If you have ever spent any time using a computer, you may be familiar with the term ‘Blue Screen of Death’ (BSOD) and you might have even seen a few of them. ‘Blue Screen of Death’ is a light-hearted term for a ‘stop code’, which gives information detailing why a computer crashed.

A Microsoft Windows blue screen, also known as a blue screen of death.
Recognise this?

The Blue Screen first appeared in Windows NT 3.1 (released in 1993) and they stayed very similar up until the release of Windows 10 (2015) when they revamped it with the sad face image, shown in the image above.

This newer version of the BSOD is more user friendly and doesn’t contain as much information, instead of giving a code it gives us the English translation for it, in the example “CRITICAL_PROCESS_DIED” and a QR code that when scanned takes you to a webpage and explains a little bit about debugging.

The image below shows the older version of a Blue Screen of Death from Windows 7. Note how it provides more information.

We can see that the stop code is “0x0000001E” and then the parameters for the code are “0x8000003, 0x8008CB62” etc. The last section at the bottom lists NTOSKRNL.EXE which is a fundamental part of a Windows operating system that links software to hardware.

What causes a BSOD?

  • A BSOD can be caused by a whole range of errors, but they are usually caused by a faulty driver or faulty hardware. If you have recently changed some hardware and a BSOD starts to occur it’s worth swapping the hardware out to see if they stop. If they do, then you either haven’t updated the drivers on the system to match the new hardware, or the hardware may be faulty.
  • If you have recently updated some drivers or installed some software, then this would be the most likely cause of the BSOD. The first step in troubleshooting a Blue screen is asking yourself “What’s changed?”.

If you find yourself in a position where you encounter a “Blue Screen of Death” please note down the details from it or take a photo of it and restart your computer. If it happens again then it’s time to troubleshoot. You can find a list of bug check codes from Microsoft here that will be of help you to understand what your specific bug check is for.
