Hi, my mouse and keyboard were working fine until yesterday when I booted up my PC they didn't work. I have unplugged all other usb devices but my mouse and keyboard and now I can get into the bios. Legacy USB is enabled but when I get into typing my password on windows startup, my mouse and keyboard won't work. I've tried all usb ports in my pc but still no luck. I tried my mouse and keyboard in another pc and they work fine. Any ideas? Thanks
