I need some help! I can't get my mouse or my keyboard to work (in any way, including function keys during bootup) I have tried other keyboards and a mouse and the problem is clearly with the computer. I'm guessing one of my four kids erased the driver software, but I don't know how to do a system recovery or download new drivers, or anything else when I have no keyboard and no mouse function to allow me to control the computer. I need this computer to do a grad school assignment and am desperate for some help. THanks!
