalling the system and installing the newest display drivers, but it didn't seem to help.
Can anyone give me any advice on this please?
P.S. I never had any BSOD or machine reboots, just game crash with "program has stopped working" message, so I don't know if there is any dump file or something that I should post here.
