Thank you. I had tried in safe mode, with no luck. The owners of the computer took it to be repaired to be told it was unrepairable
So I didn't get a chance to try anything else.
That should not be true, if the keyboard works in the BIOS, means the physical USB ports are just fine. Re-installing or maybe even repairing Windows should have fixed this. It may not be fixable with the current OS installation, but there is no reason why a re-installation of Windows would not fix this.
