How to Fix the Blue Screen of Death (BSOD) on Windows 11

See the Blue Screen of Death on Windows 11? Follow these 8 proven fixes to stop BSOD crashes fast — no reinstall needed.

Introduction

One second your PC is running fine; the next it crashes to a blue screen with a sad emoji and the message “Your PC ran into a problem and needs to restart.” That’s the Blue Screen of Death (BSOD) — and it’s one of the most alarming things a Windows user can experience.

The BSOD on Windows 11 is Windows’ emergency shutdown. It kicks in when the system hits an error so serious it can’t keep running safely. The most common culprits are faulty or outdated drivers, corrupted system files, failing RAM, and overheating hardware.

The good news: most BSODs are fixable without reinstalling Windows. Work through the steps below in order and you’ll likely stop the crashes for good.

Quick Answer

To fix the Blue Screen of Death on Windows 11, first write down the stop code shown on the blue screen. Then run Windows Update, update or roll back drivers in Device Manager, and run sfc /scannow in an elevated Command Prompt to repair corrupted files. These three steps resolve the majority of BSODs without a Windows reinstall.

What Causes the Blue Screen of Death on Windows 11?

The BSOD is a safety mechanism, not just a random glitch. Windows halts everything to prevent deeper damage when it detects a critical failure it can’t recover from. Common causes include:

  • Outdated or corrupted drivers — the #1 cause, especially after a Windows update or new hardware install
  • Corrupted system files — core Windows files that have become damaged or incomplete
  • Faulty RAM — a bad memory stick causes unpredictable, hard-to-diagnose crashes
  • Overheating — your CPU or GPU running too hot triggers a forced shutdown to protect hardware
  • Malware — malicious software that corrupts critical system files
  • Incompatible software — a recently installed app or update that conflicts with Windows internals

How to Fix the BSOD on Windows 11: 8 Steps

Step 1: Note the Stop Code

When the blue screen appears, find the stop code near the bottom of the screen — it looks like CRITICAL_PROCESS_DIED, DRIVER_IRQL_NOT_LESS_OR_EQUAL, MEMORY_MANAGEMENT, or similar. Write it down before your PC restarts. This single piece of information points you directly at the cause.

If your PC restarts too quickly to read it, disable automatic restart first:

  1. Press Windows + I to open Settings.
  2. Go to System > About, then click Advanced system settings on the right.
  3. Under Startup and Recovery, click Settings.
  4. Uncheck Automatically restart and click OK.

Now the blue screen will stay visible long enough to read the stop code.

Step 2: Run Windows Update

Microsoft regularly releases patches that fix known crash bugs and driver conflicts. Running all available updates is the easiest and safest first step.

  1. Press Windows + I to open Settings.
  2. Click Windows Update in the left sidebar.
  3. Click Check for updates and install everything listed.
  4. Restart your PC when prompted.

Pro tip: Also open Advanced options > Optional updates — driver updates often appear there separately and can resolve a BSOD that the main update list misses. If Windows Update itself won’t run, see our guide on how to fix Windows Update not working on Windows 11.

Step 3: Update or Roll Back Your Drivers

Faulty drivers cause the majority of BSODs. If crashes started right after installing new hardware or running a Windows update, go here first.

To update a driver:

  1. Right-click the Start button and select Device Manager.
  2. Expand the relevant category — for example, Display adapters for a GPU-related BSOD, or Network adapters for network driver issues.
  3. Right-click the device and choose Update driver > Search automatically for drivers.
  4. Restart your PC after the update completes.

To roll back a driver (if BSODs started immediately after a driver update):

  1. In Device Manager, right-click the device and select Properties.
  2. Click the Driver tab, then click Roll Back Driver if the button is available.

Troubleshooting tip: If Device Manager reports the driver is already up to date but crashes continue, visit the manufacturer’s website directly — Intel, NVIDIA, AMD, or Realtek — and download the latest driver from there. Windows sometimes lags weeks behind the manufacturer’s own releases.

Step 4: Repair Corrupted System Files with SFC and DISM

Corrupted Windows files are a common BSOD trigger. Two built-in command-line tools fix this — run them in order for best results.

  1. Click Start, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type sfc /scannow and press Enter. The scan takes 10–15 minutes — let it finish completely.
  3. Once done, type the command below and press Enter:
    DISM /Online /Cleanup-Image /RestoreHealth
  4. Wait for DISM to complete, then restart your PC.

SFC (System File Checker) finds and repairs damaged files. DISM repairs the underlying Windows image that SFC uses as its reference. Always run both — one without the other leaves the job half done.

Troubleshooting tip: If SFC reports errors it couldn’t fix, run DISM first, then run SFC again. DISM needs to repair the image before SFC can use it successfully.

