hey i need some help..my usb ports were workin just fine a minute ago and now they don't work at all so i looked in the device list and theres a little exclamation mark telling me that the drivers r corrupted. so how do i fix that. i uninstalled them and they didn't install correctly when windows reinstalled them. so im wondering do i have do repair windows with the windows CD. or is there anything else i can do. it says on my motherboard CD that if u have service pack 1 or higher it should already have the drivers. so my motherboard CD doesn't have the driver for it on it.
