computer booting problems

Hello,

Firstly heres the machine,

Gigabyte GA-Z77-D3H Motherboard,
i5 3570k Ivy bridge CPU,
Corsair H60 Watercooling,
16GB Corsair RAM,
GeForce GTX 550 Ti
640GB HDD,
550Watt PSU,

It was bought of a friend who had it just over a year, I have had it for the last few months working fine. All of a sudden it would not turn on and kept tripping upon start up. I have stripped the machine and tested components on my old machine. The PSU is fine and working, as are the ram and gfx card. I have disconnected everything and breadboarded the build.

Instead of tripping the machine now keep restarting itself every few seconds, fans come on etc but in intervals of a few seconds.

Could it be the water cooling system that has gone as I cant hear any noise from it when it starts. If so would it make it restart so suddenly, I assume overheating would occur later into booting up.

The only thing I can think of is the motherboard?

Any advice or potential tests would be great and thanks in advance,

Steve.

I appreciate the help, here is some more info hope it helps. I have tested both my PSU's on two machines both run fine on the first, the other machine has the problem of restarting before it can post a beep.

Here is my first PSU:

Here is my second PSU:

Both are 550w PSU's.

The computer that is not booting, I have disconnected the HDD and RAM and still no post beep.

Here is the PSU on the computer running, on the computer with the issue I cannot reach the BIOS so cannot check temps. (I have tried resetting BIOS on motherboard). It was going around 66 -70.

Here is a video of the computer rebooting.

Thanks for your advice so far, I had gone through the check list and completed each task prior to posting.

Would my best option be to try replace the cpu cooling or the motherboard first?

Well, there is certainly something wrong with the CPU cooler. The CPU shouldn't be anywhere near 70C in the BIOS. The PSUs aren't quality units either, but either way there is definitely something wrong with the water cooler. Are you sure all the cooler connectors are plugged in tight and haven't come loose?

If you still have the original stock cooler that came with the CPU, you can try installing it. Just remember to go into BIOS and disable (or reset) any overclocking parameters. That would give an indication as to whether it was the cooling system.

Update so far.

Replaced cooler with Corsair H60 2013 water cooler.
Replaced the Mobo with a like for like new board.

Same issues of booting then restarting every few seconds, could it be the CPU?

Thanks,

Steve.

So far I've been trying to boot without ram in to get the beep codes. The computer makes no beeps what so ever, it just has a "vrooom" sound, shuts down then restarts and goes "vrooom" again. Exactly like in the video posted previously.
