So in October of this year I bought the RX 5700 (XFX Blower model) at Best Buy because It was on sale, and I traded it for a Msi GTX 1660 ti. when I got it was running perfectly fine siege, apex and cs-go but in November I bought Modern Warefare as it was on sale and that's when the issues started to occur... i was playing the campaign one night and i was towards finishing it and all of a sudden the screen went dark. everything else was still running the case fans, the RGB etc. and I reset the PC and was running fine the next day I played multiplayer and it was fine for a while until it started having the same issues again and the monitor screen went dark. fast forward to today since a couple of weeks after that happened i have increased the fan speed and i still keep getting the same issues as before. The problem never occurred in siege but now as so as I load into rainbow six siege It makes a noise and sometimes it lets me play or it crashes and takes me to the loading screen as well as everything else on chrome or playing MW it goes into a dark screen. I don't know what I should do as this is really affecting me as this is my first ever PC build and I have invested a lot into this computer and I don't know if its a software or graphics card issue. here are my specs.
