Question Intermittent crashing in multiple games for months, need troubleshooting help

[grstr]

Specs:
Windows 10
Ryzen 5 5600
MSI B550M Pro-VDH
G.Skill Ripjaws 32gb @ 3600mhz cl16
ASUS RTX 2070/MSI GTX 1080
840 EVO 120gb
860 EVO 1tb
Crucial P5 Plus 2tb
WD Blue 1tb
Corsair CX500

Been running into issues with intermittent crashes to desktop in multiple games over the past few months.
When checking the Windows Reliability Monitor, at the time of each crash, there is usually a Hardware Error report followed by the game that stopped working.
The reports of the games usually include the exception code "c0000005."
Sometimes the faulting module is d3d11.dll.
Stability seemed improved after switching to known good GTX 1080, however tonight had another game crash.
Temps seem fine while gaming and during stress test.
After some troubleshooting of the GPU and RAM, I'm led to believe that this is a problem with either the mobo, CPU or power supply. I don't remember this being a problem before I swapped to the Ryzen 5/MSI board last summer.
Not really sure how to confirm if those other components are bad, though.

Things I've tried:
Use known good GPU
Turning off XMP
Memtest86 overnight (passed)
Clean reinstall of graphics driver using DDU
Use DISM and SFC tools
Stress test GPU (Superposition @ 8k optimized)

Start with a quality 650w psu.

Start with a quality 650w psu.

Thanks for the suggestion, is there anything else I can try while I don't have access to a 650w psu?
