Whenever I booted up a game I got weird artefacts on screen. I was then given a BSOD and an Nvlddmkm.sys error along with Driver IRQL not less or equal. I then opened up my pc as I remember that I opened it a couple days ago and maybe I forgot to plug something in. I found that the GPU was not fully set in the PCIE slot. Before this, I reinstalled windows and the same artefacts happened. After I properly set the GPU into place, it worked fine in game with no artefacts until a day later it just shut off with the same error messages or whenever I made contact with the pc case. Now I can still play games but if I play for too long it will show the BSOD error again. Will I need to buy a new GPU?
