My HTPC Rig:
Intel Core i7 2600K with stock cooler
ASRock H67M micro-ATX Mobo
GSkill F3-12800CL9D-4GBRL (Also tried Kingston KVR1333D3N9H/2G)
ASUS DRW-24B1ST/BLK/B/AS (SATA)
Maxtor DiamondMax 21 320GB (SATA)
Samsung Spinpoint 1TB (SATA. Haven't connected yet)
Antec Basiq 500W PSU

I put together the above rig a couple days ago. The PSU and Maxtor HDD are the only things i'm recycling from my old PC. Everything else is brand new.

The computer boots without problems, recognizes the devices connected to it. Boot from Windows 7 disk is successful. The setup screen gets to the language selection page where i can click "Next", then on the next screen, where I'm supposed to click on "Install now...", the computer shuts down as soon as I click.

The first time I booted, windows setup could not install on the already created partitions, so i reconnected this HDD to the old PC and removed all partitions. At this time, I read in the Mobo manual that HDD should be in the AHCI mode. So i changed IDE mode to AHCI mode. Then I connected back to the new PC and created 3 partitions, then when I selected the partition to install the OS and clicked next, the PC shut down. Now when I boot, I click on Install Windows button and the PC shuts down...it doesn't even take me to the partition menu. This happens each time I tried to install. Even when I tried with Ubuntu, the same thing happened.

One interesting thing i noted was when i didn't have the install DVD and the system is saying "Bootloader missing"... "press ctrl+alt+del to restart" and I unplug the USB keyboard, the PC restarts. I read somewhere that legacy USB support can cause this, so I have disabled that in the BIOS but still no resolution.

I have tried the following:
> Tried a different RAM (Kingston KVR1333D3N9H/2G)
> Removed CMOS battery to reset and tried again
> Kept a watch on the CPU temperature. Maximum it went up to was 48C. I re-applied thermal paste and re-aligned the stock heatsink/fan
> Tried install with HDD in IDE mode and AHCI mode
> Tried Windows 7, Windows Vista and Ubuntu
> First tried with 20-pin ATX connecter and then connected the additional 4-pin (for a full 24-pin connection)
> Disabled USB legacy mode
> Reconnected the HDD to old PC and was able to install windows 7 on it

All the above steps haven't resolved the issue. Any suggestions to get this resolved are appreciated. I have emailed the ASRock customer support also.

Let me make sure I'm understanding this correct...

Your power supply has a 20/24 pin connector.
You tried it first with only the 20 pin portion connected.
What did you do with the additional attached 4 pin connector?
(these are not two separate cables)
Did you have the EPS 12V 4 pin/8 pin cable connected?

The Antec PSU has 20+4 pin connectors as separate cables. A small notch makes it possible to combine them and use as a 24-pin connector. The 4-pin EPS was connected to the motherboard.
