Back around October of this year I noticed my PC began crashing regularly with my old GPU (Radeon 5700XT). It got to a point where not only games, but my entire PC would crash. I always assumed the graphics card was the problem and was frustrated with the GPU shortage. When I finally got my hands on a 3070 I believed all my issues were solved, but once again my system has started crashing in games again, luckily it hasn't been the whole PC yet. My Windows and graphics drivers are both up to date and I'm no longer sure what to do, any help would be appreciated!

I just got another graphics card because my old one kept crashing my games and PC. I thought my problems were solved but my new graphics card is starting to crash in games as well. As far as I can tell it is not overheating and surely I couldn't have gotten a faulty card. Is there something else in my PC that I need to fix or replace?
