I did replace the power supply is 2021 from the original Corsair Builder cx600 to the current Corsair RM650.
I have moved to Linux Mint with Windows support soon being discontinued, so I'm also learning how Linux works at the same time as dealing with crashes. I'll look into the themal paste as well since that is an easy thing to replace.
Just wanted to mention, because it's often overlooked, check the thermal paste on your GPU as well. My wife's system was crashing constantly in games and it was driving us crazy trying to figure out why. Then, I pulled the GPU cooler and found the thermal paste was more "powder" than "paste". Cleaned the old paste off, applied new paste, and the system ran like a dream for another year or so before she upgraded the GPU.
So I got a tube of thermal paste and redid the GPU and CPU. It was pretty crusty on both, so far after about 30 mins running 8 different tabs of YouTube concurrently the fans barely turned on versus that crashing the computer after 5 mins.
I'll run some proper tests over the weekend. Do a bunch of benchmark tests on beyond all reason to see how them temp goes.
