New Build won't boot

I just built a PC and when I turned it on for the first time I got nothing. It powered up, all the fans were running, but nothing showed on the monitor.

Here are the components all from Newegg. I’ll be installing Windows 7 Pro once I get that far.

Here is a picture of a cable that I don’t know what it belongs to, if it’s even used at all:

Can you please give me some suggestions on where I can start to figure out the problem?

Thank you very much

  1. I would start by going through this checklist step by step:

    Also, do you have your MOBO correctly sitting on the motherboard standoffs that came with your case.
    Do you have the CPU fan plugged into the proper slot?
    Do you have the 6/8 pin PSU connectr plugged into your Motherboard?
    do you have the 24 pin PSU connector plugged into the motherboard?
    If you hav everything correct and you have case speaker connected you should hear 1 beep indicating a successful post.
  2. I'm such an idiot. I didn't have the power to the CPU plugged in.

    I still am not getting a beep when booting up though, but windows is now installing

  3. You need to have a case speaker plugged into your motherboard
