Cold boot issues, need help figuring out next steps

I have been having this issue for some time, but it's getting worse.

Setup :

Intel 4770K
Asus Z87-A motherboard
2X 8Gb Kingston DDR3 PC-1600
2 X Intel SSD
EVGA 1000W G1 PSU
2X NVidia 980Ti
Some other non significative items

I built this computer myself 3+ years ago. Before this I never had an issue with it.

Symptoms: on cold boot after a few hours of being off (like 5+ hours) my computer refuses to start. The monitor comes on, but there's nothing on the screen. No BIOS logo, no error, nothing. The red "boot device" stays on on the motherboard, nothing else happens. Sometimes it will stay like this and finally boot after 15-20 seconds. Sometimes I have to shut it down by holding the power button and try again. Sometime (like this morning) it will take 2-3 tries to start. Sometimes it works the first time, like there's nothing wrong at all. It's been doing that for the last 2-3 months, randomly, but it looks like it's getting worse.

I changed:

PSU. It's brand new.
2X 980ti are "new to me" cards. The problem was already there with my previous cards (2X 970).

What could be next:
Memory?
Motherboard?
SSD?
CPU???
Other?

What do you guys think? The red "boot device" LED on my MB is puzzling me... I'm not sure why it stays on. It points to the SSD being in trouble, but I have a hard time believing that. Also..... Why would this happen only when it's been "cold" for more that 5 hours?? Some friend mentioned replacing the motherboard battery, but if it was gone or mostly gone, I would loose my BIOS settings, wouldn't I?

I need suggestions on what would be the next logical step! Thanks!

    Sounds like you may have some motherboard wire issues that get cold and shrike and then expand after the start attempt warms them. I suggest a new motherboard.

  2. Yeah, the mobo is probably next on my list... I think I'm going to order a new mobo and new mem sticks, and just try it out. Sucks though to replace a mobo for a somewhat aging CPU, but it's still good and I wasn't planning on replacing it...
  3. If you need a cheaper replacement this one is pretty good.

  4. Yeah, I have seen it for 65$ CND after a mail-in rebate. Looks "too" cheap to be good but I'll have a look at reviews... Might be good enough... Although a quick look at it doesn't give me a good vibe for a multi-GPU setup.

  6. This MSI is a bit on the pricey side over here. What do you think of the GIGABYTE Z97X-UD3H Black? I don't know Gigabyte much for they mobos (used to be an Asus fan for mobos and gpus)... but I have their 980ti and it's pretty solid.
  7. Just a follow up on this issue, if you have an Asus motherboard with POST LEDs, "listen" to them! Mine was telling me there was a problem with the boot device. It turns out it's an issue with the SSD, or the SATA cable, or the SATA port on my motherboard... For the last few days I've been switching things around to try and diagnose the problem. For the moment it looks like one of the SATA ports on my motherboard is failing. I ordered a refurbished Asus Z87-A from eBay for 60$. I didn't see the value in paying for a brand new Z97 board and with the same board I can keep my current Windows 10 installation...

    So I'm just leaving this for other with similar issues...

    Thanks elbert for the help and suggestions on replacement motherboards...
