I built a computer 3 months ago and I am running windows 7. this morning my computer worked just fine, now I can't do anything. when I turn on my computer I get a black screen that describes my computer system and its components but it says o usb ports detected. it says to press f1--f2--or f11 to continue but the key board is not being detected so I can't press anything. does anyone have any suggestions?

Have you tried removing all USB peripherals (keyboard, mouse) and trying to start the PC?

I would check BIOS setting first.
