USB ports not functioning

I'm using a laptop three year old Hel 80 from ibuypower, and I recently ran a kill disk because something was preventing me from opening a couple of programs. So I ran the kill disk, reformatted everything, and reinstalled all the drivers that came on a CD with the computer.

But now my USB ports don't work. I plug in my tablet, and if the tablet is getting power, there should be a light on it that shows up. No light. I plug in a flashdrive, one that lights up when it is functioning, and at first it will light up, but then nothing. There is no error message, no detection of any new driver or software.

OS: Windows XP Professional, SP2

Level of experience: intermediate enough to know to try to reinstall every single driver ever

When did the problem start: right after reformatting everything, which suggests driver error.

Troubleshooting steps: reinstalling all the drivers off of the driver CD that came with the computer.

Error messages that pop up: zip, nada, nothing. The flash drives don't even show up on the "My Computer" page.

So I guess what I want to know: is there a different driver out there for USB ports? Preferably something universal, because I don't even know what kind/brand of USB ports I have. Or if anyone has any other recommendations, that would be great, too.

Edit: Never mind! I went into the device manager, and uninstalled then reinstalled the drivers and that fixed it.
