Hi,
I'm currently helping a friend build a core i5 750 system with an asus p7p55d-3 pro motherboard.
Last night, when attempting to boot for the first time, there was nothing. The MOBO power LED came on but there was no apparent attempt to turn on. I screwed around a while, and figured out that I forgot the CPU power, plugged in, still nothing. I tried adding second 2x2 cpu power, and nothing.
The only way that I've been able to get the board to attempt to boot is when I removed the 2x2 connector adjacent to the 10x2(?not sure on exact size) motherboard connector.
When I did this without the cpu power connected, the cpu light came on, no vga but it does at least power up. When the cpu power is connected it boots for 1 second, shuts off, repeats, over and over until I shut off power supply. Plugging back in the 2x2 cable = no more booting.
I'm really not sure what this all means, but my best guesses are that the motherboard is grounded somewhere and shorting out, or that the power supply is bad. I am taking my rig over tonight to test some of the components and I was wondering if anyone had any other ideas on what the problem could be here.
