My computer does not boot. This started this morning, when I realized that the power went out last night. That could be the cause of my problems.
Motherboard: ASUS P7P55D LE
Power Supply: 500W
When I press the power button, it turns on, makes the normal noise that it does when it turns on (brrrnnn...), and turns off within 3 seconds. Then, the computer (without any action my part) attempts to turn on again and the cycle repeats.
Here's the thing, if I unplug a 8 pin connector between the PSU and the mobo (it's labelled "EATX12V"), it seems to boot up fine, but nothing shows up on the screen. (So I'm assuming that it's necessary to make my computer work.)
I've tried plugging my computer into multiple power sources. That is not the problem. CMOS reset seems to fail.
Anyone got any suggestions on what to do? Should I get a new power supply? Or is it the problem with my mobo?
