I just came back home one day and turned on my computer. The computer was stuck on the bios screen. The keys on my keyboard were not working (F8,F11). I tried using another keyboard but it still was not working. I opened up my computer, cleaned everything and checked my cpu, ram, graphics card, and my hard drive. Nothing seemed to work.
I have windows 7 and the last time my PC was working was when there was a windows update. Please help!
