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.

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

 

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?
