After running Windows update, none of my USB ports are working. The wired mouse and keyboard won't light up. However, when I do a hard reboot, they both light up, until Windows loads then they are dead.

I'm able to hit Del and enter the BIOS, but once I'm in, nothing works again. I know enough about computers to build one, but this is beyond me. How do I get into my registry or device manager if none of my peripherals work? I'm also using a USB Wifi dongle, and have no access to the router for a LAN connection.

    If the keyboard doesn't work in BIOS, it probably isn't a Windows Update issue. If you move the devices to different USB ports do they work?

  • I've tried all of the different ports with no luck.

  • Do you have a PS/2 mouse and keyboard lying around? If those work you can start making checks on your USB devices from within Windows. Mar 14, 2014 at 13:57
  • negative, I'll be picking up an adapter soon.

  • Well a Windows 7 would not effect them while in BIOS. So it wasn't the update that did this.

Here are possible solutions to try:

  1. In device manager uninstall every USB device and restart

  2. rollback the windows update

  3. boot with a live cd (e.g.: Ubuntu) to see if it a hardware issue or software.

In your case you'll have to find a PS2 keyboard. (If you still have this type of port.) If not you won't be able to check solutions 1 or 2.

  • tried a PS2 adapter, neither mouse nor keyboard worked. That tells me its not just the USB ports, but PS2 as well. I can't get into my system to trouble shoot. Your next solution was to boot with a live cd, like Ubuntu, right?
