I have a PC (Dell Inspiron 5675 - Windows 10, 32GB RAM, AMD Ryzen 7 1700 Eight-Core Processor 3.00 GHz, Samsung SSD 980 1TB, TOSHIBA HDD DT01ACA100, Dell PSU AC460AM-01) that is approaching two years of use. I first noticed maybe a couple months ago that an open-world game I like that also demands a lot from my computer was starting to make my fan go into overdrive, and over the course of a few days it progressively got worse to the point where most of the games I played would inexplicably crash after causing a spike in my computer's power usage. I haven't had much free time recently to resolve the issue, so unfortunately I can't remember any specific events that would cause any damage to my computer, but I did manage to make it a little better (which I also don't remember how), and now I can confidently run most apps and not fear crashing with the exception of games like GTA and Slime Rancher, I believe due to the fact that my computer can no longer handle loads that big. I should note that at least for GTA, my game also almost always crashes if I tab out then back in for any reason. I have been searching for an answer all day (I have tried rebooting my games and pc, making sure I'm using dedicated instead of integrated graphics, using different game resolutions, greatly reducing graphical quality, checking for updates, and so much more), but nothing I found has solved it. Can anyone please help my fix this or at least locate the source of the problem please?
