Apparent mobo problems

Today, out of nowhere, my PC starting behaving "badly", asking to be powered off.

After that it refused to complete the boot cycle, or at least not in the time it should.

My mobo is Gigabyte GA-Z97X-Gaming one, with Intel i7-4790K, non overclocked.

Memory is G-Skill DDR3-1600, 9-9-9-26 1,50v also running standard.

To try to find out the problem I connected video to the on-board connector and unplugged all memory cards but one.

Also swapped booting SSD.

Boot takes about 4 minutes, and the Debug LED codes on board do not help too much on what might be happening.

As of now, my main suspect is the mobo, but I wonder if it is.

How should I proceed to find out what might be happening? Please suggest some directions.
 
Maybe this might be useful

Do a visual inspection of the mobo. Look for any burnt, browned, white, or discolored pieces. If everything looks normal, pull the CMOS battery to reset everything. Then I would try making sure BIOS is updated properly.

It could be a defective motherboard, or it could just need minor upkeep. Start with the small stuff first.
 
While awaiting some feedback, what I did was to pull out all the memory cards and the video card.

Next I switched to another boot SSD.

Doing that, I could get the PC to boot, only it took several minutes to do it.

It was also advised somewhere to pull any USB units I might have connected. So I pulled out my external DVD player.

That did it. Boot was almost instantaneous again, so I started putting things back. Video card first and mem cards after.

Then I connected back the original boot SSD, and there seems to be a problem with it.

After a few minutes, a screen opens that I couldn't yet read what it is, and the computer shuts down.

So for now I will stay on my other SSD.

Just one question. You were able to boot without the memory cards?
 
Just did try to boot without the memory cards. I couldn't. What does it mean?

BTW: are those boards tricky to plug completely in when you have four of them. You seem you did, and there's a bit to go yet.
 
I have just checked that you can't boot a PC without memory cards, only if the bios is modified.
 
start by changing the cmos battery. I know it sound odd but all sorts of weird thing happen when they get low. I have z97 system here that was having boot issues until I changed it.
