Question Why do all my fans turn on, but I get no display?

[Gavin Schmidt]

I have recently put together a budget gaming pc. I have not been able to get any display. When I turn it on the only thing that happens is the fans turn on. The specs are the following:
-Asrock 970a-g am3+
-fx-8350 Black Edition
-PNY GTX 960 xlr8 2gb
-750watt EVGA psu
-2 x 8GB 2Rx4 PC3-12800R Samsung ddr3 RAM
I brought it to get fixed and was told the motherboard was faulty so I bought another, but it still had no display. The graphics card seems good as well. I suspect it’s bad RAM. Does anyone have any other ideas before I go buying new RAM? Also if I go buying ddr3 RAM around 2400mhz what would anyone suggest?

canned diagnostic speaker rant: speaker making 101
The diagnostic speaker is the motherboards main diagnostic feedback device.
the motherboard may be telling you where the problem is.
my speakers have this plug

I use lamp wire but any stranded wire will do. literally any stranded wires. strip one end like so

attach the stripped end into the speaker spring clips on the speaker.
the other end of the wire should be trimmed like so the semi strip

by doing a semi strip the wire case is now the socket.
plug one wire to the first pin, and the second onto the fourth pin.
power on the system and listen for beeps
