No mouse

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?

Sounds like a resource conflict within windows doesnt it?

Is this a serial mouse? If so, then yeah, it sounds like a resource conflict in Windows and dollars to donuts it's conflicting with the modem.

Yes it sounds like a conflict, except NO mouse will work. It's one of those little tiny standing on it's side type deals. It doesn't have a serial port at all, just ps/2 and USB and neither of them will see a mouse. The Ps/2 port will see a mouse just fine in dos however. To me it sounds like maybe a third party mouse driver got loaded and it's interfering with windows BUT.. nothing shows as being installed and it won't redetect the mouse even after reinstalling over the top. It also will not work in safe mode. But here is the kicker we got an optical PS/2 mouse to work during the installation of windows. Once it was installed No mouse. Nor would a standard PS/2 mouse work only an optical!

Thanks for the tries, anyone else?

During install windows uses a generic mouse driver. Sounds like some other mouse driver got installed someplace and is causing a conflict someplace. Try going to your device manager and manually changing the mouse driver to the generic one. Good luck!

Thanks tried that also... it was not loading vmm32.vxd correctly. I copied it from another computer and then I could get mouse in safe mode. I then found a ton of corruption in the system.ini and cleaned that out. Works good so far...

I've got a similar problem on an old POS running at a doctors office. I can get the mouse to work by shutting down and changing the port (this is w/USB mouse) then restart, but next reboot the mouse is gone.

I really didn't care too much about it because all they run on it is an old DOS program, but I'll try again with these suggestions.

Thanks...
