Keyboard & Mouse problem (urgent!)

I have a BIG problem, today I installed my SCSI-card for my CD-burner, after the installation the SCSI-card didn\'t work properly so I looked in the Device Manager and there I noticed that the following Devices was in conflict in some way: the SCSI-card, the gameport, PCI Management Bus, the Keyboard and System Devices> Motherboard Resources so I removed all the Devices from the Device Manager, but when I restarted my computer neither the keyboard or the mouse worked and windows doesn\'t start in normal mode, in Failsafe mode it starts but since the keyboard doesn\'t work I can\'t do anything!!! What should I do ? Do i have to reinstall Windows ?
