Alright, so I'm going to include a bit of background in case it is relevant. So back in November or so my computer crashed and started booting up with bluescreens which prevented me from launching Windows 10. Long (very long) story short, the only thing that ended up working was installing Windows 11 through usb. Automatic repair and resetting my PC (even full, complete resets) wouldn't work. However, when I upgraded to Windows 11 my computer began to run incredibly slow without using system resources, as well as bluescreening whenever I turned on my PC (which I could bypass by pressing escape to go to BIOS then promptly leaving it). I am not sure if these two things are connected, but I assumed it was a Windows 11 issue. After some struggles, I finally managed to get back to Windows 10 a few weeks ago. However, reverting to Windows 10 did not fix either of those issues, things continue to run really slow, and the bluescreens still occur.
I decided to start by attempting to tackle the bluescreen. I have seen most recommendations suggesting running startup repair with a recovery drive usb, so I decided to try that. However, when running the repair, I get an error message "Startup repair couldn't repair your PC" pointing toward the SrtTrail.txt. Looking at the log file I found the root cause of the failure being "Boot critical file C:\EFI\Microsoft\Boot\CiPolicies\Active{ ___ }.cip is corrupt" (numbers in curly brackets omitted for brevity, I can include them if necessary). I tried for instance checking this article and trying each solution, but none of them seemed to fix the problem.
Is there anything else I might be able to try that could fix this issue? Thanks in advance for any help you can provide
