PC goes on... off... on...
Hello everyone,
I built this computer myself and it's been working fine for about a year. Two days ago the PC wouldn't boot when I turned it on. Instead, it powered on for a few seconds, and then powered off, then on again and off and so on.
Troubleshooting So Far:
Power supply - I tested all of the voltages that come off the power supply with a multimeter (as per this guide here: PSU Test - How to Manually Test a Power Supply With a Multimeter - Test PSU)
Everything was within tolerances.
If I plug in the 24-pin connector (and only the 24-pin connector) to the PC, it powers on and stays on. I presume this means that the power button on the front of my PC is ok too.
I next plugged in the 4-pin motherboard power cable and the auto-power cycling problem resumes. Just to make sure the power button wasn't the problem, I disconnected both the power and reset buttons from the motherboard and powered on by shorting the connector pins. Same problem.
Any ideas?
Thanks in advance - great forum.

Welcome to TechIMO!
I would check the memory.
Just to start/
Memtest86 - Download Page
Edit:
Probably not memory,
I would set it up with minimum setup and a different power supply, if it still does it, I would suspect the motherboard.Last edited by stroyal; November 3rd, 2009 at 10:05 PM.

stroyal,
Thank you for your suggestions. I pulled the memory off the board and still experienced the same problem with the powering on and off. So I agree it's probably not the memory.
Your suggestion to use a different power supply is a great idea. I'll give that a shot today and we'll see if it works. I think I might have one somewhere in the basement :-)

Clearly Obozo has no respect for the military. They are not there to hold his fucking umbrella.
