Question At the end of my wits! (infinite boot loop)

Hello lads and gals,

I'm honestly at the end of my wits. A few days ago, my old system suffered from what I believe a power surge. While I was eating dinner, I noticed my system all of a sudden restarted twice in a row after which it wouldn't even give me any display. I cracked open the case and looked at the motherboard qcodes— it gave me somewhere in between the range of 50 and 58, which according to the motherboard manual were cpu errors. This was an i7-4790k.

Well, I decided right then and there that I would upgrade my system, thinking it just kind of died on me and the problem would go away, so I went out and bought an i9-9900k, Gigabyte Z390 Aorus Ultra, 2x8gb of Trident RGB ram sticks and a be quiet! Dark Power Pro 4 cpu cooler, totaling 965 euro. Now, I unpacked everything and installed the ram firmly, cpu is correctly installed with new thermal paste, and the cooler is correctly installed. I did every step according to the manual. Loaded it up in the case, all good on the standoffs and booted it up. All is good, I get a display and then it restarts and ends up in an infinite boot loop at the bios. I managed to update said bios, nothing. Double checked everything, nothing. Reseated my ram, nothing. Tried it with just one stick, each, nothing. Went to a renowned pc hardware shop and had it looked at, nothing. They reinstalled Windows, completely wiped my harddrives, nothing. Every cable is tightly and correctly put in. Even adjusted my cpu cooler, nothing. It all appeared as if it was fixed in the shop itself, so they gave it back to me and I paid 150 euros for that. I come home, spend five minutes on the pc and it reboots again!

Okay so, I changed my power strip and wall socket at home, didn't do anything. So, here I am now. I'm at a loss here. The only constant is my case, psu and harddrives. I have no means to test if it's my psu, but what do you guys think? I had a look at the troubleshooting thread as well.

Please help.

Ok so we have

MB Gigabyte Z390 Aorus Ultra
Ram 2x8gb of Trident RGB

What is your main OS drive? GPU? and most importantly PSU make and model.

Nowhere in that post did you say you bought a new PSU, if you had a power surge, an both your computers old and new or having issues booting i would suspect the PSU as the root of the issue.

I believe I had a power surge. I'm not 100% sure. Sorry, I'm typing on my phone, so it was a bit rushed.

My GPU is a GTX 1070, Windows 10 Pro and my current PSU is a Seasonic Focus Gold 850w. Those, along with my Samsung 860 Pro and Samsung 850 ssds and a regular hdd, and my case are the only things I haven't upgraded.
