My machine has a P4i45GV MotherBoard by ASRock. I was working on my combo when I suddenly heard some sounds like a short circuit. I was very fast at switching off the power. Now it can't light up i.e. the power led is not lighting up. But when I switch on the machine both the CPU fan and the Power Supply fan rotate for One Second. The Board seems to be fine. How Can I know for sure that the motherboard is/isn't spoiled.
