GA-H87M-D3H - Turning itself off after 10sec, turning itself on again - loop

[dittz]

Hello guys!
My system was running fine since I assembled it three weeks ago, until yesterday. I left my pc turned on, and when I came back it was off. I tried to turn it back on but now I got this:
I turn the PC on, everything starts spinning, no screen, lasts for about 10-12 seconds and it goes all off. Stays off for 2 seconds and turns itself on again, only to do the same! And loops on forever util I pull off the power cord.

My system:
GA-H87M-D3H
Intel I5 4440
32gb 2x2x8 Kingston HyperX Beast 1600mhz - KHX16C9T3K2/16X
Gigabyte Windforce GEFORCE GTX 760 4GB
PSU Cooler Master 550W - RS-550-PCAR-E3 (the only thing that I kept from my old setup).


What I've already done:
I've disconnected my SSD, both HDDs and Optical Drive
Exchanged all RAM with my old Kingston DDR3 1333mhz
Replaced the GPU with my old AMD 5770
Replaced the stock cooler with a CoolerMaster Blizzard T2
Cleared my CMOS

The results are all the same, 10-12 seconds with everything spining, then off for 2 seconds, back on for another 10 seconds and keeps looping. Screen remains blank during all stages.

The strange thing is that that setup worked without any issues for 3 weeks.
Thanks!

Not that it would make any difference, but actually when I power on it lasts about 18 seconds.
Tried with my CPU out and in this case it lasted only 2 seconds. The CPU is heating, so I doubt it's defective. Centering my concerns on my PSU, the problem is that I don't have other one to test

that video card requires at least a 500 watt psu. which leave 50 watts for the rest of your setup. Now i don't know how old that PSU is but on average it loses 5 to 10% per year so if you had it a year then it is putting out between 500 to 525 watts. It would be the first thing i corrected.

If your video card calls for a 500 watt power supply i wouldn't use anything less than a 750 watt psu with a single 12 volt rail.

You have a problem with the CPU and or the CPU socket. Make sure you don't have a bent pin in the CPU socket.

You computer will run all day if there isn't any thing wrong with the CPU. What I mean is you could take out the video card and memory and it will stay running.

The first thing the MB looks at is the CPU and if that isn't working it will do the boot loop. If you are having problems with memory or video card you will get beeps.

In most cases, multiple +12V rails are actually just a single +12V source just split up into multiple +12V outputs each with a limited output capability. 

I thought the same thing till I came across the link one time.

Thanks for the answers!

I've checked the pins and they seem fine! I don't thin it has to do with physical damage, because the system kept running ok for 3 weeks, the case stayed at the same place, so I can't think of a way the parts could have suffered physical damage!

Well, just tried a new PSU, a Corsair CX600 and it didn't help. I don't have a pc speaker, so I don't have any beeps.
I am left with only the CPU and the Motherboard as the possible origins of the problem.

Any additional guesses?
Thanks in advance!

Hi, dittz!
Here my topic - http://forum.giga-byte.co.uk/index.php/topic,14785.0.html . I have same problem.
Today I went to the service center. They told me that this motherboard has a lot of problems. In this case  problem is related to the incompatibility of the CPU and motherboard revisions. Now I can exchanged motherboard with any other.
If you do not find a solution to the problem - contact the service center.
