I have a MSI GX623 notebook with Mobility HD4670 GPU, 512MB. Game is running fine on both medium and low settings, no fps drop or whatever, but for some reason, at random time intervals (from 2 minutes to few hours) screen goes black, sound plays for a while and then starts looping a bit of it. Only notebook restart is working.
Any help regarding this problem is very appreciated. Also please note, that I have 13.1 Catalyst, as well as latest game and Windows 7 updates installed. Other games (including WoW and Diablo 3) are working fine even with many background programs running. Hardware failure is also unlikely.
