I Recently went to a friends house and left my computer on, I came back and turned on my monitor it was "locked". I l hadn't locked it, also the keyboard wasnt work same with the mouse. So i powered off the computer and powered it back on , and it just stuck on the Asrock logo. Keyboard wont work or anything. I took the little battery out and put it back in still nothing. If I try to power it off with the front power bottom it will turn back on a few seconds later. Do i have to get a new windows ? If i do how would I install it if I can't even use the keyboard ?
