Computer posts but won't boot.

[cyberspacegenie]

I've just built a new computer out of some used parts:

Asus p8h77-m mobo
Intel 3570k i5 cpu
Corsair xms3 ram - 2x4gb
Samsung evo 750 sad hard drive
Pioneer blu-ray/DVD drive

After building I can get into the bios fine. SSD and bluray drive both recognised. Computer will boot from DVD and complete installation process for windows, but the computer goes into a weird loop. It starts, post screen comes up, then black for a few seconds, then post screen comes up again. It just continually loops like this. I've tried changing most of the bios settings but nothing helps, it just won't do anything with hard drives. I've changed cables, ports, reset jumpers, etc, but all to no avail. Really need some help about my next step.

Hard drives show OK in Bios.

Ram came from another computer so I know it works. SSD is new, but have also tried some regular hard drives with same effect so not the drives.

CPU and mobo from Craigslist, but the fact it reads and uses the DVD drive makes me feel that it's a setting or something I did wrong during the build.

Any help is greatly appreciated

In bios did you set the SSD To AHCI instead of SATA? Of course that is if the SSD is booting windows (lol). If you have changed settings in the BIOS, as extra measures pull the BIOS battery reboot the PC then go into bios and change the SSD to AHCI no matter what AND make sure the bios is reading the correct boot order for which drive has windows installed on it.

Yeah, tried that but didn't work. I'm trying again taking out the battery and resetting the jumpers and leaving it overnight. Will set it again at ahci when I restart it. Not optimist it will make a difference though.

I've never come across this before, I'm wondering if the motherboard is damaged somewhere, but then it doesn't explain why the it can boot from DVD and not hard drive - if it were the motherboard I would think it would do neither or both.

Bios is up-to-date, but I may reinstall it again in case it's corrupted somehow
