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.