Step 5: Check for Overheating

If your PC blue screens during demanding tasks — gaming, video editing, or after running for a while — heat may be the culprit. Download a free tool like HWMonitor or Core Temp to check your CPU and GPU temperatures while the PC is under load.

  • Normal CPU temps under load: up to ~85°C. Sustained temps above 95°C are a warning sign.
  • If overheating: clean dust from vents and fans, make sure your PC has room to breathe around it, and verify all fans are spinning correctly.
  • On laptops, never use the machine on a soft surface like a bed or sofa — it blocks the vents and can raise temps by 15–20°C in minutes.

Random BSODs combined with freezing or stuttering can also point to software conflicts — see our guide on fixing Windows 11 freezing for related fixes that may also apply.

Step 6: Test Your RAM

Faulty memory sticks trigger stop codes like MEMORY_MANAGEMENT and PAGE_FAULT_IN_NONPAGED_AREA. Windows has a built-in RAM test you can run for free:

  1. Press Windows + R, type mdsched.exe, and press Enter.
  2. Choose Restart now and check for problems.
  3. Your PC will restart and run the memory diagnostic — this takes several minutes.
  4. After your PC restarts, check results in Event Viewer: press Windows + R, type eventvwr.msc, go to Windows Logs > Application, and look for the MemoryDiagnostics-Results entry.

If the test reports errors, your RAM likely needs replacing. If you have two sticks installed, try them one at a time to identify which one is faulty.

Step 7: Run a Full Malware Scan

Some malware corrupts core system files and causes repeated BSODs that look like hardware problems. Run a full scan with the built-in Windows Security tool:

  1. Press Windows + I, go to Privacy & Security > Windows Security.
  2. Click Virus & threat protection, then Scan options.
  3. Select Full scan and click Scan now.
  4. Let the scan finish completely — don’t interrupt it partway through.

Step 8: Use System Restore

If your BSODs started recently — after a new program install, a driver change, or a system update — System Restore can roll Windows back to a point before the problem began, without touching your personal files.

  1. Press Windows + R, type rstrui.exe, and press Enter.
  2. Click Next and choose a restore point dated before the crashes started.
  3. Follow the prompts and let your PC restart through the process — don’t power it off mid-way.

System Restore only reverses system settings and installed programs. Your documents, photos, and personal files are not affected.

Common Mistakes to Avoid

  1. Ignoring the stop code. The stop code is your most valuable diagnostic clue. Skipping it means troubleshooting blind. Always write it down before anything else.
  2. Reinstalling Windows immediately. This is rarely necessary. Work through Steps 2–8 first — the vast majority of BSODs are fixable without a full reinstall and without losing your files.
  3. Running SFC without administrator rights. If you open Command Prompt normally (not as administrator), SFC will fail silently and report success without actually fixing anything. Always right-click and choose “Run as administrator.”
  4. Running only SFC and skipping DISM. If the Windows image itself is corrupted, SFC can’t use it to repair files. Always follow SFC with a DISM scan — they’re designed to work together.
  5. Assuming the newest driver is always safe. Occasionally, a fresh driver release introduces new bugs. If rolling back to an older version stops the crashes, stay on it until the manufacturer releases a stable update.

Frequently Asked Questions

Is the Blue Screen of Death serious?
A single BSOD isn’t always critical — it can result from a one-time glitch. Repeated BSODs signal a real underlying problem (faulty driver, bad RAM, or corrupted files) that needs to be fixed promptly.

Will I lose my files after a BSOD?
Files already saved to your drive are almost always safe. Only unsaved work at the exact moment of the crash is lost. Permanent data loss from a BSOD is rare unless your hard drive itself is failing.

What does “Your PC ran into a problem and needs to restart” mean?
This is Windows 11’s standard blue screen message. The critical information is the stop code shown below that line — for example, CRITICAL_PROCESS_DIED — which identifies the specific type of failure that occurred.

Do I need to reinstall Windows to fix a BSOD?
Almost never. Updating drivers, running SFC and DISM, and checking your hardware resolves the vast majority of BSODs. A clean reinstall is a last resort only when every other fix has failed.

Why does my PC blue screen only during games?
Gaming pushes your GPU and CPU to their limits. Blue screens that only happen in games usually point to an outdated graphics driver, a GPU running too hot, or a power supply that can’t deliver enough power under load. Start by updating your GPU driver.

How do I find BSOD crash logs on Windows 11?
Open Event Viewer by pressing Windows + R and typing eventvwr.msc. Navigate to Windows Logs > System and look for events marked Critical or Error around the time of the crash — they often name the exact driver or component that failed.

Can a BSOD damage my PC?
The BSOD itself is a protective mechanism and doesn’t cause damage. However, if the underlying cause is overheating or failing hardware, that root problem can cause lasting damage over time. Fix the cause as soon as possible.

