Windows 10: Screen flickering in File Explorer and commands missing

I built a PC a few months ago and installed windows 10 home edition on it ACTIVATED. Then i bought a second monitor. I connectedthe monitor and purchased and installed ASTER a multiseat software so that 2 people can work together on 1 PC. Everything was working fine till 2-3 months. But, then i started Mining for 1 week without stopping or turning my PC OFF. After 1 week later I faced flickering in File Explorer and missing commands on my second workstation. I tried disabling ASTER and updating my graphic drivers but that didn't work. This is happening only on my 2nd workstation monitor wh

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.

File explorer flickering


Not sure how to explain this.

When in Windows explorer I'll be looking at a list of files in the"details" listing method. When i run my mouse up and down the list of files the type in the file names flickers or jumps around if you will.

No idea why. I shot a short video from my phone

Thanks
