Fix Windows Blue Screen (BSOD) - Step-by-Step Guide

Your PC keeps crashing to a blue screen, and you need to get back to work without losing your data or sanity. Most of the time, this happens because a driver conflict or a corrupted system file is stopping Windows from running properly. Follow these steps in order to isolate exactly what is breaking your system.

Identify the Cause

Before running repairs, check your Event Viewer for the specific Stop Code to narrow down if the issue is hardware or software related. If you see 'driver' in the error name, prioritize updating or rolling back your device drivers first.

Prerequisites

You will need administrative access to your Windows account to run these diagnostic commands. Ensure you have time to let the disk and memory scans complete, as they can take up to 30 minutes.

Steps

1. 01
   Right-click the Start button and select Device Manager to look for any devices with yellow warning triangles.
2. 02
   If a device shows a warning, right-click it, select Update driver, and choose Search automatically for drivers.
3. 03
   If a driver was recently updated, right-click the device, select Properties, go to the Driver tab, and click Roll Back Driver.
4. 04
   Open the Command Prompt as administrator, type sfc /scannow, and press Enter to repair corrupted system files.
5. 05
   If system file errors remain, type DISM /Online /Cleanup-Image /RestoreHealth in the same window and press Enter.
6. 06
   To check your drive for bad sectors, type chkdsk C: /f /r and press Enter, then type Y to schedule the scan for your next restart.
7. 07
   Restart your PC and let the disk check run to completion without interruption.
8. 08
   For memory issues, open the Run dialog with Win+R, type mdsched.exe, and select Restart now to check for problems.