Conclusion

The Blue Screen of Death is alarming, but it’s almost always fixable without reinstalling Windows. Start by noting the stop code, run Windows Update, update or roll back your drivers, and repair system files with SFC and DISM. If crashes persist, check for overheating and test your RAM. Work through the steps in order and you’ll likely put a stop to the crashes for good.

Windows 11 Keeps Freezing? Here’s How to Fix It (8 Proven Fixes)

Windows 11 keeps freezing randomly? Use these 8 proven fixes — update drivers, run SFC, free up disk space, check for overheating, and more. No tech skills needed.

Introduction

Your screen goes still. The mouse cursor stops moving. Nothing clicks. Windows 11 keeps freezing at the worst possible moment — and it’s one of the most frustrating tech problems you can face.

The freeze can last a few seconds or force a hard restart. It might happen once a day or every hour. Either way, there’s a reason: too little memory, a corrupt driver, a rogue startup program, or even a bad Windows update.

The good news? Most freezes have a fixable cause, and you can diagnose and solve the problem using free, built-in Windows tools — no technical background required.

Quick Answer

To fix Windows 11 freezing, restart your PC and install all pending Windows updates. Then open Task Manager (Ctrl + Shift + Esc) to check for high CPU or RAM usage. Run sfc /scannow in an elevated Command Prompt to repair corrupted system files. If freezing continues, update your drivers and disable non-essential startup programs.

Why Does Windows 11 Keep Freezing?

Before diving into fixes, it helps to know what’s usually to blame:

  • Outdated or corrupt drivers — especially display, chipset, and storage drivers
  • Insufficient RAM — too many apps competing for limited memory
  • Overheating — the CPU or GPU slows itself down to cool off, causing hitches
  • Corrupted system files — Windows components damaged by a bad update or improper shutdown
  • Too many startup programs — apps loading at boot eat resources before you do anything
  • Low disk space — Windows needs free space for virtual memory (page file)
  • Faulty Windows Update — rare, but a bad patch can trigger random freezes

Fix 1: Restart and Install Windows Updates

A full restart clears memory leaks and queued processes that cause freezing. After restarting:

  1. Press Windows key + I to open Settings.
  2. Go to Windows Update.
  3. Click Check for updates and install everything available.
  4. Restart again when prompted.

Windows updates often include stability patches and driver fixes that directly address freeze issues.

Pro tip: If Windows Update itself isn’t working, see our guide on How to Fix Windows Update Not Working on Windows 11.

Troubleshooting tip: If your PC freezes during an update, hold the power button to force a shutdown, then restart normally. Windows usually recovers automatically on the next boot.

Fix 2: Check RAM and CPU Usage in Task Manager

A frozen PC is often an overloaded PC. Task Manager shows you exactly what’s eating your resources.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click the Processes tab.
  3. Click the CPU column header to sort by highest usage, then do the same for Memory.
  4. If one app is using 80–100% of CPU or hogging memory, right-click it and choose End task.

If you see high usage with nothing obvious running, you may have too little RAM for your workload — or a background process like antivirus is scanning at the wrong time.

Fix 3: Update (or Roll Back) Your Drivers

Outdated or buggy drivers — particularly display and storage drivers — are a leading cause of random freezes.

To update a driver:

  1. Right-click the Start button and choose Device Manager.
  2. Expand the category you want to check (e.g., Display adapters, Disk drives).
  3. Right-click the device and choose Update driver > Search automatically for drivers.

To roll back a driver (if freezing started after a recent update):

  1. In Device Manager, right-click the device and choose Properties.
  2. Click the Driver tab.
  3. If Roll Back Driver is available, click it and follow the prompts.

Troubleshooting tip: If the automatic driver search finds nothing new, visit the manufacturer’s website (NVIDIA, AMD, Intel, or your laptop maker) to download the latest version directly.

Fix 4: Disable Startup Programs

Dozens of apps can silently load at startup, eating RAM before you even open a browser. Trimming the list often stops freezes immediately.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click the Startup apps tab.
  3. Look at the Startup impact column.
  4. Right-click any “High” impact app you don’t need at startup and choose Disable.
  5. Restart your PC.

Don’t disable your antivirus or any hardware utility. Everything else — Spotify, Discord, OneDrive (unless you actively need it at boot) — is fair game.

Fix 5: Run System File Checker (SFC)

Corrupted Windows system files cause unpredictable behavior, including random freezes. The built-in SFC tool scans and repairs them automatically.

  1. Click the Search bar, type cmd, right-click Command Prompt, and choose Run as administrator.
  2. Type the following command and press Enter:
sfc /scannow
  1. Wait for the scan to finish — it takes 10–15 minutes.
  2. If SFC reports it fixed files, restart your PC.

