Have a dell optiplex 320 that was infected by the FBI virus. Have been able to clean it up; however, the USB ports will not work. The system will not accept PS2 as it only has USB. After it boots to windows xp I can see everything on the desktop but I cannot get the mouse or keyboard to work. I have tried going into safe mode but have the same issues. The keyboard works in bios. tried other usb keyboards and mice with same results. any ideas on how I can fix this.
thanks in advance!
