Recently my computer just shut off. It wouldn't turn back on so I figured I had a video card error. It powered up but the screen didn't come on. Then I realized that my keyboard wasn't responding either. I did the best thing I knew to do and tore my computer down. The entire thing. I know at least that much of the ins and outs. I cleaned the whole pc of dust and such and reassembled. The computer works again! But. I get an error message after startup screen stating "The System Has Failed" "Service the PC to prevent damage" "Press F2 to continue"....something along those lines. What can I do to fix this?

Hi

Take all hardware off (external like printers, mouse, USB devices, etc) except for the keyboard, then try to start the computer.

What is the result?
