Anything we missed to try from this list?

- Boot with Last Known Good Configuration (F8 menu)
- Restore to a prior date (System Restore) - System Restore
- Scan for malware (Malwarebytes Anti-Malware free)
- Try a clean startup Troubleshoot Application Conflicts by Performing a Clean Startup
- Check if explorer.exe is running and start from CTRL+ALT+DEL (task manager - new task)
- Verify in registry: HKEY_Local_Machine\Software\Microsot\Windows NT\Current Version\Winlogon to make sure 'shell = explorer.exe'
- Follow SFC /SCANNOW Command - System File Checker
- Try loading defaults in BIOS

I tried under F8 ===> Repair Computer===> Command Prompt ===> Works OK

Here is the result:

- Boot with Last Known Good Configuration (F8 menu) ===> Black screen with cursor in the middle
- Restore to a prior date (System Restore) - System Restore ====> Already reported in previous reply
- Try a clean startup Troubleshoot Application Conflicts by Performing a Clean Startup results in

Clean Start up

D:\Windows\System32>runas /user:administrator msconfig
Enter the password for administrator:
Attempting to start msconfig as user "MININT-84TH5FG\administrator" ...
RUNAS ERROR: Unable to run - msconfig
1060: The specified service does not exist as an installed service.

- Try loading defaults in BIOS - F2, f9, f10 ===> Black screen with cursor in the middle

Follow SFC /SCANNOW Command - System File Checker ====> Already reported the outcome No [SR] tag with errors

Check if explorer.exe is running and start from CTRL+ALT+DEL (task manager - new task) ===> CTRL+ALT+DEL not responding

- Scan for malware (Malwarebytes Anti-Malware free) yet to try. Will this find something, that was not found in Windows Defender offline? Do I able to run this from USB as offline?

Thanks for your input.

Update.

I tried with Farbar Recovery Scan Tool x64

I am attaching FRST.txt for your review.

I tried your steps. Do you mind, sharing your insight? What is happening here?

I did the Fix using Farbar Recovery Scan Tool. It created Fixlog.txt

I booted the computer in normal mode. ====> Same situation Black screen with cursor in middle.

I ran the scan using Farbar Recovery Scan Tool . It created FRST.txt I am attaching both FRST.txt, & Fixlog.txt for your insight.

Is this situation caused by infection (virus/malware), Hardware issue, BIOS, Memory etc? It will help others as well.

My apologies for the delay. You caught me at a bad time when you posted to that other topic to get my attention. Just too many irons in the fire.

This could be caused by any number of things you mentioned above.

Please disconnect any peripherals (if any) besides the USB flash drive before proceeding.

  • Open notepad (Start orb > type notepad into Start Search > chose notepad from list.

Thanks for looking into my issue among too many irons in the fire. I asked that question to learn about source/cause, so I can keep away from that source upon fixing this issue. I did not install any new device or open any email attachments. My son was playing video games from sites such as Steam clients, team speak, chrome, & counter strike etc. Youtube videos

As per your suggestion, I am attaching the fixlog.txt for your insight.

Thanks for helping.

Awaiting for next steps.
