Fresh build, on turning power on, mobo lights are on, but no beeps or display

[abhishekmaity]

After the build is complete, when I turn it on, the mobo lights up and the fans start spinning. However, I don't get any beeps and the monitor says no display port (the monitor came only with mini displayport to displayport cable, so I'm trying to hook up the displayport end with the mobo displayport and the mini displayport to the monitor).
Went through these suggestions: http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems. The only thing I didn't try is #11, as I'm feeling skeptical to take off the CPU fan (putting in on was the hardest part of the build).
There was no beep speaker with the cabby or mobo, and I'm not sure if there's any inbuilt speaker in mobo. There are some LEDs in the ASUS mobo for RAM, CPU and Display. They turn on momentarily one after another and thrn turn off. I'm not sure what that indicates. When I tried to boot without RAM installed, the RAM led stayed on and other two didn't light up at all.
Also, The ASUS motherboard supports DDR4 and also supports 2666 memory. However, the specific corsair RAM I'm using (DDR4-2666 2X8GB) is not listed in mobo's qualified vendor list. Can this be an issue? I don't have a spare RAM so want to be sure before I get another.

Please post your full specs.

There are numerous causes ranging from incorrectly seated cables to a dead component - but without seeing your build, it's difficult to start anywhere.

If you're not getting any beeps at all, you don't have a motherboard speaker - they are becoming rare. You'd get a beep whether all was good or something was bad.

As far as the CPU fan, just ensure you've attached the CPU fan to the fan header (usually marked CPU_Fan or similar). Is that particular fan spinning? Without it, most rigs won't boot to avoid damage to the CPU.

The CPU fan is spinning when I turn on the power, as well as the case fans.
Last time I made a build was with the good old speaker. I'm clueless how to debug POST issues without it.

Very much trial & error I'm afraid.

On the plus side, as I'm sure you know you've gone with quality components throughout - so we can make some reasonable assumptions. (That's not to say you can't/won't have a defective component, but the odds are better).

Looking at the manual for your board, the 2xDIMMs, have you installed in slots A2 + B2 on your motherboard? Page 18, middle diagram: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/Z170-PRO-GAMING/E10719_Z170_PRO_GAMING_UM_V2_WEB.pdf

Yes I have connected to those 2 slots.

What bugs me is that the RAM part is not listed in the motherboards qualified list. However, judging from the LEDs there shouldn't be an issue. Here is the reference to the LED meanings (Page 40): http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/Z170-PRO/E10417_Z170-PRO_UM_WEB.pdf

The QVL's are one of the last things to ever be updated, in fairness.

You may require a BIOS update to support you RAM, which is another problem.

You've tried to POST with only 1 module, in slot A2? You've reseated all power connectors? There's nothing shorting the mobo in your case? (a dropped screw perhaps)

Did you breadboard the rig to begin with? Build outside the case, only mobo/CPU/HSF, 1xRAM + PSU connectors? Did you get a post at that point?

If you did, you're going to have to start removing components. Especially the GPU and see if you can post with onboard.

If you didn't, I suggest you start over. And breadboard to begin with.

Breadboarding is one of the most important elements, for this very reason.

If a rig doesn't post/display with only the basics, you have a larger-scale problem to deal with (hopefully just a BIOS update thouhg).

Thanks for all the help. I feel so dumb right now.
The monitor cannot auto detect which port is plugged in. By default it looks for displayport (not mini displayport where I was plugging in). I needed to manually go to monitor settings and change to mini displayport. My buid was working properly all along.
