Yea, I went through everything and have WinDBG to view the mini dumps which didn't really give any clues. There seemed to be a mention of nVidia in one of the dumps but with other problems, it didn't really fit. I'm hard wired only into the motherboard.
As Lanx said, I don't have built-in Wi-fi, but I've updated all the drivers for the motherboard like Chipset, and made sure I'm on latest BIOS firmware. I've replaced the power supply, and SSD, and swapped RAM sticks around after a clean memtest86 to just make sure. Temps according to HWW Monitor were all fine even under load, as a thought I had was maybe the AIO pump or something went bad and it was freezing due to heat, but again that wouldn't be causing DPC Watchdog Violation blue screens.
I forgot AM5 had come out and while the speed boost from the new CPU and DDR5 would be nice, I think I'll just look up prices on that 5800x3d.
