Originally I posted this in the Motherboard/Gigabyte forum. Because I thought it was probably a motherboard fault.
But I decided to test the power supply first. I used to know my way around electronic thingies, but that was twenty plus years ago. I looked up on the internet, how to test a power supply and followed the steps.
I removed the power supply connectors to the motherboard. I shorted out the green and black wire on the 24 pin connector, to start the power supply. I then tried to test a black/yellow combination for twelve volts, as pictured in two different sets of instructions, I’ve looked at. I‘ve got a multimeter set on a 20 VDC scale. The power supply immediately shuts off, like a circuit breaker blowing. I turn the power supply switch off then on, and the connected fans start to spin again.
Now, am I just shorting this sucker out, which certainly seems to be the case to me? As I said, I’m following instructions found on the internet. Or is this an indication that the power supply is bad?
The original problem, that I’m trying to solve.
My computer will not freaking work. I press the power on button. It does not make any calls to or attempt to access: hard drive, optical or floppy disk drive. Nothing appears on the monitor. Fans start to spin. Ten seconds later the computer turns itself off. About 1 minute later it tries to restart itself. This cycle repeats, until I turn the power supply off.
I built this system in November of 2007.
GA-P35-DS3L
Intel E6750
Crucial Ballistix DDR2 800 PC26400
Samsung Hard Drive and Optical
Sony Floppy
Antec Earthwatts 430 watt power supply
What I’ve done:
I’ve verified power going into the power supply. I’ve reseated all connectors, cards and memory except the CPU. I’ve tried bootable disks in the optical and floppy drives. I’ve tried clearing the CMOS. I’ve tried running the computer without drives, without memory and without the video card in all different ways. The same things happens. I’ve pulled the motherboard reset the wire, I thought it might have been stuck closed. I put up my shotgun against the computer and tried threatening it.
I am down to three options.
Bad power supply
Bad Motherboard
Bad CPU
I plan on trying the power supply first. Does anyone have and advice or suggestions?
Thanks

What I've done, since. I've connected a pc speaker to the MB, all it does is give me one beep when I first press the power on button. It is silent there after. I've also removed and checked the motherboard for shorts, nothing.
