How To Fix Blue Screen On Windows 11

People are currently reading this guide.

Dealing with the dreaded Blue Screen of Death (BSOD) on your Windows 11 machine can be incredibly frustrating. It interrupts your work, can lead to data loss, and leaves you wondering what went wrong. But don't panic! While it can seem daunting, often you can troubleshoot and resolve the underlying issues yourself.

Let's dive right in! Have you recently installed any new hardware or software, or updated any drivers? This is often the culprit behind a sudden onset of blue screens. Keep that in mind as we go through the steps.

Here's a comprehensive guide to help you diagnose and fix the blue screen on your Windows 11 system:

Step 1: Gathering Information and Initial Actions

This initial stage is crucial for understanding what might be causing the problem.

1.1. Note Down the Error Message

When the blue screen appears, it usually displays a stop code (like STOP 0x0000007E) and a descriptive error message (like SYSTEM_THREAD_EXCEPTION_NOT_HANDLED). Carefully note down this information. This is your first clue! You can even take a picture with your phone. Search engines are your best friend here; searching for the specific stop code and error message can often lead you to articles or forum discussions with solutions specific to your issue.

1.2. Check Recent Changes

Think back to any changes you've made to your system recently. Did you:

Install new software or games?
Update any drivers (graphics, network, etc.)?
Connect new hardware devices?
Make any significant system configuration changes?

If the blue screen started appearing shortly after one of these actions, that's a strong indicator of the potential cause.

1.3. Perform a Restart

While it might seem obvious, sometimes a simple restart can resolve temporary glitches that might be causing the blue screen. After the restart, observe if the issue reappears. If it does, move on to the more in-depth troubleshooting steps.

1.4. Unplug External Peripherals

Disconnect all non-essential external devices like printers, external hard drives, USB hubs, and gaming controllers. Sometimes, a faulty peripheral can cause system instability. After disconnecting them, restart your computer and see if the blue screen persists. If it doesn't, reconnect your devices one by one to identify the problematic one.

Step 2: Booting into Safe Mode

Safe Mode starts Windows with a minimal set of drivers and startup programs. This can help you determine if a third-party application or driver is causing the blue screen.

2.1. Accessing Advanced Startup Options

If your PC can still boot (even if it eventually blue screens):

Press the Windows key + I to open the Settings app.
Click on System.
Scroll down and click on Recovery.
Under "Advanced startup," click on Restart now.

If your PC is stuck in a blue screen loop and you can't access Settings:

Hold down the power button for 5-10 seconds to force a shutdown.
Press the power button again to turn on your PC.
As soon as you see the manufacturer's logo, hold down the power button again for 5-10 seconds to force another shutdown.
Press the power button again to turn on your PC. This time, Windows should enter the Automatic Repair environment.
On the "Automatic Repair" screen, click on Advanced options.

2.2. Navigating to Safe Mode

In the "Choose an option" screen, click on Troubleshoot.
Click on Advanced options.
Click on Startup Settings.
Click on Restart.
After your PC restarts, you'll see a list of startup options. Press 4 or F4 to start in Safe Mode, 5 or F5 for Safe Mode with Networking, or 6 or F6 for Safe Mode with Command Prompt. Starting in Safe Mode is usually sufficient for initial troubleshooting.

2.3. Observing System Stability in Safe Mode

Once in Safe Mode, use your computer as you normally would (if possible). If the blue screens don't occur in Safe Mode, it strongly suggests that a third-party software, driver, or startup program is the culprit.

Step 3: Identifying and Resolving Software and Driver Issues

If Safe Mode resolves the blue screens, the next step is to pinpoint the problematic software or driver.

3.1. Uninstalling Recently Installed Software

If the blue screens started after installing a new program, try uninstalling it.

Press the Windows key + R, type appwiz.cpl, and press Enter. This opens the "Programs and Features" window.
Sort the list by "Installed On" date to easily find recently installed software.
Select the program you suspect might be the issue and click Uninstall.
Follow the on-screen instructions.
After uninstalling, restart your computer normally and see if the blue screens are gone.

3.2. Updating or Rolling Back Drivers

Outdated or faulty drivers, especially graphics drivers, are a common cause of BSODs.

