Blue Screen of Death (BSOD): What It Means and How to Fix It

A Blue Screen of Death means Windows hit an error it could not recover from and restarted to protect your data. The stop code on the screen is your biggest clue.

Common causes

Faulty or unstable drivers, failing RAM, disk corruption, overheating, or recently installed hardware/software are the usual culprits.

1. Note the stop code

Write down the error (e.g., IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT_IN_NONPAGED_AREA). It narrows the cause significantly.

2. Undo recent changes

If it started after a new driver, update, or device, roll it back or remove it.

3. Test memory and disk

Run Windows Memory Diagnostic and check disk health (SMART). Bad RAM or a failing drive cause frequent BSODs.

4. Update drivers and Windows

Outdated graphics and storage drivers are the most common repeat offenders.
