Windows 10: PC update caused black flickering screen not with task manager and lost WIFI driver.

I’m at my wits end. I have what was an incredibly reliable HP PC which was ruined by a new Windows 10 update. It started by causing a flickering screen which i read up on troubleshoots for doesn't flicker the task manager box when opened but you cannot access the task bar so you cannot run anything and cannot even restart or turn off, can only do so via power button. I rolled back the update via “choose an option” blue screen and it worked. I then disabled updates because I had tried this previously and it would auto update and the same issue would arise again and again.However last night I

Screen flicker and hangup on desktop screen

The short term fix for me was to roll back to Windows 7. I did not have the time to work through the issues but will try again in a week or so. I had a call in to the Microsoft Answer Desk and got a call back after I rolled back. Pasted below are the suggestions
to attempt find the problem. In my case, I suspect Norton was the culprit since that was the common product on both my desktops and I was not seeing a flicker in Task Manager window.

From the Microsoft Answer Desk:

Here are the Steps for the Flickering issue.

If we see the screen flickering after sign-in there are two possible causes - apps causing Explorer to crash, or display driver issues.

To start, press this key combination: CTRL+SHIFT+ESC

If this opens Task Manager and that window is NOT flickering:The likely cause is Software Compatibility issue causing Explorer.exe to crash repeatedly.

• Use the File, Run option in Task Manager to open additional tools as-needed. Be sure to check the box to run tools as Administrator. These could include:
  
  appwiz.cpl: Opens Programs and Features
  
  compmgmt.msc: Opens Computer Management
  
  cmd.exe
• You can search for crash events in the Event Logs and find if any third party DLLs are the faulting module in the Explorer,.exe crashes Or uninstall software that is likely to include shell extensions.
  
• If removing software does not resolve the issue, use these commands to repair Windows:
  
  dism /online /cleanup-image /restorehealth
  
  sfc /scannow

We have reports that removing these apps help resolve the issue:

• Norton Antivirus
• Other AV solutions
• iCloud
• IDT Audio (faulting module IDTNC64.cpl)

If Task Manager is flickering, or it didn't open, proceed with display driver troubleshooting:
The likely cause is a display driver or display hardware issue.

• Boot to Safe Mode with Networking.
• Use the same steps here as for Black Screen issues - if dual chipset, disable built-in graphics, if still flickers, try with only the other chipset enabled.
  
• If this does not work, or there is only a single chipset, uninstall the device and remove the driver software.
  
• Then boot into Windows and update the drivers to the latest from the manufacturer.

Windows 10 pro 1607 64-bit Screen flickering issue.

Hi James,

I appreciate you for trying some steps in order to get the issue fixed.

Screen flickering in Windows 10 is usually caused by incompatible apps or display drivers. To determine whether an app or driver is causing the problem, check to see if Task Manager flickers. Then, based on that information, you'll need to either
uninstall the app or update the display driver.

Open Task Manager by pressing the Ctrl+Shift+Esc keys on the keyboard at the same time. If that doesn't work, right-click the Start button in the lower-left corner of your screen and then select
Task Manager.

• If Task Manager doesn't flicker, an app is probably causing the problem.
  
• If Task Manager does flicker, a display driver is probably causing the problem.

Please revert if the screen flickers.

Thank you.
