A Puzzling PC Crash Problem

For about a year and a half now I have been trying to self-diagnose and fix an issue I've been having with my PC. One day while playing Valorant, my computer suddenly crashed out of nowhere.

"No big deal" I thought.

I was dead wrong.

The crashing consistently happened every time I played any game that was even slightly demanding towards graphics (only exceptions being Minecraft and Roblox). One of the things I tried to solve the problem- cleaning it, actually stopped it from happening temporarily leading me to believe there was an issue with thermals. With that insight I tried replacing a few different things. Firstly the case (I was using the case that came with the pre-built so the thermals in that weren't great). Swapping the case actually solved the problem for a bit until it started happening again. So then I replaced the CPU cooler. No real difference there. I even swapped the power supply out which seemed to work for a bit only for it to start crashing yet again. I DO NOT KNOW WHAT THE DEAL IS WITH THIS THING. Only thing I can think of is that maybe something is wrong with the fan on my GPU but I'm not sure if that would cause this. But one thing I do know is that when you dust out the computer, the problem does stop for a little bit only for the problem to come back.

Any help or insight would be much appreciated

Thanks!

When you swapped out the psu with another..what were the spec's on that psu?

Originally it was a 450W unit. The first crash happened while that was still the PSU in my system

You mention that when you dust the machine the issue stops for a while then comes back ,do you have a box fan you can use to test the issue? Just remove the side panel on the computer and place the box fan where it can cool the machine. If the issue does not come back during this period then I'd suggest a bigger exhaust fan in the computer...

I see that when you do the Speccy snapshot it details my IP info as well

Bruce said:

it only shows your LAN IP address, not WAN addresses.
in other words, IP's that only pertain to your network, that face inwards, not outwards.

even if someone was so inclined, there is nothing in the Speccy report that would help them hack into your PC.

oh so is the LAN IP like your private IP and the WAN is like your public one?
