I am currently building my own PC right now and I need help. I was doing an external boot just to try it out and see if it worked and it turned on and gave me the beep but nothing showed on the screen. A couple of hours later I took a break and figured out that the problem may have been I was missing the 6 pin cables to the graphics card. That was the old problem but now I can even turn it on anymore. I have only been able to turn it on once since I came back to it. Im not sure what happened.
Well I managed to solve my own problem there. After messing around with the cords a bit it finally turned on and it was the 6 pin cable I was missing as screen finally turned on.Only half way through on building it now hopefully I wont have anymore problems but if I do I will come back for help.
