If you swapped motherboards without doing a clean install, there is no telling what random errors you could get. A clean OS install, not an upgrade like you did with Win 11 is recommended.I have installed nothing new. Had been having troubles Locking up and freezing. Tried every combination of swap out mem - Vid . everything other than PS. I replaced MB Processor /
X570 AORUS ELITE WIFI (rev. 1.x)
It has been running better but still RUNDLL error.
I upgraded to Win 11. Still persist.
