OK, so I will play a computer game, Counter Strike: Source for example. Everything will be smooth, and great. Then maybe 10 minutes after launching it, the game will lag, and the movements will be jerky, which is really hard to aim with. Right now I Counter Strike: Source, Red Orchestra, The Ship, Dark Messiah, Half Life 2: Death match, and Guild Wars on my computer. Now before I used to have a lot more on, without any problems. I don't have any virus's or spyware or adware to my knowledge. I guess I'll post my rig: Manufacturer: Dell Inc.
