I have a sony Vaio Laptop and the Ports and Coms have disappeared from my computer. I have tried to use my usb cords and I can no longer do so because there is no coms to place it to. The Ports are not even listed in the Hardware section of the computer.

Would anyone have any suggestions how to resolve this problem or why this would have happened. I contacted Sony and there suggestion was to reformat my computer. I did that but I didn't help the problem.
