Trouble resetting windows

[BigFruit]

I recently replaced the motherboard on my system and initially tried booting from the same unaltered SSD I used with the previous motherboard. It booted but was very unstable so I did a system reset but it continued to be unstable and after a few restarts I got a page saying there was an error with a disk and press ctrl+alt+delete to restart which just brought me to the same page. I brought it to a pc repair place so they could diagnose the problem because I am very busy and thought it would be easier than diagnosing it myself. They said that my secondary drive (a 1 tb hdd) went bad and that if I run it without that and reinstall windows I should be fine. I removed the hdd and tried to do a windows reset, it restarted my system and then said it was preparing system for reset and was 88% done, it stayed on this page for a while and then all the loading bars stopped ticking and it froze. I left it in this state for about 4 hours and everything was still frozen up. I shut it off with the power button and now when I try to turn on the pc it goes to the window loading screen and wont do anything else. How can I format my ssd to reinstall windows?

normally if you swap motherboard you should reinstall windows 10. That is the cause of most of your issues. Did win 10 remain activated after the swap?

So now, easiest way to fix them is on another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB
change boot order in bios so USB first, hdd second
