Windows 10: My Computer Might Be Broken.

1 hour ago, my computer Dell Latitude E6520 was working fine. And all of the sudden, when I turned off and back on the computer, it showed a black screen with a cursor BEFORE LOGIN. Every 1-3 seconds, my cursor disappears and comes back with a blue circle. I tried performing a low resolution, and even did a Safe Mode with networking and command prompt and it stills shows the same issue. I checked the "BIOS Events" and "Thermal Events" and they show multiple problems like "Fan Malfunction" or "AC Power Adapter wattage and type cannot be determined" or "The amount of system memory has changed"

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.
