I haven't worked on this one directly yet but I thought I'd get some ideas before I go...

I have a customer with a celeron 366 with an intel chipset ( not sure which one though ) and he said it was working fine until recently the mouse quit working. Windows98se will recognize a mouse but you can't do anything with it.

Things that have been tried ( though again not by me directly ):

1) uninstall mouse and let windows detect ( both in safe and normal mode )

2) USB mouse. USB enabled but no mouse.

3) Virus scan run

4) dos level mouse driver and dos game tried. mouse works fine.

5) dos level mouse driver in windows.. No mouse

6) Windows loaded over the top of itself still no mouse

Any ideas short of the old fdisk/format routine?
