Why Did My Computer Show A Blue Screen?

Several end users wonder “Why did my computer show a blue screen?” This is what is famously known as blue screen of death (BSoD), blue screen errors, or Stop errors. Before you start troubleshooting this problem, you must first determine what type of BSoD you’re dealing with since there are several reasons why you may be getting this error.

This type of error in Windows is usually hardware or driver related. The blue screen of death is typically in hexadecimal format, which uniquely classifies a specific error. In most cases, you won’t be able to read the text on your monitor when this happens since your computer may suddenly reboot. So, if this happens you can perform the following steps in order to check what BSoD error you have.

1. If you’re using Windows 7, click the Start icon then right click on My Computer then select Properties.

2. On the System Properties window, select Advanced System Settings then click on Settings under Startup and Recovery.

3. Make sure to deselect Automatically Restart under System Failure then click Ok.



If your computer doesn’t allow you to perform these steps, then you need boot into Safe Mode. Follow these steps if you’re using Windows operating system.

1. Restart your PC.

2. While your computer is restarting and before Windows launches, press F8.

3. Select the option for Safe Mode then press Enter.

4. If you are using a dual boot system, select the installation  you need to access then press Enter.


In identifying BSoD or Stop errors, take a look at those that are in capital letters and underscores instead of spaces. You may also look at the top portion that looks something like STOP:0x000000XX. Make sure to jot down these error codes on a piece of paper as your reference. Most of the time, with this information on hand, you will finally be able to answer the question “Why did my computer show a blue screen?”

Also, here are some general troubleshooting steps to consider when you’re getting the blue screen of death (BSoD). Any of these steps usually does the trick.

1. It’s also a good idea to ask yourself what was the most recent change you’ve done to your computer because this could be the reason why you’re getting the blue screen of death. Depending on the type of error you can perform Startup using Last Known Good Configuration, a System Restore, or roll back your drivers to prior version.


How to Start Windows using Last Known Good Configuration


a) Press F8 during Windows Splash screen.

b) On the Advanced Boot Options screen, select Last Known Good Configuration by using the arrow keys on your keyboard.

c) Wait patiently for Windows to load then login to your account. If your computer still keeps rebooting or if you’re still getting a Stop error then the next best step is doing a System Restore.


How to Perform a System Restore on Windows:


The System Restore tool in Windows is very useful especially when you’re dealing with problems caused by the registry, drivers or DLL files.


a) Click Start orb icon >> All Programs >> Accessories >> Systems Tools >> System Restore.

b) Select Next under Restore system files and settings window, and then select a specific restore point. You may click on Show more restore points check box to view previous restore points then click Next.


c) Select Finish under Confirm your restore point to start the System Restore process. At this point, make sure to save all your files since Windows will shut down your computer as part of the process.

d) Choose Yes, once a dialog box that states “Once started, System Restore cannot be interrupted. Do you want to continue?” appears.

e) The process will take a few minutes and you will see a message that states “Please wait while your Windows files and settings are being restored” letting you know that the system restore is taking place.

f) Click Close once you get the message System Restore completed successfully. Check to see if you’re still having the blue screen error. If yes, then proceed to rolling back your device drivers to its prior version.


How to Use the Driver Roll back tool in Windows:


This tool allows you to roll back your driver settings back to the version when it was last updated. There are instances when updating the driver settings would create problems with your computer and cause Stop errors.


a) Click on Start >> Control Panel >> Device Manager. For Windows 7,  you may also type or enter Device Manager on the Search box.

b) In the Device Manager window, highlight the driver and specific hardware you wish to roll back then right click and select Properties >> Driver tab >> Roll Back Driver. If the Roll Back Driver option is greyed out, this means that there is no previous driver to roll back to.




c) Select Yes when you get the question “Are you sure you would like to roll back to the previously installed driver software?”

d) Click Close then select Yes when you get “Your hardware settings have changed. You must restart your computer for these changes to take effect. Do you want to restart your computer now?” You may not be asked to restart your computer at all since this depends on the type of hardware you’re rolling back. Keep in mind that this tool only allows you to roll back once since Windows only keeps a copy of the version before your driver was updated.


2. Even after undoing the changes or updates done on your computer and you’re still asking the question “Why did my computer show a blue screen” then you might consider double checking the  min. amount of free space on your partition since data corruption may occur if there’s not enough space on your main partition.


3. Viruses like MBR or Master Boot Record or Boot Sector may also cause blue screen of death errors. So, ask yourself if you’re anti-virus software is still up-to-date since this may just be the cause of your problems.
