Windows 10: Something is wrong with my windows security If not the entire computer

Windows security is displaying in a weird way, not like it used to before. The dark mode appears to be broken somehow.The first thought appears in my mind was some kind of malware or something, i tried to use the windows security itself to quick scan the computer, it returns nothing. Then i installed malwarebytes to scan it again to make sure, it did returned 8 detections which i quarantined 7 of them the other one is false positive. I then restarted the computer but still, nothing has been fixed.This broken dark mode thingy also appears on google chrome which is set as default browser/i sa

How do I reformat entire computer?

Update:

• I probably should have taken better notes on what I've already tried
• I created the USB flash drive as directed in #26. That did indeed install W10
• I now am at the same point that I described in my post #6, with my drives still being dynamic rather than basic and the following exceptions from my post #6 (not sure)

- Now all of my data is on the C:\ drive rather than the various folders like "My Documents
- I apparently need to reinstall my display driver. The display is wonkey (circles are ovals) and I can’t seem to adjust using the settings menu.
- Other partitions that came installed with my HP notebook like System, Tools, and Recovery now have different drive settings

So I’ve come almost full circle except with a few steps backwards. I’ll try more carefully to follow Post #2 and #7 as suggested. Possibly I missed as step with those earlier. I’ll also check with my other software to see if there is a simpler way to revert my computer back to the way it was out of the box.

 

The security account manager (SAM) or local security authority (LSA) server was in the wrong state to perform the security operation.
