Windows 7 startup repair loop

[Moose0125]

Hello,

I have recently replaced a number of parts in my computer due to 2 hard drive failures. After finally putting everything together I installed windows 7 Ultimate. For the first few times it turned on but now it just goes straight to startup repair and says that nothing is wrong. I had this problem before so I reinstalled windows. I thought the problem was over because last time it only took one restart for everything to stop working.

I replaced the hard drive, motherboard, ram, and psu. The only things which remain are the gpu and the cpu.

Any help is appreciated. If a list of parts would be helpful I will post them.

Thanks
