I have recently tried to upgrade my computer. When I turn the computer on I have no visual input I have tried different monitors as well as the motherboard HDMI slot and the graphics card one I have tested all the components and I have no idea what to do now.

My new setup

Amd athlon X4 760k black edition 3.8 quad core
Komputerbay 16GB (2x 8GB) DDR3 PC3-12800 1600Mhz
Sapphire AMD Radeon HD 7870 Dual-X 2GB GDDR5 Graphics Card.
Asrock FM2A75M-HD+ Motherboard

I have checked compatability taken each piece out to test them. The motherboard I had to replace but I still get no input signal. I changed the Psu and case to check it was working. I don't know what it could be. I have spent about 12 hours of my time problem solving and gotten my friend who builds his own computers as well to look at it. Please please help! I've spent about 400 quid on this.

All the parts are brand new excluding the case, disk drive and Psu which I have tested them all.

Thankyou

Andy
