Install windows 7, reboots continuously when restarting

[deedler]

Hi everyone.

I am running the following build:
AsRock Extreme3 Z77 LGA 1155 motherboard
8gb ram
520w seasonic psu
500gb Western Digital Black HDD
i3-2120 sandy bridge

I try installing windows 7. It restarts then completes installation completely. It restarts one last time then hangs at the splash screen for the bios for about 3 seconds, reboots automatically, then reboots again in a loop. I have disassembled the entire computer, went over every basic step I could think of and it still doesnt work. I've RMA'd the HDD, so it rules out that. Any ideas to what this problem could be?

Thanks,
Chris

Hi, What is the setting SATA in BIOS, AHCI or IDE?
Are you installing from USB or DVD?

Thanks for your reply. I believe the setting is ACHI. I am installing from DVD.

I also tried installing with a known working psu, yet it still does not work.

Try setting SATA to IDE and install again. See if still the same.
What SATA ports are the HDD and the DVD drive connected?

Turns out it was a bad OS. Burned another copy of Windows 7, works flawlessly. Thanks anyway alexoiu.
