usb stopped working

Hi all, have a problem with usb drivers according to my control panel which says it is fixing the issue and then tells me to reboot but it is not fixed. Keyboard lights up on start but when the first blue window appears it goes off. I can get into the bios ok and the keyboard works there. only one port is working (USB3). as my mouse and keyboard are usb and there is no PS2 port i am kinda cactus at the moment. Been searching for usb drivers for win 10 but not having any luck. Everything was working fine since November until yesterday. would appreciate any help. Regards Alec

Try sfc /scannow (run elevated command prompt)
