I have an Alienware M17x. It's a powerful laptop with an Intel Core 2 Extreme Quad QX9300 processor, 8GB DDR3 Primary Memory, 2 Nvidia 280m graphic cards in Hybrid SLI configuration. So rarely, new games don't give me a problem with lag. About a week ago, it starting causing some problems. The games randomly freeze for a few seconds, if i was walking forward, it wouldnt stop when i let go for a few seconds..sometimes it would be fine..when i steer a car, it sometimes doesnt stop when i stop, shooting a gun. I also noticed while im typing this very message, the letters freeze and its like im not typing but the cursor blinks like im not typing so its not only in games, but the whole OS. If the only way is to re-install vista then i will but if this can be avoided, it would be exceptionally helpful. Its never done this before and it's a really irritating problem. Any help would be much appreciated. Thank you.
