Hi currently I'm using a msi 970a g43 mobo and I had to restart it by hold the power button cause it was hanging in the shut off screen but now when I turn on the USB keyboard wont power nor will the mouse which it has always done this since I've had it but now my pc needs me to use the keyboard to select an option to boot up and it doesn't have a count down so it's stuck there until I can get my board to work. Can someone please help me please, I can use my pc until then! All help is appreciated thanks in advance!
