I'm not having any thermal issues, drivers are up to date and just did a windows reset because my game was crashing before that issue was fixed with the reset. Upgraded my PC with a 7900xtx and 4k monitor from a 3060ti afterward my breaker was tripping a lot. Got a new PSU and new Ram wasn't the issue. Got a new circuit breaker that fixed it now my computer is crashing and restarting only when I'm playing 4k in Marvel Rivals. Switched to my 1080p monitor no more crashes but, I'm having a issue where my screen will randomly black out and go back to normal after a second. Ideally I want to play on my 4k monitor what could the problem be?

-Circuit breaker is new and my computer is no longer tripping the breaker.
-I did use DDU when swapping GPU's
-Did a windows reset to fix Marvel Rivals Game crashes. (solved it)
