A Strange Mouse Problem

I have a strange problem with an old Compaq Pentium 100mhz

I installed a network card into this computer and after turning the computer on again I found that the PS2 mouse was not working anymore.

I have tried everything to get the mouse working again such as:
* Removing the Network Card
* Trying a different mouse
* Different Drivers
* Also Windows doesn't recognise a serial mouse as well! When I attached a serial mouse, the mouse started working for about 2 seconds then stopped again
* I have also tried a dos driver for both the Serial and PS2 mice but to no avail
* Also, windows will detect a PS2 mouse port but will not recognise a mouse in the port

The comp is using Windows 95.
I don't think it has a virus because the comp didn't have any access to other sources where it may have gotten a virus (such as the Internet), between the period of time where the mouse worked and did not

Any ideas anyone?

At first, this looks like an IRQ conflict, but that should have been resolve by removing the new hardware. You could take a look in BIOS setup and look for anything about reserving IRQ for legacy devices. IRQ12 is normally used for the PS/2 mouse, so this should be reserved. You could perhaps try to reset the CMOS (or going to BIOS defaults) and see what happens. Make a note of hard drive parameters first, if there is no autodetect in this BIOS.

Thanks for responding, but I have already tried resetting the BIOS, and I couldn't find anything to do with reserving IRQs for legacy devices.

Any other ideas???

try restoring the system reg. files. start,run, type restore. could have damaged setup files while installing card. also check control panel, mouse icon for proper selection.
