usb port does not work

[blindsleeper]

Hello,

I have the following problem, some time ago I took my PC to repair and asked that I activated my usb ports on the front (two).
Subsequently by problems of viruses etc., I restore my computer to occupy restoration windows XP disc that came with the computer, and since then the front USB ports were defused, only behind which are two are operational, how I enable again the two front ports?

Good.

I believe that no virus can disable ports front and rear not.
The USB ports operate or do not work, this problems is rarely if some work and others do not.

This happened when I called the representative of the brand of PC and told me that we should enter the bios to fix the problem, unfortunately I am not having this number. Other thing, when I bought the computer came with front ports are disabled and I particularly asked that the trigger, so good until they Is there may be a problem where program could have been turned off, or this is a physical activation and that "the cables were disconnected?
greetings
