New build computer keeps restarting during startup

Hello everyone.

I've just build a new computer which is build correctly (The cable's is placed in the right hardware an such). When i start the computer everything looks fine, but when it has been turned on in a few seconds, it restarts (However, when i'm trying to install Windows 7, it stays on in a few minuts and freezes - and of course it restarts.

It's a gaming computer with the following hardware:

seagate barracuda harddisc - 3.5′′ sata-600 1tb (Not sure if this is the danish word of that harddisc)

Kingston HyperX blu - 8GB DDR3 1600MHz PC3-12800 CL10

Intel Core i5 3350P / 3.1 GHz Processor - LGA1155

Samsung SH-224BB - SATA Intern DVD±RW (±R DL) / DVD-RAM Sort

PNY XLR8 GeForce GTX 660 grafic card - 2GB

ASRock P75 Pro3 - ATX LGA1155

Cooler Master Thunder 600W - 120 mm

I really hope that you guys can help me with this issue.

Thank you in advance
