Ok so I have an alienware 7700 that has a geforce go 6800 ultra, an intell 560 3.6ghts processor and two gigs of ram. Games run completely smooth then I hear the audio blurb and the screen lags and I have lag for around five min then it does the samething and it is crystal clear and so on. I think it may be getting worse however. I have updated drivers, deleted temp files, defraged, ran numerous virus/spyware programs, changed video settings, had my comp guy look at it and I cant seem to find the problem. What is wierd is that I ran 3D mark (a graphics testing thing) and there was no prob at all. Just when I play games. Also when it gets laggy my ping does not go down. It is usually around 85. Can anyone help?!
