What is a blue screen of death?

The blue screen of death - or BSOD - is caused when a Microsoft Windows machine encounters a critical error that it cannot fix; this is usually caused by low-level software or faulty hardware.

What Causes the Blue Screen of Death?

Blue screens are generally caused by problems with your computer’s hardware or issues with its hardware driver software. Sometimes, they can be caused by issues with low-level software running in the Windows kernel. Regular apps usually won’t be able to cause blue screens. If an app crashes, it will do so without taking the operating system out with it. A blue screen occurs when Windows encounters a “STOP Error.” This critical failure causes Windows to crash and stop working. The only thing Windows can do at that point is restart the PC. This can lead to data loss, as programs don’t have a chance to save their open data. When a blue screen occurs, Windows automatically creates a “minidump” file that contains information about the crash and saves it to your disk. You can view information about these minidumps to help identify the cause of the blue screen.

What does a Blue Screen of Death Look Like?

In Windows 7 and before, the Blue Screen of Death was a very convoluted page, with lots of technical words.


In Windows 8 and 10, the Blue Screen of Death is much simpler.

What can you do if you start experiencing BSOD's?

If you have trouble locating good advice for solving your problem, don’t worry. BSODs can have a variety of root causes. Here are some additional tips that might help you deal with many blue screens:

• Use System Restore: If your system just started blue screening, it may be a software issue. You should use System Restore to try to fix the problem. If this works, then you know it is a software issue.
• Scan for Malware: Sometimes, malware can cause system instability. You should regularly scan your computer for malware to make sure that the malicious software isn't crashing your computer
• Install Updated Drivers: An old driver, a falsely installed driver, and a buggy driver could be a cause for BSODs. Make sure you have the latest drivers and install them correctly
• Boot into Safe Mode: If your computer blue-screens every time you turn it on, try booting it into safe mode. When you boot it into safe mode, windows only uses the essential drivers and from there, you can further troubleshoot your problem
• Check for Hardware Problems: Another cause for BSODs is faulty hardware. Make sure you test your computer's memories for errors and checking your computer's temperature to make sure it isn't overheating. Additionally, you could hire a pro to check other parts that may have gone bad. 
• Reinstall Windows: Your very last option could be to do a clean install of windows. This will completely remove your existing software and replace it with a new one. If your computer continues to blue screen after that, then it is a hardware problem
