My mouse will not work, I am using window xp. I have an arrow but it will not MOVE. It will work on other computer with no problem. It is an optical mouseYou may need to be more explicit!!!!

I DEDUCE that you have no mouse cursor on screen or - it will not move. But you say mouse works - on another machine?

So - what op system do you have, on what computer? Is this a new problem or old - does it tie in with recent changes?

Your question is as PRESENTED unanswerable really. Expand - fully.USB? Wireless? Optical? What OPERATING system? More information needed.My mouse will not work, I am using window xp.

If so....
Uninstall mouse through Device Manager, restart computer. It'll be automatically reinstalled.
If not, borrow PS/2 mouse, and see, if it works.Still a bit lacking on info!

OK so - optical mouse but - direct PS2 connection? - USB connection? or THRU an adaptor?

How long the problem?

Does it coincide with any other changes?

It's hard to establish what might be wrong without info - lots of it - probably more than you might think relevant. Even then no guarantee of a diagnosis and cure.



Per Broni - yeah - safe mode test would help tooActually, what surface is it on?
