secondly when im using the pc, the USB mouse frequently goes off and then switches back on after a few seconds! i tried the mouse on another pc and it was fine! BTW its a microsoft habu mouse and when it goes off all the lights on the mouse also go off.

Are you running in power saving mode? If so, goto control panel and change the plan settings. Choose advanced and disable USB selective suspend. Either that or choose balanced.

checked that, it was allready disabled.

Check for latest chipset drivers. Does the light going off & on correspond with wiggling the cable and connectors? Sometimes the cable on mice is loose or frayed, causing connection problems.

Do other USB devices do the same thing? What does the PC's event log say? Does the mouse do this in other ports, either on the back plate or on the motherboard USB headers?

another option:
Is it connected to your monitors hub? I've had issues in Vista whereby the monitor hubs would switch on/off for no reason, while using the PC.
