Mouse pointer freeze up

Hi,
Does any one know what causes a USB 2.0 mouse pointer to freeze on the screen after boot up in Windows XP Pro, SP2.

This usually happens about every 2nd or 3rd boot up when installing new software or updates that requires a restart.

It normally does not happen after shutting down the computer at night & then restarting it again in the morning.

Thanks for any help.

 

Batteries

If you use a wireless mouse you should check the batteries in the mouse and in your keyboard.

 

Thanks Guys for the relies.

I do not have a wireles mouse.

I connected another USB mouse and rebooted several times without a problem.

Apparently the Dell mouse has gone bad.

Thanks for your help.
