What is wrong when the mouse doesn't movAfter about 10 or 15 minutee the cursor?

Question

I have checked the connection. After about 10 to 15 minutes the cursor just freezes. I can turn the computer off for a few minutes and then it will move for awhile.

Answer 1

Is the entire computer locking up or just the mouse?

If the keyboard is also locked up, it could be that your computer is overheating, or you have a bad chip.

If it's just a problem with the mouse, then I would try a different mouse. A new mouse isn't very expensive, so I would try replacing the mouse before you spend a lot on other repairs.
