Windows 10: A black screen appears for about 5 minutes every time after restarting and signing into...

A black screen appears for about 5 minutes every time after restarting and signing into Windows 10 PC. This has happened every time I restart and sign in; after 5-10 minutes, the desktop appears. I am using an Inspiron 15 7000 gaming laptop. Anyone had a similar issue?

:)

 

5 min delay on cold start between login screen and bg screen

One more thing to be considered; black screen 5 minutes after signing in only occurs with my admin sign in account; my wife signs in in a split second with her non admin account. So admin sign in account should be limited to solve this.

 

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.

Hi Muhamad,

You might be experiencing this issue because of corrupted system files or device drivers. To help us identify the cause of this problem, we would like to know the following information:

• Are you able to reach the sign-in screen when starting your computer?
• Have you made any changes to your computer before experiencing this issue?
• What troubleshooting steps have you tried so far?

In the meantime, we suggest that you perform the troubleshooting steps in the following link:

Troubleshoot black screen problems.

If you can reach the sign-in screen, we recommend that you start your PC in safe mode from the sign-in screen.
Safe mode starts Windows in a basic state, using a limited set of files and drivers. It can help you troubleshoot problems on your PC. Here are the steps:

• When you get to the sign-in screen, hold the Shift key down while you select the Power
  icon > Restart.
• After your PC restarts to the Choose an option screen, select
  Troubleshoot > Advanced options > Startup Settings > Restart.
• After your PC restarts, you'll see a list of options. Select 5 or
  F5 for Safe Mode with Networking.

Keep us updated on the status of the issue, and we will be glad to assist you further.
