So shortly after my last post, I tried some combination of command prompts suggested by my dad. They didn't work, but they worked just enough to get SupportAssist to fully load instead of hang, and I was able to get my PC fully reset. It's now working, albeit a little slower. Thank you for trying to help!
Friday I was on my computer working on flashcards. In the middle of creating one, my PC crashed. Confused, I booted it up again thinking maybe it just auto-updated and restarted. It started booting and then froze on the alienware boot screen. I watched it for a few minutes and then when nothing happened I powered it off and tried again. SupportAssist OS Recovery tried running, and it did for maybe a minute... and then IT got hung up. Rinse and repeat a few more times. I ran a diagnostic and it said everything was fine. I tried resetting to a backup, and that worked until it the end where it said there was error. Any attempts after to do so resulted in it hanging up. I tried to do a complete reset. That hung up as well.I tried creating a bootable USB drive to reinstall windows from, and it wouldn't recognize the drive was there (though I could have set it up wrong) If I remember right from the diagnostic I do think I noticed it said that the SSD Card wasn't installed when reading over everything?? I don't know what to do at this point besides a repair shop and they can't look at it until at least tomorrow.
