"No Keyboard Detected", but all 3 of keyboard's LED lights are open?!

Hello,

Today, while I was deleting a file on my computer using the Shift + Del command, my computer let out one long beep, and the display (and the keyboard, and the mouse) froze.

I tried to reboot, and I noticed that all 3 of the keyboard's LEDs (Num Lock, Caps Lock, Scroll Lock) are open, but my screen displayed a "No keyboard Detected, press F1 to continue" error.

This error is somewhat ironic because I can't really "press F1 to continue" since, you know, my keyboard keys aren't working, but it's making me wonder what happened because even though the keyboard keys aren't working, all the keyboards LED lights are open.

Any idea what's going on?
