I recently upgraded my computer, changing the case, power supply, and graphics card. I accidentally plugged the wrong end of the CPU power cable into the motherboard but fixed it before powering on. There didn't seem to be any visible damage to either the motherboard or the power cable. However, I've had a couple of odd crashes while playing Marvel Rivals. The first crash made all my screens go black for a few seconds and then the Windows GUI seemed to restart. After that, I experienced a normal crash-to-desktop but was able to play fine afterward. I ran various benchmarks like Cinebench, FurMark, and SuperPosition, all of which returned normal results, but Prime95 did show a hardware error on one of the threads. I'm running stock BIOS settings except for the RAM, which I used XMP to reach its advertised speeds. Is this something to be worried about?

You mentioned that you didn't reinstall Windows after changing components. Sometimes, that can lead to instability if Windows is loading drivers that aren’t fully compatible anymore. Also, keep an eye on your temperatures during those benchmarks; overheating can cause crashes and errors. If things don't improve, consider a clean install of the OS.
It sounds like you might have a stability issue, especially since you got a hardware error during Prime95. This could suggest an underlying problem, possibly related to the new GPU or RAM settings. Since you did mention you upgraded from a 3070 to a 9070xt, make sure the power supply is sufficient for the new GPU too. Have you checked if all the drivers are up-to-date? That can sometimes resolve crashes in games.
