USB ports not working

I plugged in my husband’s Ipod to my 2.0 USB the other day and it wouldn’t do anything. The Ipod froze up and it gave me a power surge error message. I reset the port but then my mouse (USB) quit working after that. Nothing else that runs off of a USB works either. I have tried updating drivers and uninstalling/reinstalling. The USB’s show up fine with “no problems” but when I plug anything into any of them it still gives me a Power surge error message. I am to the point I’m ready to reformat the whole computer! Can someone please help!? I am frustrated and exasperated. Any help would be totally appreciated.
