Windows 10: Screen gets darker shortly after startup

When my computer starts up after being shut down or restarted, shortly after the login screen appears the screen will suddenly get darker. I have tried the following to fix it already without success:

• I have updated my video card drivers.
• I have updated the monitor drivers and the software for my monitor.
• Through my monitor's software, I have turned off any automatic brightness adjusting features. (I've also done this through the options on the monitor itself.)
• I have turned off adaptive brightness for Windows.

This has been going on for many months, maybe even a year. Any other suggestions would be appreciated. I am getting into a field where I will need to do color-sensitive work on this computer, so this needs to be fixed. Let me know any information you need about the computer and monitor and I'll provide it.

Blue Screen Error shortly after startup.

Hello John,

Thank you for posting your query on Microsoft Community.

As per description, you are getting blue screen error.

We are unable to open the link provided by you.

I would appreciate if you can provide us the following information to help us understand the issue better?

• Have you made any recent change on your system prior to this issue?
• What is the make and model of your system?
• Are you getting any error message/ error code on your screen?

I would suggest you to follow the methods given below and check.

Method 1:

Step 1:

To diagnose whether this issue occurs in
“Safe Mode”, let’s reboot the computer in safe mode and check if the issue appears there as well.

Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. This helps us in identifying whether the issue is due to some
third party programs conflict. The word Safe mode appear in the concern of your monitor to identify which windows mode you are using.

Follow the steps given below and check if that helps.

• Type settings in search and click on Settings.
• Click Update and recovery, and then tap or
  click Recovery.
• Under Advanced startup, tap or click Restart now.
• Once your PC restarts, on the Choose an option screen, tap or click
  Troubleshoot.
• If you don't see the Startup Settings option, tap or click
  advanced options.
• Tap or click Startup Settings.
• Tap or click Restart.
• On the Startup Settings screen, choose the
  Safe Mode.
• Sign in to your PC with a user account that has
  administrator rights.

If the problem does not exist in safe mode, try to perform a clean boot and check.

Step 2: Perform Clean Boot.

Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. Check this issue in clean boot state.

• Press Windows key + X key. And select Run.

• Type msconfig in the Run box and hit Enter.
• On the Services tab of the System Configuration dialog box, tap or click to select the
  Hide all Microsoft services check box, and then tap or click
  Disable all.
• On the Startup tab of the System Configuration dialog box, tap or click
  Open Task Manager.
• On the Startup tab in Task Manager, for each startup item, select the item and then click
  Disable.
• Close Task Manager.
• On the Startup tab of the System Configuration dialog box, tap or click
  OK, and then restart the computer.

Note: After clean boot troubleshooting step, follow the section "How to reset the computer to start as usual after troubleshooting with clean boot" in the provided link to return your computer
to Normal startup mode.

If issue still persists try method 2

Method 2: Install Windows updates:

I would suggest you to refer to the article below and install updates.

A blue screen shortly after startup

As with thewarder500 (asked Aug 9th 2015) I have been getting a blue screen shortly after startup with the message
KERNEL_SECURITY_CHECK_FAILURE. This started about 2 - 3 weeks ago and happens most times but not all, (before the big update) but unlike thewarder500 I have not changed my setup nor added any hardware.
