Help needed

My little brother just corrupted my mom's PC with Runescape.

Whenever I try and open my computer, I geta blue screen.
I can't run the computer in any mode.

Is there any way to fix this, PLEASE.

Lol Runescape.

RuneScape doesn't cause BSoD. Enjoy your viruses.
Try removing any hardware that's not needed (iPods plugged in, printers, DVD burners, whatever is plugged in to the outside of the CPU).

I know you said you can't run the computer in any mode, but that's vague as to what you mean. Did you try Safe Mode?

What os are you running?

Yeah I tried running safe mode, didn't work :/

Maybe you should tell what the error given is. MAYBE.
