Bluescreen - Trace the last steps back and undo any changes:

If the blue screen appears shortly after the installation of a program or a driver or whatever, or if changes have been made to the system, then we suggest to either reset the system to the point in time at which the changes have not yet been made. Alternatively, if you still have access to the system, without the blue screen coming back immediately, then undo any changes you made and restart the system. Since Bluescreens love the moment of surprise, an extensive testing of the system is necessary afterwards. So use the system a few days as you did before and then you have, if the blue screen does not appear again, without major effort, the error is limited on the one hand to a misbehaviour of the software and on the other hand, to one of the steps carried out before. If the change to the system, whatsoever kind of changes, was important to you, it is necessary to repeat every step. Repeat one step at a time and test the system again for a while before performing the next step. If all steps are successful afterwards, then a temporary disturbance can be assumed here. However, finding the reason for a temporary misbehaviour is extremely difficult and may not be worth the effort. But if this is not the solution for you, then read on.


Check Windows system files for errors:

Many errors indicate that the system files are incomplete or even incorrect. To ensure that your system files do not contain any errors, you can do the following:

  • Press and hold the [WINDOWS-button] and additionally press the [X-button].
  • Then click on "Command Prompt (Administrator)" or "Windows PowerShell (Administrator)" in the menu that appears at the bottom left.
  • If you are asked whether you really want to execute the action, please confirm this with "Yes".
  • Now enter the following without quotation marks and confirm with [Enter] afterwards: "sfc /scannow"
  • The system is now getting checked for faulty or missing files. If damaged or missing files are going to be found, they are automatically reinstalled via the Windows updates.


Update driver:

Bluescreens can also be the result of a faulty driver, or an outdated driver that has become incompatible due to innovations of the system. We recommend that you completely install or reinstall the provided drivers from the manufacturers website of your device or your installed hardware. This ensures full compatibility. Some manufacturers may require additional model information before you are forwarded to your device's drivers.

These informations can be displayed via the following steps:

  • Press and hold the [WINDOWS-button] and then press the [X-button].
  • In the menu, at the bottom left, you will see a point named "Windows PowerShell".
  • Click on it and enter the following without quotation marks in the fresh opened console and confirm with the [Enter-key] afterwards: "Get-WmiObject Win32_BIOS".
  • You should see the rows "SMBIOSBIOSVersion" and "Name" with further information, which should be identical. These two rows contain the necessary description to continue on the manufacturer's website.

Please note, that it is your responsibility to update drivers. They are not automatically kept up to date. We therefore recommend visiting your device's driver page from time to time to check for newer versions.


The error can also be with the hard disk, which does not necessarily mean, that the hard disk is broken. Checking the hard disk and recover defective sectors may have been the reason for the bluescreen and after successful repair, make sure that the bluescreen does not come back, by testing the system.

Check hard disk for errors and bad sectors:

  • Press and hold the [WINDOWS-button] and additionally press the [X-button].
  • Then click on "Command Prompt (Administrator)" or "Windows PowerShell (Administrator)" in the menu that appears at the bottom left.
  • If you are asked whether you really want to execute the action, please confirm this with "Yes".
  • Now enter the following without quotation marks and confirm with [Enter] afterwards: "chkdsk /f /r /b"
  • The "/b"-part repeats the process to check for any remaining errors. You can remove this part if you do not want a repetition.
  • If you want to apply this command to the hard disk on which the system is located, you will be informed that the check will take place at the next reboot.
  • You can also check other hard disks and external storage media with the command, by placing the assigned letter of the respective hard disk or storage medium, that you want to check, between "chkdsk" and the first "slash command". For example "chkdsk D: /f /r /b". Now the second installed hard disk or the connected storage medium is getting checked.


If a blue screen still appears after all this, it is time to check if the RAM is responsible for this. Checking the RAM is an actual part of the typical procedure of most users. Please note, that, if the error message due to the name indicates, for example, the RAM, then this only means that the error occurred there, but it does not mean that the error is there or can be found there.

Check RAM for errors:

  • Click on the "Windows-icon" with the mouse in the lower left corner and, without further ado, write the following without quotes: "Memory"
  • After a short moment, you should see the following "Diagnosing Computer Memory Problems" message.
  • Click on it and then click on "Restart now and search for problems (recommended)" in the window that opens.

The computer will then restart. Please run the program until it is completed. Please note that the check can take several hours.


Memory error-free but bluescreen still there? Then there are the classics for troubleshooting, which, even when writing the instructions, is the last you think of, because it seems so absurdly unlikely but actually leads to success for one or the other:

  • Virus scan with Windows Defender or your preferred antivirus program.
  • Malwarebytes Adwcleaner - to search for adware - We do not want to advertise, but in our opinion, this is the most effective program for detecting adware.
  • Check for and install new Windows updates.

If the error still exists after all these solutions, then I have another solution for you, which is a little bit more radical, but more precise. You will find this in the following article: "Determining the source of a Bluescreen (link follows - instructions not done yet)".
