About a month ago I ordered a pre built from cyberpower going through best buy. Ever since I first plugged it in, it would crash 3-5 minutes after booting up. I find fixes and they do end up working but only temporarily, then after working a few times, they stop doing anything to help and then I have to find a new method to 'fix' the issue. Also, the PC bogs down HEAVILY right before a crash.

At first I would reseat the RAM and it would stop the crashing for a day or three, then start crashing shortly after booting to desktop. After about a week of that, reseating no longer worked.

Then, swapping the RAM sticks around would temporarily fix it just like reseating did, but after two weeks, this also stopped working.

The latest 'fix' I've been doing is power cycling (power cycling meaning I turn off the PC, unplug the power cord, turn off the PSU and then hold the power button down for 20 seconds twice, then replug everything and power back on) the PC, which has been continuing to work for about a month and can lead to zero crashes for 5-7 days before it inevitably crashes without BSOD.

This lead me to believe it was the PSU causing issues since most reviews said the PSU was pretty mediocre. I replaced it today and reran all cables only for it to solve nothing 🥲 $140 wasted.

Turns out, the CPU temperature spikes up to 106+ as it bogs down, right before crashing, but the strange thing is that it only goes to those insane temps on the random day it decides to crash again. Power cycle fixes this temp issue completely until it decides to show up again.

This is leading me to believe it could be a bad AIO pump, or maybe an air bubble in the system that somehow resolves after a power cycle..?

I don't know anymore, I could replace the AIO with a regular air cooler, which I prefer anyways, but that could lead to me wasting another $50+ and being stuck chasing more gremlins.

I'm still within my return window at bestbuy, so I'm thinking about just driving the 2 hours to the closest best buy and returning the whole thing and ordering separate parts and building my own (I avoided this because the prebuilt was on sale and cheaper than parting out, but is no longer on sale). Unfortunately I'd have to unhook and rerun the PSUs again 😭 But on the bright side I wouldn't need to buy another PSU..

I also repasted the CPU today and it changed nothing.

Any help or advice would be much appreciated. I'm so over this and about to give up on PC gaming again because my consoles just always work without this bs
