CPU not working.

[c2tarun31]

I assembled my new PC. This is the first time I am building my PC. When I am powering it on I am not hearing any beep, however fans connected to motherboard are starting.
I am using Asus Z170 Sabertooth motherboard with Core i7 6700 processor. There are four lights on my Mobo and one states CPU, which is not powering on. Please check attached picture.

Here is the image of my motherboard https://imagebin.ca/v/2dy7QYjsN5Je
As you can see in the image that DRAM and PWR lights are glowing but CPU light is not. I tried disconnecting everything and just having CPU and RAM on mobo. Still no luck.

Any suggestions?

Have you tested each RAM slot with single module?

Do you mean only one RAM at a time and test each slot like that? I can surely try, does is going to make any difference?

Going to try now.

"does is going to make any difference?"
Yes, it does. See if the system does POST.

Yup it did. Wow... what happened here?

Here is picture of my RAM slots, https://imagebin.ca/v/2dyFfezt8o2T
I have four slots and 2 8GB RAMs. I removed one and moved other one to a different slot a time. Now when in third slot I can see CPU light is on, Boot light is on. Infact all lights on my Mobo are on. Can you please explain me, what happened and what is the problem?
Thanks.

With single RAM configuration, check each RAM slot and see if getting signal on monitor when starting the board in each case. If not, see what RAM slots not working and then we'll further troubleshoot.

With single RAM I am getting display with every RAM slot.

Interesting. What about dual channel? Test firstly A1, B1 and then A2, B2.

I tried that too now, A1 B1 are also working fine. Seems like it all starting working on its own.
Don't know what happened.

Probably a RAM module not fully inserted.
However, good luck with the new setup!.
