USB drivers or you're running to many USB's and things like mouse and keyboard and your power supply can't handle it. Especially if your computer has lights, e.g. my mouse and keyboard have neon glows and shit^ - I had to update most of the things under "Universal Serial Bus Controller" then everything decided it would work after it. Could just be something to do with your ports too.. if you've bent a USB port it might not be fitting in properly.
Commenting because this really annoyed me for nearly a month and I literally had to force myself to step outside into the world because the PC wasn't playable^
the port was bent a bit, i had to jiggle the usb in , but it works now.
