The stop code on the BSOD screen is your roadmap to a fix. It might say something like Stop Code: MEMORY_MANAGEMENT or Stop Code: IRQL_NOT_LESS_OR_EQUAL. Jot it down or snap a photo with your phone. This code helps you pinpoint the issue when searching for solutions.
For example, CRITICAL_PROCESS_DIED often points to a failed system process, while SYSTEM_SERVICE_EXCEPTION might indicate a driver conflict. You can look up your stop code on Microsoft’s BSOD error code reference or forums like r/techsupport for community advice.
✅ 3. Update or Reinstall Problem Drivers
Drivers are the backbone of your PC’s communication system, and when they go wrong, BSODs follow. A bad graphics driver, for instance, might cause a VIDEO_TDR_FAILURE. Here’s how to check and fix drivers:
- Right-click Start and select Device Manager.
- Look for devices with a yellow warning triangle, which signals a problem.
- Right-click the device, choose Update Driver, and select Search automatically for drivers.
- For critical components like graphics cards, download the latest drivers directly from the manufacturer: NVIDIA, AMD, or Intel.
If a recent driver update caused the BSOD, go to Device Properties > Roll Back Driver to revert to the previous version. For example, if you updated your NVIDIA driver and started seeing SYSTEM_THREAD_EXCEPTION_NOT_HANDLED, rolling back might fix it.
✅ 4. Run SFC and DISM (System File Repair Tools)
Corrupted system files can wreak havoc, causing errors like CRITICAL_PROCESS_DIED. Windows has two powerful tools to fix this: System File Checker (SFC) and Deployment Image Servicing and Management (DISM). Here’s how to use them:
Open Command Prompt as Administrator (search for “cmd,” right-click, and select Run as Administrator). Then run:
sfc /scannowThis scans and repairs corrupted system files. If problems persist, run:
DISM /Online /Cleanup-Image /RestoreHealthDISM restores system health by downloading clean files from Microsoft’s servers. These tools are lifesavers for fixing file-related BSODs. Learn more at Microsoft’s SFC and DISM guide.
✅ 5. Check for Windows Updates
Sometimes, a BSOD is caused by a known bug that Microsoft has already patched. Keeping Windows updated can prevent or fix crashes. Here’s how:
- Go to Settings > Windows Update > Check for updates (Windows 11) or Settings > Update & Security > Windows Update (Windows 10).
- Install any pending updates, including optional driver updates.
- If a BSOD started after an update, roll it back via Settings > Windows Update > Update History > Uninstall Updates.
For Windows 11 users, updates are critical due to new hardware requirements like TPM 2.0. Check Microsoft’s Windows 11 support page for the latest updates.
✅ 6. Analyze Crash Logs
If the BSOD persists, it’s time to play detective. Tools like BlueScreenView or Windows’ built-in Event Viewer can reveal what’s causing the crash:
- Download BlueScreenView to see crash logs. It highlights the .sys file or driver responsible.
- Open Event Viewer (search for “eventvwr”) and go to Windows Logs > System. Look for errors or warnings around the time of the crash.
These tools can point to a specific driver or software causing the issue, like a faulty nvlddmkm.sys for NVIDIA graphics. For advanced users, WhoCrashed is another great tool for crash analysis.
