Made a scratch on the motherboard near the cpu heatsink holes. When i tried to turn the PC on, the led light in the fan flickered for a moment and the pc didn't boot up. Motherboard debug leds dont turn on eithee.
EDIT: TO CLARIFY, MY PC DOES NOT TURN ON AND ONLY THE LED IN TBE FRONT PANEL FAN TURNS ON FOR A SPLIT SECOND. THIS COULD BE DUE TO ME NOT CONNECTING THINGS PROPERLY, BUT PLEASE TAKE THIS INTO CONSIDERATION.
