Hi Chuck,
This happens if you assembled a computer with different hardware parts with different brand and specifications. Some motherboards do not work with other devices and recognize it as unknown. Hence, making your whole computer setup became complicated or not to work at all.
Regardless if you perform any software troubleshooting or reinstall an operating system, blue screen errors will still persist due to hardware incompatibility on your computer setup. Having a clean install is a fresh start and should have no errors anymore unless the operating system files became corrupted again.
You will need to determine what your motherboard wants before looking on the software side. To avoid a complicated setup, we suggest that you contact your computer manufacturer and confirm what are the hardware parts that are compatible with each other (CPU or processors, hard disk, RAM, power supply, network adapter, sound card, video cards, etc.).
Once they provided the information, have a clean install of Windows again and tell us what happens. Usually, they will suggest to use hardware parts that were approved by them for standard computer setup.
Let us know if you need more help.
