After booting my custom built computer, neither the VGA nor the HDMI methods from the video card seem to emit any signal to the display. I have tested both a regular VGA screen and a modern HDMI screen. Both did not receive signal. Below are the specifications from my computer build:

• Intel Core i5 3350P
• ASRock B75 Pro 3-M
• Seagate Barracuda 7200.14 ST1000 DM003 1000GB
• Corsair Vengeance LP CML 8GX 3M2 A1600 CGB Blue (2 cards)
• Cooler Master B Series B600
• Club 3D Radeon HD7870 XT Jokercard
• Samsung SH-224 BB Black
• Sharkoon T28 Case

The motherboard does not emit any beeps on startup. The CD tray opens properly and all fans spin. All cables are properly connected. All components are new and no damage was found on any of the components. The fans on the GPU spin aswell.

The VGA test we did was by using the onboard graphics from the Intel i5, but this gave no result. The HDMI test was from the GPU which did not emit any signal either. We have not been able to test out the DVI, could this be important to test, even though all the other methods did not work?

Thank you for your time and hopefully reply.
