Just built my computer yesterday, and it worked for multiple hours afterward, but will not boot now. I've unplugged all unnecessary parts and have found the problem to reside in either the motherboard or power supply. The motherboard shows that it is connected to the psu, however it will not boot and the fans will not start. I have tried using one RAM stick, and have isolated the problem to not include them. I've checked all the plugs and everything is connected correctly. Where could the problem most likely reside?
