I upgraded my CPU and motherboard to Ryzen 5800x and aorus b450 elite a few days ago. After completing the build and turning the PC on I got a blue screen, disconnected the power cable and booted again. It worked, got into windows, all worked fine, put my PC into sleep mode and it worked fine the next day aswell. After restarting my computer I got stuck in another BOSD loop, disconnected my power cable a few times and managed to get back to windows, at this point I thought it was my Windows causing problems, since I hadnt done a clean install after upgrading. On the third day the BOSD loop got even worse, took me 10+ tries to get into Windows, I finally decided to reinstall Windows using the built in reset function on Windows 10. As soon as the PC restarted for Windows install I got a blue screen so the install canceled. After that I completely disconnected my main (the drive the drive that Windows installed) and only pluged in an empty drive and a memory stick, still constant BOSD loop.

The weird part is that once I managed to finally load into Windows everything was 100% working, no shutting down or BOSD or anything.
