PC sending no signal to my monitor

I have built a PC and put it all together, it starts up. But no signal to the monitor. Please I need some help here. No pins on cpu damaged, aligned correctly, Ram installed etc etc. Please pulling my hair out here =-[

AMD Athlon X4 760k Black Edition,

MSI A78M-E35 Socket FM2+ 

Crucial 4gb Ddr3 1600 Mhz

Sapphire R7 260X OC

Seagate 1TB Barracuda 3.5" SATA-III

Corsair CXM 430W Semi Modular 80+ Bronze Power Supply

make sure the monitor is connected to the gfx card not the mobo, also that the gfx card has the powere connected to it if needed

Thank you, i got it working, i had to disconnect both the hard drive and the cd drive to give it a "Bump start"

Bump start? Not enough initial power to post?

I guess so, seems odd but it worked
