Hey i just upgraded to a pentium 4 3.0 Ghz as some of you know. but on every game i have played so far i get either: Game freezes then returns upon black screen but i can still shoot, walk, ect. Monitor shuts off in the middle of a game but the pc remains on but unresponsive. never had this problem before realy it might be my grpahics adaptor im not sure. i have an ATI Radoen 9600xt 256mb