Right-click on the Start button and select Device Manager.
Look for any devices with a yellow exclamation mark or a red "X" – these indicate problems.
Expand the categories (e.g., Display adapters, Network adapters).
Right-click on the device you want to update or roll back.
- To Update: Select Update driver, then Search automatically for updated driver software. Windows will try to find and install the latest driver.
- To Roll Back: If you recently updated a driver and the problems started, select Properties, go to the Driver tab, and if the "Roll Back Driver" button is available (not grayed out), click it. This will revert to the previous driver version.
After updating or rolling back drivers, restart your computer.

3.3. Running System File Checker (SFC)

The System File Checker is a built-in Windows tool that scans for and restores corrupted system files.

Press the Windows key + S, type cmd, and right-click on Command Prompt. Select Run as administrator.

In the Command Prompt window, type sfc /scannow and press Enter.

Wait for the scan to complete. This process can take some time.
If SFC finds and repairs any errors, restart your computer.

3.4. Using the Deployment Image Servicing and Management (DISM) Tool

DISM is another command-line tool that can be used to repair the Windows image.

Open Command Prompt as administrator (as described in the SFC step).

Type the following command and press Enter:

DISM /Online /Cleanup-Image /RestoreHealth

Wait for the command to complete. This can also take some time.
After the DISM process is finished, restart your computer.

Step 4: Checking Hardware Issues

If software and driver troubleshooting doesn't resolve the blue screens, the problem might be with your hardware.

4.1. Testing Your RAM (Memory)

Faulty RAM can lead to various system issues, including BSODs. Windows has a built-in Memory Diagnostic tool.

Press the Windows key + S, type memory diagnostic, and select Windows Memory Diagnostic.
You'll be presented with two options: "Restart now and check for problems (recommended)" or "Check for problems the next time I start my computer." Choose the first option.
Your computer will restart and perform a memory test. Let it complete the process.
After the test, your computer will restart again. The results of the memory test will usually be displayed as a notification. You can also find the results in the Event Viewer (search for "Memory-Diagnostic").

4.2. Checking Your Hard Drive or SSD

Problems with your storage device can also cause blue screens. You can use the chkdsk command to check for errors.

Open Command Prompt as administrator.
Type chkdsk /f /r and press Enter.
You'll be asked if you want to schedule the check for the next system restart. Type y and press Enter.
Restart your computer. chkdsk will run before Windows starts and attempt to fix any errors it finds.

Warning: Using /r parameter will attempt to recover readable information from bad sectors. This process can be time-consuming and might lead to data loss in severely damaged drives. Back up your important data before running this command.

4.3. Monitoring System Temperatures

Overheating components, especially the CPU and GPU, can cause system instability and blue screens. You can use monitoring software like HWMonitor or Core Temp to check your system temperatures. Ensure they are within the normal operating ranges for your hardware. If temperatures are consistently high, you might need to clean the dust from your computer's cooling system or consider reapplying thermal paste.

4.4. Examining Newly Installed Hardware

If the blue screens started after installing new hardware, ensure it's properly seated, compatible with your system, and that you have the correct drivers installed. Try removing the new hardware to see if the issue resolves.

Step 5: Advanced Troubleshooting and Recovery Options

If the previous steps haven't fixed the blue screen, you might need to explore more advanced options.

5.1. Performing a System Restore

System Restore allows you to revert your computer's system files and settings to a previous point in time, called a restore point. This can be helpful if the blue screens started after a recent system change.

Press the Windows key + S, type restore point, and select Create a restore point.
In the "System Properties" window, click on the System Restore... button.
Click Next.
If you see a "Show more restore points" option, check it.
Select a restore point that was created before the blue screens started occurring.
Click Scan for affected programs to see which programs and drivers will be affected by the restore.
Click Next and then Finish to start the system restore process.

Note: System Restore will not affect your personal files, but it will uninstall programs and drivers installed after the selected restore point.

5.2. Resetting Your PC

Resetting your PC allows you to reinstall Windows. You can choose to keep your personal files or remove everything.

Open the Settings app (Windows key + I).
Click on System.
Click on Recovery.
Under "Reset this PC," click on Reset PC.
Follow the on-screen instructions. You'll have options to "Keep my files" or "Remove everything."

Warning: If you choose "Remove everything," make sure you have backed up any important data.

5.3. Performing a Clean Installation of Windows 11

A clean installation involves completely erasing your hard drive and installing a fresh copy of Windows 11. This is a more drastic step but can resolve persistent issues. You'll need a bootable USB drive with Windows 11 installation files.

Warning: This will erase all data on your hard drive. Ensure you have a complete backup before proceeding.
