Following those steps didn't do much, though on my own, I've been trying to figure out what the problem is so I could figure out how to solve it. It seems that whenever I unplug my headphones from my computer before starting it up, or just by luck, I get past the Windows is Loading screen. I also noticed that whenever I load Ubuntu, the computer loads fine. I don't know if it's the hard drive or not, but I hope it's not.
This problem isn't exactly solved, but I am able to slightly use my computer again. I've had freezing issues, which were fixed with Select Startup, and boot issues, which are inconsistent... and now I'm having memory issues. It seems this is directly related to Windows Defender, even though it's not what's always using up my memory. Whenever I stop the SVCHost related to Windows Defender, the memory usage goes from 99% down to 25%, even though my computer still experiences slight freezes even though memory/cpu are both around 20%. I don't understand why it's doing this, and it would be nice to figure it out.
I did notice that Memory started getting used after I installed SplashTop Streamer. I don't think uninstalling it helped much on the memory side of things, though it is something I noticed.
Since there are so many problems, I don't know where to continue with this, or what kind of problem to even call it. It could be a Hard Drive beginning to fail, or a driver
conflict, or a bad program installation. Or it could be an audio issue, I've been having trouble with audio since I got this new computer. It could even be a conflict between Windows Defender and Avast, even though I don't have Defender do anything.
What should I do from here?
