So I just upgraded a bunch of parts on a Pc and when I turn it on everything works, and when the bios for the new motherboard loads the mouse and keyboard work just fine but when I boot to win 7 the mouse and keyboard don't respond to inputs. The lights for the keyboard and mouse work fine, and I know they work on another computer. What should I do? Is there a way to delete the drivers of the c: drive if it on another computer and boot from another ssd?
