Computer won't turn on after BIOS update and CMOS reset

Salutations everyone. i've been having this ongoing problem for a few weeks now and i'm starting to reach my breaking point for this mobo. through few trials it simply just won't turn on when it has few minutes prior to removing battery. to start off this is my current setup so far.

note: the time span from booting and posting on success, to not turning on at all is on the same day roughly 30 mins difference. I also went through this wonderfully written list to see if problem would be gone..still nothing >>> http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems <<< this is the list im referring to also i've had everything (except the CPU, being about 7 days, and the graphic card being about 3 months)... for about a year now so i have a tad bit experience of putting components in right places(not much to brag about i'm aware :) )

Case: Rosewill ATX Mid-tower Galaxy-01
Mobo: Asus H110M-k
CPU: Intel Core i7-7700k
Graphics Card: Asus GTX 1060
PSU: EVGA 500 B1 80+ Bronze
RAM: Hyperx Fury Black 16GB (2x8gb) 2133MHz

This is a story but i'll do my best to keep it as detailed as possible without boring you all down. the reason i did a CMOS reset (both 2 pin and the battery) was because after a successful bios update in order for me to use my i7 cpu(previously had an i5-6600k), for some reason it wouldn't register my second stick of ram. the bios would register the new CPU but shows only one ram running. i decided to play around to isolate the problem and it concluded that for whatever reason before bios update, now, one of the DIMM slots weren't reading my stick( the one furthest away from CPU) i even tested both sticks just in case of a faulty ram and they both worked in the working DIMM slot. i was so confused (still confused even today) as to why before the update it was fine, but now it starts acting up?

so now I've decided to try and clear the cmos both by using jumper pins, and also removing the battery. I've been told to leave it off it's holder for about 20-30 mins or so then put it back in and try again. I've also been told that press and holding the power button would also help. after said steps were taken, i tried turning back the power again and BEHOLD...no power. checked to see if power switch was set to "ON" and then confirmed it was indeed on. i then went to double check for the 24pin and 8pin(in my case 4pin for this mobo) were snugged in tight as they should be. both were seated, and i decided to remove all cables except for my Power SW, the 24, and 8/4pin.

i tried again and still had no response from the system. sadly, at this point i'm starting to take a panic sort of thinking. before that, i switch to the i5 processor just in case of a short to the i7 cpu but thankfully(and sadly..) still no response. at this point i switch back to the i7, remove cmos battery again and now i only have just the power switch, 24pin, 8pin, and 1 stick of ram connected to the mobo. this time i leave it for 5-8 mins estimate and i'm left with STILL a non-powered PC, and
no ideas that have run out in order to get me through this REALLY weird dilemma. I would appreciate any kind of help and assistance and will try to fully co-operate to the best of my abilities and will provide any more info as much as i can. thank you everyone

Last chance try: remove motherboard from case, uninstall everything. Leave only 24-pin cable connected and try starting. If still zero response, there's nothing more you can do with this setup.
However, that does not mean that motherboard is dead. There's also chance, that it is PSU that decided to suddenly die. So do the paperclip test on PSU, and test mobo with different PSU if you can.

i did. i made sure both the cpu pin and the 24pin were secured

i'm not sure i follow about this "strap" do you mean the latch that holds the battery in? or am i thinking wrong

just did a double check on the pins. far as the naked eye can see they look the same as usual. made sure to carefully place the cpus in the socket

Sorry, I'm not native. Jumper was the correct term. I should have corrected it... but I didn't since it had already been suggested.

ahh if that's the case there is no jumper on the pins. i usually remove them once i have them on for 5 seconds or so then place it back in a plastic bag where they came from. unless i'm supposed to have a jumper on ONE of the CLR pins then i'll try that
 


This motherboard has only 2-pin CLR Cmos, so it's not that.

welp..i honestly have nothing then. triple checked to make sure all standoffs were fitted, no wires or random screws going below. all of that and just wont start up..most likely i'm now thinking of it may be just a dead mobo sadly
