Recently i started playing some shooters again and noticed that in csgo pc sometimes crashes and pc fans rev ups to the max imediatelly, but didnt pay much attention to it. Previously i played LoL and had no problems. Few days ago i added fortnite to the mix and everything was fine at 1080p resolution. Today finicking with the settings i noticed that the game was at 1080p while i have 2k monitor, so changed resolution of the game to 2k and imediatelly crashed. After that couldnt get into fortnite anymore, it crashes pc imediatelly after loading screen ends. I decided to do a stress tests, and with cpu everything seems fine, but with gpu, pc crashes imediatelly upon pressing stress test button. Any ideas what should be my next steps, or how to fix it?
