As 1st RHA said, Have you got another you can try and also is it plugged in the right place as the mouse and keyboard are the same. Have a look at mouse in control panel see if you can find anything there.
I posted this message for a friend,and I tried a serial mouse and it works ok,but have found another problem one of my usb ports it does'nt detect the scanner,I plugged the scanner into another usb port,and it worked ok,there is some other problems that still need to be sorted,thanks to all for the info
tsham, one usb port working and one not working sounds like a harware problem. If the usb port is on the motherboard it could be the usb chip or a connector problem. If the usb is on a bracket it could also be the cable from the bracket to the motherboard not connecting properly. If neither of these works then you may need a pci usb adapter to get more usb ports. What motherboard does your friend have?
I've not had a chance to look at the motherboard,there is a few other problems with my friends pc,apart from the mouse prob,one cd-rom drive the the drive keeps opening and closing,we have to keep pressing on it to make stop,when he starts defrag, defraging c drive takes ages,(the drive is 20gig) to complete (hours),the origanal problem was a noisey fan,and since that his probs started,another friend of mine is going try and sort it out. thanks again for the replies
