Hey there! Thank you so much for responding and giving me help.
May I ask if it crashes when you play a specific game or all games?
It would crash/freeze on all kinds of games ex Hearthstone, League, Sekiro, it would sometimes even crash while i was streaming a movie over Discord.
But now after I started fixing, I've only tested with League of Legends because I thought playing games from the external harddrive was causing the crash.
Do you have desktop beautification software like wallpaper engine installed, and if so, turn it off first.
The first I did ironically was remove Wallpaper Engine, but then I don't know what came over me and I put in TranslucentTB to make the taskbar transparent.
I uninstalled that, and I did a clean boot. After ~2 hours of playing League on clean boot, it would have definitely crashed by now, but it seems to me it doesn't crash anymore.
I will test to see which one does this, but if you could check out these pics below of the services I disabled and see if any of them stand out to you in some way.
