My pc crashed (no BSOD just a black screen, nothing on it) im pretty confident it was because of overheating, when i try to turn it on, a light on the motherboard blinks for a split second and then goes off, if i hold the button to turn it on, the light will turn on and off repeatedly, but if i hold it too long, the light simply stops until i disconnect the wire on the back. What can be causing this problem? I think it can be the power supply, but i have no idea.
