I just finished my first build. Everything is working... except we have no display on our monitor. Lights are on, fans are running. I even switched it out with another computer's graphics card and it still has no display. Here is what we have:
I'm not family with "Diablotek PHD550 550w ATX Black PSU " ....
Power Supply Not stabe will also cause that ..... but do you have another one to test.... for this system you better buy some know brand PS... such as CoolerMaster / Corsair.... for $38 I don't think this is what we can trust..
and make sure "24 Pin Power and 8Pin Both Connect to Motherboard "
