My mouse track keeps jumping around and it slows down my computer and also zooms in webpages randomly. I've tried diagnostics and nothing came up. Can someone help me?
When I use a usb mouse it works better for a bit and then goes back to the same thing. It's very frustrating and hard to use my computer. I also just got a new hard-drive installed about a month ago and it was like this before the hard-drive as well.
