I've just put together my PC.
System Info:
Speccy:http://speccy.piriform.com/results/L6p5HeQqaXlW3RViB0iojDF

So far I've managed to boot it up, play games and have it run a whole session without crashing but its only when I shut it down completely, it 'powers on' momentarily and then restarts itself.

Sometimes the system remains powered on but the display fails to show.
After more than a few hard shut downs and hitting the I/O behind the powersupply, I'm able to get a message "Power supply surges detected during the previous power on. Asus anti-surge was triggered to protect system from unstable power supply, press F1"

I've just updated my BIOS yesterday and took me forever to get it to boot up again.
I'm now starting to find it real hard to get it to boot normally without doing short repetitive restarts right after pressing the power button.

So far i've done the following..
- Re-seated the ram chips.
- Re-seated the cables going into the PSU
- Unplugged the GPU/peripherals
- Connected the PC straight to the mains
- Updated BIOS
- Default settings on BIOS.
- Ran Memtest86 (Pass)
- Disabled the power surge detection in bios

Still getting bad boots.

When I'm eventually able to boot, everything seems to runs fine.
(Currently writing this message on the computer)

Not sure how to go about this..

Forgot to mention, Seasonic G series 550w.
That could be it. I have the SSD, HDD and CD drive connected to one connector.
I forgot to try using another extra cable.
Thanks

Edit:

Tried using different cables, bent back some of the IO shields pins as I had some doubts that they weren't making contact and possibly caused grounding issues.
Still happening

Good news at last.
I think I may found the issue.
I removed the parts one by one and noticed the system didn't boot properly with the graphics card on.
I moved on and inserted a DVI and ran direct onboard graphics and everything worked fine.
I checked to see if the DVI worked on my graphics card and noticed it still booted fine.
So my conclusion was the brand new Display Port cable that I purchased a day I installed my computer.
I had another DP cable lying around thankfully and switched it over and so far no problems.
Knock on wood.
Will post back if anything happens.

Thanks for all the help everybody.
