Keyboard and mouse only work in setup

Hello!

I’m trying to fix a f****d up computer but I’m stuck. The thing was I uninstalled Novell Networks something and then I couldn’t log in. Then I followed some advice to change the registry (NWGina.dll to MSGina.dll) but then I couldn’t remember the admin password. The next time I booted the comp the keyboard and mouse didn’t work (at win login screen). They only work in BIOS and in Safe Mode Command Line and with UltimateBootCD and such…

I have run some scans for adware and viruses but none was found.

Any advice?

Thank you!
