blank screen first time starting computer (no beeps,no bios)

I recently decided to order parts and build my first computer (here are the parts):

(I bought two of the memory packages for a total of 4GB, I also thought that the parts were compatable)

I assembled the parts and I thought the only error I might have made was in connecting the power supply to the components. However, when I pressed the power button all the lights and fans went on and I know the disk drive was working. Using a HDMI connection (and I tried VGA), the monitor remained blank. No bios came up and there was no beeping or shutting off or over heating.

Does anyone have any advice? I would really appreciate it.
