I have a quirky hardware issue with my computer here at the office. The USB keyboard and mouse plugged into my Dell 1.7GHz P4 are initially recognized by the computer during startup (lights appear on num lock and I can enter BIOS setup), but once the flat screen monitor performs an auto adjust and Windows XP loads, I lose all functionality of both the USB keyboard and mouse. These same two pieces of equipment worked fine on the computer yesterday, but I had to move offices and disconnect and reconnect all the equipment to set up my new space. The only difference between yesterday and today is the flat screen monitor that I recently upgraded to. However, even when I unplug that and attempt a clean reboot, the problem with both the USB keyboard and mouse persists. Any help would be greatly appreciated.
