Mouse not working

Hi friends!

I have XP and USB mouse...
The problem is mouse not works.
I tried like..
1) Disconnect the mouse and put it in the 4 USB ports.
2) Checked for the drivers in Control Panel > Mouse.
3) Disconnect the mouse, Shut down the sytem, Connected it and then Booted the system

No way the mouse is working.

Please help me...TIA to all!

First of all check if your BIOS has USB mouse support or not!

Also send me screen shot of your device manager fully expanded. You can find it under Control Panel--> System --> Hardware --> Device Manager
