I recently got a new msi 970a-g46 motherboard and put together a new computer using my old hard drive. Problem is it isnt recognizing my usb mouse or keyboard. I also tried the ps2 port with an old keyboard and mouse but only the keyboard will work. Ive tried 2 different mice and they both dont work. I need a mouse to reinstall windows. I dont know what the problem is... any help is needed, thanks!
