So I recently built a computer and installed Windows XP. I validated it and it ran fine for 3 weeks. Now when I boot it up there is a prompt that says I have 7 days to validate product and asks if I want to do it now. I hit yes and it brings me to my desktop and a prompt that says this product has already been validated. That is a pain but doesn't hinder me. However, now neither of my mice work. When I try them in other computers they work fine. When I plug it into my new computer it beeps and says new hardware, and the mouse is able to move for like 2 secs then freezes up. Could this have something to do with the whole validating thing. It is very frustrating. What can I do?
