So I think I find the solution to the problem of no shutdown with this,a new bios.
I flash it with my pen drive and upon reboot i I have in front of me the weirdest POST screen ever.
It detect cpu and next it simply says
Loading from Bank 01 ""
I have to pause screen to catch this,cause the next thing that happens is that it says
press any key to continue
I do so and system seems to reboot and screen goes black as if it werent posting.
I cleared cmos 3 times through jumper and first boot is always same with this message of loading bank
Wth,am I gonna have to RMA this mobo?
