i have a pc on xp, when i boot up all seems ok bar the mouse cursor not moving. tried the mouse on my lap top and its fine. any help on this would be fine.

Is it a wireless or wired mouse? USB or PS2?

wired

Reboot pc after you remove and replace mouse in socket

If it's USB try an alternative port, preferably one on the back of the unit.

If it's PS/2 it needs to be in the green or mouse PS/2 port.
