I'm having an issue where my PC will reset when I play XCOM 2, but it's only on the final mission have I had this come up now and it seems to only happen when I load a save on said mission. If I start from the beginning of the mission it seems fine, but if I save then come back then the issue seems to arise. I tested with other games and this has not happened.

It happened again today when I was playing Star Citizen but my PC didn't reset until I minimized the game. This happened twice. The game runs fine (not smoothly but it is an incredibly demanding game) and my temps seems fine. GPU in the 70s, and CPU in the 60s. This being on high settings.

Once the game gets minimized it takes a minute before the PC resets.

My theory is that it's the PSU which I believe has been faulty. My build is about 3 years old now and when I first built it, the PSU would shut down (no reset) whenever I played a game too long. The solution was to turned the PSU so that the fan faced inwards. I don't know why this fixed it.

Another issue to toss out there to see if it helps is my CPU when dusty, will heat up and causes teh graphics driver to crash. I could tell it was the dust because when I used compressed air to clean it, it stopped doing this. A friend of mine said if the CPU was the problem then the comp would reset but...I don't know. The whole thing has left me without a clue.

I'm already planning on doing a little upgrading but I want to make sure the money is spent in the right place.

Thank you in advance.

Corsair 650watt

Sounds like you probably have one of the corsair low end builder series power supplies. I would bet the farm that it is the root of the problem. I see a dozen posts a day with this exact issue, and have never seen this issue not solved by a new power supply.

What happens is, each component of your PC depends one 12v power. Well, once the GPU starts really kicking in it wants more amps on the 12v rail. When it doesn't get the amps, it crashes. The PC remains "on" in this weird limbo state, and some even recover completely, some don't, but long story short is that the GPU is starved of power before the CPU and motherboard are, so it is the device that fails.
