AsRock H81 PRO BTC R2.0 Does not start BIOS, no PO

Hi everyone!
I?™m building my first mining rig and there are one issue i face it right now that I can't figure out the solution myself.
Here are the specs:
MB asrock h81 pro btc r2.0
SDD
Intel Celeron G1840 Dual Core 2.8GHZ
8 gb ddr3 ram
MSI AMD Radeon RX 580 ARMOR 4gb
1300w PSU

I have one more GPU the same RX 580 and one more to come. Stil haven't receive my PCI-E risers, so I want to set up bios, install windows and everything. For that one GPU is enaugh, right?

So I installed everything on my motherboard and it worked very well. I mean fans on CPU, PSU and GPU are rotating and?? ??that's it. Nothing happens. Fans rotate for some time, then slow down and then rotate again as normal. I connected monitor using hdmi straight to GPU - nothing showing. I plugged other monitor using D-Sub connector on MB and nothing. I also noticed that my keyboard (Works perfectly on my other PC) I plugged in MB doesn't work (for example num lock button desn't light on/off when pressed). Looks like all usb slots on MB are without power. Also this D-sub slot for monitor doesn't give any signal or sign that it's doing something. Monitor is just blank. I expected to see bios startup, so I could install windows, but nothing.
Do You have any idea where is the problem?
Do You need any additional data to understand where the problem is?

Thanks in advance.

Your picture shows nothing connected to the GPU, just the Intel iGPU.

Remove the video card, and use the jumper on the board to clear the BIOS/CMOS. Connect the monitor to the iGPU and see if you get any video to the monitor. Be sure the monitor is set to the correct input, or set to Auto Select for the input.

This is to test if the PC is starting with your first try at using the board. Are you sure that the cable connected to the eight pin CPU power connector is a CPU power cable, and not an eight pin video cable?

No idea what model of memory you are using, and if it is compatible.

Connect the keyboard and mouse to a USB 2.0 port.

If you get a signal to the monitor with the iGPU, then you can try the video card.

Have cleared BIOS/CMOS - after doing that i get short (electricity) in room. I switch it back and my computer starts as usual (without POST). Tried to remove and plug in other slot RAM - that doesn't change anything. Ran without RAM - nothing. And all these four USB ports - they doesn't work. I mean none of them. Keyboard is not active. No lights on it, nothing. I'll purchase this small buzzer/speaker for MB and try to figure out what sound does it make when i try to boot. And follow these instructions: https://www.biosflash.com/e/bios-beeps.htm Any other ideas?

A POST beep speaker won't help, the BIOS option to enable the beep speaker is set to disabled by default.

I'm not sure what you mean by, "Have cleared BIOS/CMOS - after doing that i get short (electricity) in room. I switch it back and my computer starts as usual". The board won't start with the clear CMOS jumper in the clear position, that is normal, it must be on the non-clear pins. You only leave the jumper in the clear position (with no power at all going to the board) for a few seconds, and then move it back.

You didn't say if you tried to start the board without the video card, just using the iGPU.

You never told us what models of memory you are using. The board won't do anything without memory installed.

Have you used that PSU in another PC?

Nevermind, after resetting the cmos it is now working.

It worked for me after setting the PCIe gen to 2. You might have to do some configuration to your BIOS (UEFI)
