The Blue Screen of Death (BSOD) is a critical error that
forces your computer to restart. It usually indicates a serious problem with
hardware, drivers, or system software. Here’s a step-by-step guide to solving
BSOD issues:

1. Note the Error Code

• When
  a BSOD occurs, an error code or message (e.g., IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT_IN_NONPAGED_AREA)
  appears.
• Write
  down the error code or take a photo for reference.

2. Restart in Safe Mode

• Safe
  Mode runs your computer with minimal drivers and services, which can help
  identify the issue.

Windows 10/11:

1. Restart
   your computer and hold the Shift key while selecting Restart.
2. Navigate
   to Troubleshoot > Advanced Options > Startup
   Settings > Restart.
3. Press
   4 or F4 to start in Safe Mode.

Windows 7:

1. Restart
   your computer and press F8 repeatedly before the Windows logo
   appears.
2. Select
   Safe Mode from the menu.

3. Check for Driver Issues

• Outdated
  or incompatible drivers often cause BSODs.

Update Drivers:

1. Open
   Device Manager (Windows + X > **Device Manager`).
2. Look
   for devices with a yellow exclamation mark.
3. Right-click
   the device and select Update Driver > Search automatically
   for updated driver software.

Roll Back Drivers:

• If
  the issue started after a driver update, roll back to the previous
  version:

   to Settings > Update & Security > Windows
   Update.

   Check for Updates and install any available updates.

5. Scan for Malware

  can corrupt files or interfere with critical processes, causing BSODs.

1. Run
   a full system scan using antivirus software or Windows Security.

   tools like Malwarebytes for additional scanning.
