ab9-pro error code 9.0 and 0.0

I just turned off my pc, without doing nothing abnormal, and my pc doesnt starts any more. Ive cleaned all the board, and i could do 1 sucessfull boot after it, but locked the system 5 minutes later...whats happening? ive already cleared the bios, with and without cables, with power on and off on the power supply...nothing works! the board isnt physically damaged at all...
when i wait a little with all off, the board turns on and stops on 9.0, and than turns off after a while, and goes to 0.0 What is happening? Can i fix it? RMA?

already tryed on another PSU, but unsucessfully. did it with only the board, than with the processor...nothing. please, help me!!! thaks

does sound like potentially a PSU problem but without knowing more system details ...

Thanks for the try, the MB just came back from death. I let it resting for 2 day without battery and ccmos and it came back mysteriously....As i said, tryed it on another PSU, and iwasn[t it. Well, this wasn`t the best designed MB from abit, infortunatly....
