Installer woun't start

[HijackHacker]

Hi everyone!
I downloaded iAtkos v7 to try it out on my brand new PC.
Upon loading the CD and restarting, I get to the "Press any key". I press any key, it start to load the installer, and when the white screen is supposed to come up, my pc restarts.
I tried iAtkos v5, v6, iPC, iDeneb with no luck.
What seems to be the problem?

My specs are:
CPU: C2D E8400 3.0GHz, 1333FSB, 6MB Chache
VGA: Sapphire ATI Radeon 4870 1GB GDDR5
MB: MSI Neo-F P43
HDD: Hitachi 250GB, 8MB
RAM: 2x2GB Transcend @800MHz
PSU: Chieftec 370W Real Power PSU

I fear the motherboard is not supported...
