Hey forum members

First of all, this is a cool website. It gave me a lot of ideas. Last week i started to build my own custom mini ITX config. I used a stock XBO 360 203W power brick and a 250W 12V chinese (maybe realan) 1106 psu from ebay. The problem is, my config shuts down immendiately when i press the power button on the case. The CPU fan spins one, the optical mouse flashes one and that is all. I've tried this Xbox - realan combo on my other build FM2 A4-4000 PC and it is working perfectly.
Mobo: Asrock H67M ITX HT
CPU: i3 3220
RAM 4GB DDr3 Geil
SSD: OCZ vertex.
Ansolutely no beeps or posts on the screen...
I followed the online tutorials to convert the xbox power brick to 12V.

Update: it successfully powered on once. After installed win7, i shut down the PC and doesnt power on anymore....
Bios voltages: ( i was able to check it once it powered on)
Vcore: +0,976
+3,3V 3, 424
+5V 5,040
+12V 12,091

What should i do?
Thank you very much. Sorry for my terrible english.
Have a nice day.
