Keyboard and mouse doesn't work after driver repair  

My boss bought a new HP tower after our old one ran out of space. I plugged it in and everything worked until I realised the scanner didn't work. I downloaded a driver but it still didnt activate the scanner. So I looked at the driver repair discs that came with the tower. I installed that thinking it would repair the scanner driver and when I logged back in, the keyboard or mouse USB didnt work. I hope I didn't screw up anything. The keyboard works in BIOS. My boss doesn't know and I would like to get this repaired without bringing anyone in. HELP! Im on Windows 7.

Sounds like the repair fudged the USB drivers. Have you tried starting windows in safe mode?

Just rollback the Driver,
If that doesnt work, use your latest restore point.

Hi all, I told my boss and he doesn't want to re-install Windows 7. Nothing else worked. So HP will be coming out to fix the tower. thank you for your input.
