BSOD after playing CSGO and TF2

So I'll start by saying in the previous 2 months, my computer has gone haywire and after spending lots of time trying to find the problem, I figured to just leave it and left it sitting for 2 months.

2 Months later, I boot it back up, and I'm able to play a game of TF2 completely fine, even download CSGO and play a few rounds.

But 3 days later, CSGO crashes on startup, and then it finally starts, but I get a BSOD a few minutes in. Then, I restart, try to play a game of TF2, and then when I just quit the game, I got another BSOD. Attached is a zip of one of the minidumps that was saved in the minidumps folder, the other wasn't saved for some reason.

Thanks in advance.
