After running a clean-up utility on my older computer (700mhz Celeron) I rebooted and when Windows opened I had absolutely no use of my keyboard and mouse. The mouse is a Microsoft Optical and the keyboard is a Compaq. The mouse connects to the keyboard through a USB port, then the keyboard to the tower through another USB. I have tried connecting through one of the other USB ports, rebooting several times, and have even tried using a serial port adapter with no results. It simply will not recognize any USB hardware. The computer reboots normally but without any input device I can't start up in Safe Mode or even reformat the hard drive, for that matter.
Can anyone suggest a fix for this problem?
