Win98 doesn't boot after removing a USB mouse

[EvilHorace]

I've tryed posting this elsewhere but havent received a solution yet. My main server PC (about 1 yr old, built by me) dual boots Win98SE and Win2K. A while back I unplugged my Logitech optical USB mouse and tryed my older Microsoft balled mouse instead trying to see if that'd make a difference with a SS mouse movement problem.
After unplugging the Optical mouse, it wouldn't boot Win98 anymore. As it loads the desktop with drivers, programs, etc, it then just re-boots and does this everytime. I added no new software, hardware and didn't change anything in the bios.
The same PC boots, runs Win2K just fine with or without that Optical mouse.

In my attempts to fix this, I removed the Optical mouse from device manager (safe mode) but it makes no difference. I can boot Win98 in safe mode but I see no yellow !s or anything indicating a problem with any device.

Does anyone here have any ideas how I can save the Win98 partition (OS)? Can I re-install it over the existing install without being able to first boot the OS normally?

I do not want to format again but I'd still like Win98 to work again if possible.

I can't seem to do much in safe mode (like install drivers off a cd for example) as the cd-rom drives are inop in safe mode.

Did the USB mouse come with drivers? Maybe you need to unistall those (you may need to delete some keys in the registry as well). I don't know if this will help any but; boot into command promt only then run "scanreg /fix".
