Windows 10: Troubleshooting idle problems with no errors

I need help troubleshooting my Windows 10 Home PC. I have problems with it only when it idles. The problems are intermittent and hard to troubleshoot. Sometimes it will lock up after being idle for a while. Sometimes it won't lock up but the screen will not power off. Sometimes it behaves perfectly fine. There are no errors in the Event log, BSODs or memory dumps.


I have tried:

• Reinstalling Windows from image
• Updating all of my drivers
• Scanning for viruses and other malware
• Scanning and defragging hard drives
• Turning off most of my power saving settings
• Scanning for memory and other hard defects
• Stress testing for heat related problems

I am at a loss at this point. It is very annoying to constantly have to hard boot my PC if I step away for too long.


What else can I try?

The tutorials provided are just a list of troubleshooting steps. Use only the steps which apply to you.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.
