recently bought IBM usb keyboard (with 2 onboard usb ports). plugged for first time and was fine. restarted PC thge next day, and got error message saying a USB device was malfunctioning. unplugged and replugged all usb hardware- the malf. device was the keyboard. tried restating pc again- KB was now dead. not only that- the keyboard entry was now missing from the list in device manager. tried plugging in my old usb keyboard and that would not be recognised either. cant do a repair from windows CD as cant type the serial key! KB doesn't work if restarting and trying to get into bios either. PC has a ABIT motherboard with all USB ports so can't even plug in a PS2 kbd! any ideas?
