Random Gigabyte Aorus Elite wifi 7 errors

I have a fairly good system I built last summer that has been running fine until a few weeks ago when the motherboard started to throw out random errors. From 46 to about 76 I'm getting a different error code on the motherboard every few seconds to a minute apart. I can't seem to replicate any specific error code.

But, the computer seems fine. I can play games at good frame rates and settings and the PCmark benchmarks are about the same as when the motherboard was not playing bingo. No diagnostic software (Samsung magician, OCCT, HWinfo, Adia64 trial) point to any hardware error and all of OCCT's stability tests show with no error or unusual temperature raise.

What else can I check? The error codes keep coming and checking them don't really illuminate anything. Should I just keep on using the machine until something shows itself? (While keeping exceptionally well backed-up.)
