So for a while now my computer would be perfectly fine but when i'm playing a game often it would have a huge lag spike for about 5 seconds to 1 minute and this lag spike is so bad that i get like 1-3 fps and my sound is all glitchy. But its only on games. I have managed to fix it on 2 games by updating my video driver or graphics driver or what ever it's called. But on every other game it still does this and its getting worse. I don't know how to check my computer stats but I can tell you its a windows 8.1 laptop please help