If SFC reports it couldn’t repair everything, run this command next:

DISM /Online /Cleanup-Image /RestoreHealth

Then run sfc /scannow a second time.

Pro tip: Run SFC at least once a month if your PC tends to be unstable.

Fix 6: Free Up Disk Space

Windows 11 uses free disk space as virtual memory. If your drive is nearly full, the system has nowhere to expand memory — and freezes. Keep at least 10–15% of your drive free at all times.

  1. Press Windows key + I, then go to System > Storage.
  2. Click Temporary files and remove what you don’t need.
  3. Turn on the Storage Sense toggle to automate future cleanups.

Fix 7: Check for Overheating

When a CPU or GPU gets too hot, it slows itself down to prevent damage — and that throttling looks exactly like a freeze. Common signs: freezes during gaming or video editing, fans running loud just before a freeze, a laptop that’s hot to the touch.

  1. Download a free temperature monitor: HWMonitor or Core Temp are both reputable and free.
  2. Watch your CPU temperature while working. Anything consistently above 90 °C under load is a problem.
  3. If temps are high: clean dust from vents, make sure airflow around your PC is clear, or (for desktops) consider refreshing the thermal paste.

Troubleshooting tip: On laptops, a cooling pad or simply elevating the rear of the laptop a few centimetres can drop temperatures noticeably.

Fix 8: Perform a Clean Boot

A clean boot starts Windows with only essential Microsoft services and no third-party apps. If the freezing stops in a clean boot, a background app is the culprit.

  1. Press Windows key + R, type msconfig, and press Enter.
  2. On the Services tab, check Hide all Microsoft services, then click Disable all.
  3. Click the Startup tab, choose Open Task Manager, and disable all startup items.
  4. Click OK, then restart your PC.
  5. Test for freezing. If it’s gone, re-enable services in small batches to identify the one causing the problem.

Common Mistakes to Avoid

  • Logging off instead of restarting. Signing out and back in is not the same as a restart. A full restart clears memory and applies pending updates — always do this first.
  • Ignoring Windows Update. A single missed stability patch can cause months of freezing. Keep updates current.
  • Disabling antivirus to “speed things up.” Your antivirus may be scheduling scans at peak times, which looks like a freeze. Change its scan schedule instead of disabling protection.
  • Running SFC without admin rights. SFC silently fails without administrator privileges. Always right-click Command Prompt and choose Run as administrator.
  • Letting the drive fill to the brim. A drive at 95–100% capacity causes regular freezes. Keep at least 10–15% free space.
  • Jumping straight to a Windows reinstall. Most freezes are fixable without reinstalling. Work through Fixes 1–8 first — a reset is a last resort.
  • Forgetting to check driver rollbacks. If freezing started after a specific date, check what updated that day. Rolling back the driver often resolves it in minutes.

Frequently Asked Questions

Why does Windows 11 freeze randomly with no warning?

Random freezes usually point to driver conflicts, insufficient RAM, or an overheating CPU. Run Task Manager during normal use to watch for resource spikes, and check CPU temperatures with a free tool like Core Temp or HWMonitor.

Can a virus cause Windows 11 to keep freezing?

Yes. Malware running in the background can consume CPU and RAM, causing freezes. Open Windows Security, go to Virus & threat protection, and run a Full scan to rule this out.

Does more RAM fix Windows 11 freezing?

Sometimes. If Task Manager consistently shows your RAM at 90%+ during normal use, adding more RAM will help. Most Windows 11 PCs benefit from 16 GB for everyday multitasking.

Will resetting Windows 11 fix the freezing?

It usually does, but it’s a last resort. Try all 8 fixes in this guide first. If nothing works, go to Settings > System > Recovery > Reset this PC and choose “Keep my files.”

How do I know if my hard drive is causing the freezes?

Use the free tool CrystalDiskInfo to check your drive’s health. If it shows “Caution” or “Bad,” your drive is failing and needs replacing — back up your files immediately.

Is Windows 11 more prone to freezing than Windows 10?

Not inherently. Most freezes on Windows 11 come from outdated drivers that haven’t been updated for Windows 11 compatibility. Keeping drivers current resolves the majority of cases.

What if Windows 11 freezes at startup, before I can do anything?

Boot into Safe Mode by holding Shift while clicking Restart, then go to Troubleshoot > Advanced options > Startup Settings > Restart, and press 4. In Safe Mode, run SFC and check Device Manager for any device marked with a yellow warning icon.

Conclusion

A Windows 11 PC that keeps freezing is aggravating — but it’s almost always fixable without paying a repair shop. Start with a restart and Windows Update, use Task Manager to spot resource hogs, run SFC to repair system files, and check for overheating. Work through the eight fixes in order and you’ll find and eliminate the cause.
