MSI Z77A-G45 won't start

[bigpoppastuke]

Hello,

So I recently just built a computer for my girlfriends dad and the thing won't start up. The most I get out of it is the fans move an inch and then it turns off (split second being on). I thought it was a grounding issue, so I re-seated the motherboard and checked to see if any spacers were touching it where they shouldn't be (nothing wrong of course). I've removed the RAM one by one (only 2 modules) and attempted boot, still nothing. All cables are plugged in properly.

Intel Core i5 3450
Kingston KHX1600C9D3B1K2/8GX 8GB Kit 2X4GB 1600MHz DDR3
Cooler Master Extreme Power Plus 600W
On-board Video
Seagate 2tb hard drive

All of the components are brand new. I would really like some suggestions as I've never seen this before. On top of all this my girlfriend threw out the boxes all the components came in.

Alright, I managed to get the system to at least turn on for a a few seconds. However, now it turns on then 5 seconds later restarts (keeps continuing like this forever).

Any ideas? It's late and I'm stumped

Does it start the loop when windows tries to load, or does it loop before that?

(Can you go into the BIOS and look around without it looping?)

Ugh stupid phone double posted

No windows. No bios. I'm pretty sure I figured out the culprit. It's overheating fast because during installation some pins were bent. I straightened a few but still having the same issue.
