I'll try to keep things succinct, kinda stressing and any help is appreciated.

I'm attempting to upgrade my PC, my current build is roughly as follows

Asus MOBO (Unimportant) > Upgrading to a Gigabyte Z170XP
i5 3570k > Upgrading to i7 7700k
8GB DDR3 GSkill RAM > Upgrading to 16GB DDR4 Corsair 3000Mhz RAM
GTX 980 Ti
Corsair 850w PSU

For starters, I've had this build for a good four years now, haven't really mixed things up aside from swapping for a newer GPU. I initially purchased the new CPU and MOBO a while ago, along side some Kingston RAM but I encountered an issue which left my PC powering on, running for a short time to no effect, then powering down and restarting. First thing I did was check hardware compatibility and sure enough, I noticed that the specific product code for my RAM was absent from the RAM compatibility chart on the Z170XP motherboard, so I figured that was my issue. I waited a few months due to circumstance and then replaced that with some (more costly) 3000Mhz Corsair RAM, which was listed as compatible.

Unfortunately, I just attempted to install it last night, same issue. The PC will power on, my GPU lights up, MOBO LEDs light up, fans whir, HDD spins up, DVD drive spins up, but to no effect. Shortly after it will shut down and try again. The monitor never so much as flickers. I've tested running each RAM module individually, running without the GPU, rewiring the F Panel different ways, no dice. I just put my old build back together, no problems with any of the current gear, the issue has persisted between two sets of DDR4 RAM and the MOBO seems to light up and allow power flow no problem, so I'm feeling like the CPU is the culprit.

Any expert opinions? I think due to the circumstance of having ordered it so long ago, alongside me foolishly ditching the packaging, a return with Amazon is unlikely, so I'm hoping for a solution or at least some assurance that I'm replacing the correct component.

That is not easy trick, unfortunately. You would need to insert there CPU that is already supported (any 6th gen), that would make machine run and let you update BIOS. If you have no access to such CPU, your only choice is to get a board to a comp shop and they should be able to update it for you, but you will have to pay for it - and some shops actually ask so much that you could buy a new cheap CPU for that.

Man, no joke you have just given me so much hope. I just checked my purchase history, turns out I purchased the Z170XP months before the F20 update was even released, so there's no way it could have come with 7th gen support.

Now

How in the world does a guy update his BIOS when he can't even access it?

Oh dear, oh dear. Well, I'll look around and see if I can find someone fair, hopefully they understand. Worst case, maybe I'll find a cheap classified ad for a 6th gen. Either way, thanks a lot bro, greatly appreciate your help.
