So I got an ASRock h81m-hds and everything on it looks okay (No bent pins, etc..) but when I try to boot, it shows the windows logo for about 30 secs and the whole pc shuts down after. When I try to go to BIOS, it works but will inevitably freeze and become non-responsive after about 30 secs as well. I've tried resetting the CMOS. The thing is everything works fine when I used the same hardware on my Asus h81m-a. Is there a solution for this or is the motherboard really broken?
