This computer doesn't have an operational system yet, I built it and after I turn it on I see the motherboard screen "press del to enter setup". Five seconds later it turns off (even if I don't press del, it's a hardware problem)
I tried to remove the RAM memory sticks and turn it on but it turns off after a few seconds also.
