Hello, I just built my own computer and have connected all power cords. Everything turns on just fine, and fans spinning. My VGA connected to the DVI-I on my graphics card is plugged in but the monitor will not pick up a signal therefore no display. Here are the specs
I have removed ram, tried different slots.
I have tried different DVI adapters, VGA cords and I have also tried different slots for Graphics card.
Speaker installed but no beep.
All fans run, power phase 1 light comes on.
Running my monitor VGA to a DVI-I adapter that the graphics card came with.
Made sure all power cords are in and processor in place securely.

Asus Radeon HD7770 2GB DDR5 PCIe

AMD Phenom II x4 965 AM3 Black edition

Kingston XMP 2x4(8GB) RAM DDR3
1600MHz

MSI 970A-G46 9 Series motherboard

Seagate 500GB Serial ATA HD

500W PSU Raidmax

Assuming you have followed all the basic rules of ESD precautions, have you connected the CPU fan to the motherboard? Do you have the luxury of trying a higher wattage PSU? Perhaps something along the lines of 750W?
