The keyboard on my laptop was acting up so I took it out to clean it and see if some of the keys that weren't working would start working again. They didn't and so I need a new keyboard. However, the mouse started acting mad. It was way over the top sensitive. Anything it touched it would open up even with out a click. It just went mad and almost impossible to use. I did a system restore to try to get back to normality but now the mouse appears on the screen but it won't move at all. It's a compaq NW8240 laptop. Any idea?
