Friends PS2 mouse suddenly went erratic and then stopped working on his system (P111 550,256 ram, WinXP,32meg TNT2). I ran latest Nortons' virus check and other utilities-no faults detected. I tried a USB mouse it worked but the keyboard failed. I then tried a seriel mouse. Both it and the keyboard worked fine worked and has been working fine for the last two weeks. Any ideas? It's a Mystery to me!!

Strange but true, I've found that some PS2 mice have a mystery "static charge" buildup every now and then. To fix, you'll have to complete shut down, unplug the mouse, tap the plug on the desk a few times to clear the mystery "static charge", and reseat it. Boot back up. It should work normally.

We have it happen here quite often.. especially on PS2 mice.

*shrug* Go figure...

Thankyou for your responce.It is amazing at times how static charge can affect components buy not this time.

Have you tried another PS/2 mouse? Sometimes mice fail without any obvious reason.

If you've had problems with both the mouse and keyboard ports, my first thought is that the motherboard may be starting to fail.

Thanking you
After going through the process of elimination...it finally was the motherboard

You didn't say who the manufacturer of the mouse is. If it is more than a standard two button PS/2 mouse you might need to reload the device drivers for the mouse. I've had the same problem before and reloading the mouse drivers fixed it.

Well, if its an old mouse or a cheap-o mouse then it may just be bust. Check the cable cos that if its damaged it could be the cause. The port could be bust but usally you need to open the mouse, and clean it out, mouse ball and all. All sorts of stuff gets stuck in there....

Have you/he/she tried using the mouse on another computer?

This would help determine if it's the mouse or a more serious problem.

How about removing the mouse from the Device Manager and rebooting. Windows should then reinstall the mouse and hopefully use it.

Sounds like a bad motherboard to me. Did moving the mouse after it failed make any strange beeps from computer? From my experience in those cases (especially if kb works bad with ps/2 mouse) mb needs to be checked.

by hortonpj

Thank you for your interest
There were no beeps when removing mouse. I tried several mice......reloaded drivers and Win XP......change the MB al is OK

Thank you all for your interest and input. Finally it proved to be the motherboard after much trial and error. I tested the MB on the bench and it still played up. It is in the wheely bin now! My friend is very happy and finally I can get some peace.
