Wow, still no anwsers yet huh. hmmm.
I've restarted many time and it seems like it will only post when it wants to. Through trial and error, I got to post, install Win7, update all current driver and the SAME issue occurs.
I even went and bought another PSU and tested it with same existing issues.
This really blows, this is also my first Asrock board. Based on the experience I have in building PC, this one is a PAIN in the u know what. SIGH!
I'm going to give it a few attempt then I'm going to RMA this board. Kinda wish i paid a little extra for better board. Maybe i just got unlucky.
