Windows 10: My computer is broken

So basically I wanted to install an update, and I am on the windows insider program. I don't have safe mode on. I had tried a couple of times, and every time it would tell me that the login was unavailable. After I forced the computer off and back on again it would work. But the update wouldn't update. This time after I did it, I tried my usual method and it didn't work. I got to the lock screen and it will tell me that it doesn't work. I shut it down and turned it on and got a blue screen with options to troubleshoot. At that point I wanted to exit the insider program so I pressed reset windo

Is my graphics card broken?

UPDATE: Please see here.

I have a Sapphire HD 4830.

When I boot into XP all is initially fine and I am able to see the desktop.

However, when I click on the start bar and navigate a few steps, I receive an immediate white screen of death and a total irrecoverable lock-up.

I am confused about what this could mean and I would be grateful for any suggestions on the best course of action to test and repair the problem.

Does this sort of issue suggest that the graphics card is irretrievably broken?

 

Is my computer microphone broken?

My computer microphone is not working. I have a Windows 10. Windows Version number: 19045.3271

• When nothing is plugged in or I plug in my wired earphone, the voice recorder shows that "To get started connect a microphone"
• I tried updating all the drivers still not working
• I tried using my phone as a webcam & microphone still not picking up any sound (my phone is fine)
• I tried using a wired headphones, but nothing
• BUT when I connect to my Bluetooth earphones and speak in it, Google Meet or Skype can pick up my voice.

QUESTION Can these factors determine whether my computer's mic is broken or not, thank you! & Can the computer record sound if I connect my phone as a external mic even if my computer mic is broken?

 

Realtek audio broken with update, Also microsoft chat is broken

My audio is ruined with this last update, i've done every step and recommended action listed by microsoft and every suggestion on the first 20 pages of google search. Realtek is no longer showing up anywhere, like microsoft disabled it, microsoft chat is
also broken, requesting to speak with a human brings you to a couple options, all of which are broken and clicking on "chat" closes the window and nothing happens, this is absolutely disgusting, i've spent the last 4 hours trying to get my tablet, my audio,
and microsoft support to work.
