    What is the brand and model of your motherboard and what are the rest of your components?

    Have you plugged in the 8 pin connector at the top left of the motherboard? Is there a speaker in your case, is it connected, and is the PC making any sounds?

    If you plugged everything in and it still doesn't work, I would recommend checking with a different PSU. Good luck.

    Edit: Also, try unplugging all unnecessary peripherals (DVD Drives, Hard Drives, etc.) and see what happens.

    To eliminate the possibility of a short against the case, try removing the motherboard from the case and place it on a soft, non-conducting anti-static surface. Install only one RAM module, the graphics card and, of course, the CPU, heatsink/fan. Actually, when you remove the motherboard, don't remove the CPU and heatsink/fan, leave it on. Connect the appropriate power and data cables, including the front panel switches and the monitor. Turn it on to see if will post. The PC doesn't need the hard drive or optical drives to do this.

    Wouldn't you know it? I thought about mentioning standoffs but I thought, "Nah." But all's well that ends well.

    To enter the BIOS hit the Delete key right after your system posts (when you hear the beep). If unsure, you can hit the key more than once. Once in the BIOS you can go to Boot Configuration Features. Remember that only your keyboard works in the BIOS, not the mouse. Next go Boot Device Priority and set the first boot device to the optical drive (DVD, CD or Blu-ray). If you have more than one optical drive, go into CD/DVD Drives to select the one you want to be first. While you are in the BIOS you can insert your Windows DVD/CD in the drive tray so that you can begin Windows Setup as soon as you leave the BIOS. Back out of the menu by hitting the Esc key until you are back to the main menu. Maneuver to Save & Exit Setup.

    While you are in the BIOS, you might want to check some other settings like setting your SATA controller to IDE or AHCI (SATA) mode, depending on what you want. In the manual EVGA recommends AHCI mode for your SATA devices.

    After you have installed Windows, you can go back into the BIOS and change the boot order to the hard drive first if you wish.

    Some BIOS' allow you to enter the boot menu by pressing the F12 key (instead of the Delete key) or some other key to temporarily change the boot order so you don't have to go back into it later and change it back but I didn't notice if your motherboard had that feature.
