Honestly I am kind of relieved this pile of cow flop has finally failed. If the many computers I have assembled over the years this one has been the most problematic. It was intended to be my last PC before going completely Apple. The PC demon must have heard me. I Realize now I will always need PC no matter how Apple it get.
Just learned a tidbit about the Apple Silicon CPU you will no longer be able to use Boot Camp to run Windows on a Mac computer.
Is the BIOS battery voltage OK? My desktop PC fails to boot if the voltage drops below 2.8V. A new CMOS battery should have a voltage c. 3.2V. Always load the BIOS defaults after removing or changing the battery.
