Hi, at first I thought this might be virus related. I went through with help from Howard_Hopkinso, and removed all virus' and malware. But my problem persists. I have an Alienware Area 51 m7700, 120 Gig HD, 3 Gig memory, 3.8 GHz Pentium 4 HT duo processor. NVIDIA GeForce Go 6800 Ultra. What happens is when i try and playing a source game for little while the screen goes black, sound skips, but the laptop still runs. Also happens when i click on certain internet links. I assume that i need updated drivers, which i did. but that didn't work either. I am lost, any help would be greatly appreciated.
