“SYSTEM THREAD EXCEPTION NOT HANDLED” or “0X0000007E” both are the same BSOD (Blue screen of death) errors and this error mainly indicates that there is a system thread generated with an exception that the error handler was not able to catch in your Windows Operating System.

In a normal language, if you’re seeing this error continuously on your computer’s screen that means your computer system is might get some kind of OS or a hardware related problem. I know it feels really annoying when you get this error in the middle of your work or may be on your system’s startup, but hang on for a while because I will definitely going to help you out for that.

The bad thing which hates about this error is that your computer’s OS doesn’t know which part or software of your PC is creating this problem and that’s the reason why you need to troubleshoot this BSOD according to the condition what you are currently facing.

Normally this error caused by different types of reasons what I’m all listed below and because of those, now you’ll need to try some different solution in order to fix your computer.

Here’s The List of Causes for “System Thread Exception Not Handled” BSOD:

  • Boot Volume Problem (Hard disk problem)
  • Drivers Corruption
  • Windows Problem
  • BIOS Corruption


Now as you know, there are some different types of solutions you’ll need to perform on your computer system to fix this problem. So, just stick with this tutorial and follow every single step which I’m all suggested below in this article.

So, I categorize the solutions into three different parts according to the different conditions –

  1. On Operating System Startup – Yes, most of the times this error occurred right after when you start your Computer’s Operating System, even whatever version of Windows you are using in it, and after that, it will restart your computer by showing you the blue screen background with this “SYSTEM THREAD EXCEPTION NOT HANDLED” error code on it.
  2. While Working – Sometimes it’s also possible that this error occurred while when you’re working on some software or playing some game on your PC.
  3. While Operating System Installation – Often this error also showed up while installing Windows OS or may be some other type of OS in our PC.

In this article, I’m only gonna cover first two conditions properly because if you having the third one “getting error While Windows Installation” then it’s your hard disk problem or maybe that version of Windows isn’t compatible with your computer. To confirm about that, you can use some different hard disk drive or some different Operating System disc on your computer and then again try to reinstall the OS.

Note: Yes, you can skip the whole Condition No. 1 steps and solution and move to next one, in case if you are having the second one on your side.

Condition No#1 – Fixing Startup Error

Getting this error on system startup (while on Windows startup logo) indicates that there is a problem in your hard disk boot volume or maybe some kind of drivers. I can’t blame on a single thing and the best way to fix this issue, you can try to use a great Windows tool called “Startup Repair”.

This tool will fix your Operating System in just a couple of minutes and make everything back to normal.

Condition No#2 – Fixing Error While Working or After Startup

Normally according to this condition, “SYSTEM THREAD EXCEPTION NOT HANDLED” Error caused by the corrupted drivers of your computer but sometimes, it also occurred by some another connected external device of your system, like a printer or a scanner etc.

Step 1 – Fixing Things by Removing External Devices

So first, if you are having any external devices connected to your computer then now you should need to unplug all of it, and after that test your computer properly.

If the problem is gone by removing the external devices from your computer then the problem is 100% coming from the corrupted drivers of some particular external hardware and In case, if the problem still remains, then just continue with this article and now I’m going to show you how to troubleshoot the corrupted drivers situation to know which one of your computer driver is creating the problem.

Step 2 – Analyzing the Drivers

Now the thing which I want you to do is to analyze your blue screen dump error and by doing that, it will clarify you that which driver is causing this problem and need to get repaired. Mainly you will only need to find the driver’s name which is most of the time listed on the right side after the errors name.

The driver’s file name which is creating the problem looks like XXX.sys or XYZ.sys, whatever it called but that driver file is having the .sys extension at the end of its name.

After finding the name, now it’s going to be a lot easier to download that particular corrupted driver;

If your BSOD error only shows you the main error name without any .sys file after it, then skip this whole “Analyzing the Drivers” step and move on to the next step “Step 3 – Let’s See What to Do Now” because now you’ll need to try to download and update all of your system drivers and some other Windows repairing stuff too, in order to fix this problem.

This is how your system’s corrupted drivers name looks like:

The next thing you’ll need to do after finding the driver’s file name in your blue screen error is to find that driver file on the driver’s directory to get the full information about it, like its full name or for which thing that driver is actually used for like something.

Here’s a great website which I’m listed down below where you can easily find your driver’s information by searching the .sys drivers file name on it.

So open the link given below and search for your driver’s name.

Drivers Directory ->

For example, I’m taking a driver’s file name “atikmdag.sys” and when I search that file on that directory website, it shows me the full description about that driver’s file as you can see in the picture given below:

According to the example, It’s a display card drivers which is creating the problem as you can see its information in the information column;

Step 3 – Let’s See What to Do Now;

If you know your corrupted driver’s name by the blue screen analyzing trick then that’s great and in case, if you don’t know which one your drivers is creating the problem, then you still don’t have to worry about it because in this article I covered both of those conditions to help you out in a better way.

@Sub Condition No. 1 – What To Do If Your BSOD Won’t Shows You Any Driver’s File Name On It?

There is 10% possibility that your computer can’t be able to show any drivers name with the error message and just only showing you the “System Thread Exception Not Handled” on the screen.

Not showing the drivers name means that your computer or laptop isn’t actually able to identify that driver which one is corrupted and creating this problem.

In that case, you can still fix your PC but in this condition, you’ll have to contribute some few extra efforts of yours.

So, to fix this error according to this condition, you’ll just need to follow all the instruction given in the article linked given below, and come back to this article again if nothing works for you.

@Sub Condition No. 2 – What To Do If Your BSOD Do Shows You Some Driver’s Name On The Error Message?

It’s good to know the faulty driver’s name because that’s gonna help you to quickly fix your problem. So, now I want you to uninstall that particular driver from the device manager of your Windows and after that, install back the latest version.

And yes, you need to download the latest drivers from the internet. This link will help you for that >> How To Find And Download Drivers Online?

So, to uninstall the drivers you’ll need to open the device manager by using “Windows + R” keys on your keyboard to open the Run dialog box and after that type the command “devmgmt.msc” and click OK.

When it’s got open, search for your corrupted driver which is normally listed under their related category. I means if you’ve found your display’s driver is corrupted through analyzing then you’ll need to uninstall your display’s driver which you can find under the display adapters category or maybe if you’ve found your network drivers got corrupted like LAN or Wi-Fi drivers then you’ll need to uninstall your network drivers which you can find under the Network adapters category as you can see in the example picture below.

To uninstall the particular driver, you’ll just need to expand that driver’s category and once it gets expanded, right-click on that driver’s name and click on uninstall drivers.

Restart your computer after the driver’s uninstallation and after that download the latest one and install it properly.

Step 4 – Fixing By Hotfix Only For Windows 7 Or Windows Server 2008
