Hello, I have strange problem on a build that I've done. When shutting down Windows 7 PC turns off alright, no problems on starting ether. However, when I select to restart, I get a "no signal" monitor message and no view. No bios messages, absolutely nothing after restart. Running out of options here, need some help.

Specs are:
600W chieftec PSU
MSI gtx 550Ti
amd phenom II cpu
4GB kingston DDR3 1600 (single slot)
sata2 HDD
ASRock N68C-GS FX mobo

Things I've done already:
Replaced the mobo to the same model.
Tried internal VGA.
Tried different monitors.
Updated bios.
CPU, ram and PSU are brand new, there is a a very small chance of something wrong with them.
