you helped me with the Ham, so i'll help you with the computer. ;-)
IT's kind of like telling someone how to program an odd offset for a repeater in their Kenwood. you just kind of poke around till you get it. But i'll try my best...
When you first start the computer, there should be a prompt that says "press F? to enter setup". it usually F2, but some computers are different. From there, there will be a series of screens. You'll want to nose around and go to the one that says Bios or Chipset configuration. there should be a menu that says USB and it will either say Enabled or Disabled. Kick it to Enabled. Follow the instructions to Save and Exit(usually F11). And you should be good to go. IF you'd like, i could even give you a phone call and walk you through it. BIOS's can be tricky sometimes. Gimme a holler if you need more help!
