The blue screen of death (BSOD) error is something that every Windows user finds sooner or later. It is a frustrating problem, since it is often difficult to solve and can arise from nowhere.
We will guide you through some basic tips on how to solve a blue screen error, as well as provide resources for specific blue screen errors. codes
What is a blue screen?
In case you're not sure, let's first review this important Windows term.
What is commonly called a blue screen of death is technically known as a detention error or fatal system error . This occurs when the operating system fails, which means that it encountered a problem that prevented it from running safely. When this happens, Windows displays a blue screen with information about the problem and then restarts.
Blue screens can occur for many reasons, which we will analyze next. Common causes of BSOD include defective drivers, hardware problems and operating system errors.
The newer versions of Windows are more stable than the previous ones, so you might not find blue screens too often. You should also know that a blue screen that occurs once is not necessarily a problem. Sometimes, Windows will get scared with a BSOD, and then it will work perfectly fine after rebooting.
Therefore, you should only delve into the following blue screen bug fixes if you continually hit a blue screen.
1. Consider your blue screen stop code
It is difficult to talk about how to solve blue screen errors without knowing the specific error you are receiving. Therefore, the best place to start repairing blue screens is to observe the real problem.
In Windows 10, a BSOD contains a sad face, along with a simple error message. Below this, you will see a link to the Microsoft blue screen troubleshooting page, a QR code and a field Stop code . If you wish, you can scan the QR code with your phone's camera to go to the Microsoft support page.
The most important part is to consider the stop code on the page, which will help reduce problem resolution.
2. Test the specific troubleshooting for your error code
Now that you know what your specific problem is, you can move towards the appropriate blue screen corrections. We have written articles on some of these:
These are not the only blue screen errors you will encounter, but they are some of the most common. In case you cannot determine your exact error code or the troubleshooting in those guides did not solve your problems, here are more general blue screen error solutions.
3. Check recent changes to the computer
Many times, you will begin to see errors on the blue screen after making a change to your system. Such changes can introduce problematic elements in a stable environment. Identifying this can help solve problems.
For example, if you have just installed a new printer, try unplugging it from your computer and see if the blue screen persists. If you recently ran a Windows update, go to Settings> Update and Security> Windows Update and click View update history .
On the next page with the list, click Uninstall updates at the top and delete the most recent update to see if that solves the problem.
The same goes for the software. If you only noticed that blue screens happen after installing a new application, try removing that application.
4. Check for Windows updates and drivers
While incorrect updates can present problems, Microsoft and other companies often issue updates to fix problems like these. Visit Settings> Update and security> Windows update and apply the pending updates, if they contain the solution.
It is also important to check your drivers, as they can often be a source of blue screens. Press Win + X (or right click on the Start button) to open the advanced user menu. Choose Device Manager to open that utility.
Here, check the yellow triangle icons, which indicate a problem with the controller. You should double check the devices that appear with this, as you may need to reinstall the driver or remove the device. You can right-click on an entry and choose Update Driver to check for updates, but this is not always reliable.
Instead, you should visit the website of your computer manufacturer and get the latest drivers from there. Follow our guide to update Windows driversfor help.
5. Performing a system restore
The System Restore function in Windows allows you to return your system to an earlier state. It is a useful tool for troubleshooting, as it is easy to use and allows you to see if your problem is based on software.
Type recovery in the Start menu and open the Recovery Control panel entry that appears. Here, click Open System Restore to start the tool. After clicking Next once, you will see a list of restore points to which you can return. Select one, then press Search for affected programs if you want to see what software will change.
Performing a system restore does not affect your files, but will uninstall any driver or software that you have installed since the restore point was performed. In addition, it will reinstall everything you have deleted since that time.
Confirm the restoration of your system, then you can start the process. This will take a few minutes, then it will return to your system as it was at that time. If you don't get blue screens after this, your problem is likely to be related to the software.
6. Scan for malware
Malware can damage Windows system files and cause a blue screen. You must perform an infection test to rule out something like this.
We recommend using the free version of Malwarebytes to run an analysis. This will search for all types of malicious software and remove it for you. If you find something, restart after cleaning and see if your blue screen errors disappear.
7. Test your computer hardware
If you have not discovered why you are receiving a blue screen of death, you should check the physical components of your computer. Sometimes, a faulty or similar RAM can result in a blue screen.
We have shown how to test your PC for hardware failuresbefore. Use those tools to test your system and you can plan to replace anything that is defective.
8. Run an SFC scan
Windows includes a command line tool called SFC (system file checker ). Run it looks for damaged files of the Windows system and tries to repair them. Doing so can solve the blue screen problem.
Again, press Win + X (or right-click on the Start button) to open the context menu for advanced users. Choose Command Prompt (Admin) or Windows PowerShell (Admin) then type the following:
sfc / scannow
Give it some time to run it and you can see the Results in a short time.
9. Booting in Safe Mode
Depending on the severity of your problem, you can perform all the troubleshooting steps above while working on Windows as usual. However, if you have a major problem, blue screen errors can prevent you from working normally. In that case, you must start in safe mode.
Safe mode allows you to load a basic Windows configuration with only the essentials you need to run. This prevents third-party applications from interfering with normal operation. If you can work in Safe Mode without touching a blue screen, it is an installed application or service that is causing the problem.
While in Safe mode, you can run a malware scan, use System Restore and, otherwise, troubleshoot as we have discussed.
10. Use advanced tools
For deeper troubleshooting, you can use tools that make the information that Windows dumps after it hangs easier to interpret . They are usually only for advanced users.
Follow our instructions on how to fix blue screen errors with WinDbg and BlueScreenViewto get help with some of these tools.
11. Reinstall Windows
If all else fails, you must reinstall Windows on your computer. At this point, you have ruled out the problems of drivers, hardware, malware and software, so there must be some deep underlying problem in your system.
Follow our guide to reset Windows 10to learn the best way to do this.
