No Signal *sigh*

[Domokun_index]

So I just built a PC for my brother. It's not my first so I don't believe anything is wrong with the setup.

Post boot, I get nothing on my monitor (no signal) yet my parts are working nicely, vibrating and all that good jazz.
Specs;

EVGA 500 B (Bronze Edition) - 500W.
AMD A10-6800K
FM2A75 Pro4 MOBO
Some Samsung £10 Optical Drive
Hard Drive 1TB Western Digital

There is no beep on startup.

I need all the suggestions I can get. I've tried most things on front pages of Google searches.
All feedback would be greatly appreciated! ^>^
