PC not showing input signal?

[Cerealmemer]

So I just installed an EVGA 500W into an older PC I had laying around. When I start it up, it beeps once, then beeps again, but there's no input signal. I've already tried resetting the BIOS, but still the same problem. Is my PC broken, or did I install it wrong? Here's a picture of inside my PC, sorry if it's hard to see

Appears to be set-up correctly. Did you move anything on the motherboard? Perhaps bumped something and didn't know it?
Check to make sure every thing is properly and securely seated in there mounts. Check the owners manual and make sure the RAM sticks are in the correct DIMM slots.
Try booting with just one stick of RAM.

Sorry, forgot about this post. I plugged a VGA cable into my motherboard instead and it worked.
