For the most part ever since I got this laptop, every game I've played on it runs smooth and never chugged. Bioshock, Soulstorm, Mass Effect... But now with simple games like Lego Batman and Warhammer Online, occasionally every few minutes the game freezes for a brief moment then resumes. It normally wouldn't be that big of a deal but it's starting to happen more and more often. And in Warhammer it's happens randomly and when I'm in the middle of a scenario it usually gets me killed. I have 4GB of RAM so I think something's up, but a spyware scan came up with nothing.
