- While Windows Installation – It’s also possible you can seeing this error while installing windows operating system in your computer.
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.
Note: You can skip the whole condition number 1 and move to next if you having the second one.
Condition No#1 – Fixing Startup Error
Getting this error on system startup (on windows starting logo) indicates that there is sometimes problem in your hard disk boot volume or maybe drivers. I can’t blame on a single one so, you’ll need to try both to fix this problem.
When this 0x0000007e error caused by your computer’s or laptop’s HDD that doesn’t mean your Hard disk is dead or broken, its only indicates that it needs some minor repair.
It’s possible your boot volume got corrupted by some recently installed Software, Viruses or Windows/Software updates and it’s better to get it repair as soon as possible.
So, we only need cmd command prompt to repair our hard disk boot volume by just typing some command in it.
Try this linked article to know 4 Different Ways to Run Cmd on Your Computer? Even your windows isn’t running.
Command 1# – Diskpart
Command 2# – List volume
Command 3# – Exit
You’ll need to find your windows drive letter in that list, like mine is 29 GB D: drive.
Now you know what is your drive letter is, so just enter your drive letter in the command prompt and repeat the following command given below.
Command 4# – D: (Your Windows Drive Letter)
Command 5# – Bootrec /fixmbr
Command 6# – Bootrec /fixboot
Command 7# – Chkdsk /f (Try chkdsk /f /r If “Chkdsk /f” command Wont Works)
Command 8# – Y
When the “chkdsk” process completes, restart your computer system and I hope your problem is solved. If not move to the next step.
If repairing boot volume isn’t beneficially for you than its definitely your windows drivers problem and in that condition I what you to try to open your computer in the safe mode and continue with the second condition listed below because it will helps you to fully analyze and repair the problem.

Condition No#2 – Fixing Error While Working or After Startup
Normally this “SYSTEM THREAD EXCEPTION NOT HANDLED” Error caused by the corrupted drivers of your computer or maybe sometimes by another connected external devices like printer or scanner.
If you have an external device connected to your computer then you should unplug it and after that test your computer by using it. If the problem is gone by removing external device to your computer then the problem is 100% coming from the corrupted drivers for that particular hardware or if the problem is still remains then you should continue this article and troubleshoot to know which is creating the problem.
#ANALYZING THE ERROR
Now the first thing a want to do is analyzing your blue screen error and that clarify you, which drivers is causing this problem. Mainly we’ll only need to find the driver’s name which is most of the time listed on the right side after that SYSTEM_THREAD… error name.
The drivers file name which creating problem is be like xxx.sys or xyz.sys whatever it called that has .sys extension at the end of that drivers name. After finding the name it’s going to be easy to download that corrupted driver.
If your error only shows you the main error name without any .sys file after it, then skip this “#ANALYZING THE ERROR” step and move on to next step #Repairing drivers because now you’ll have to download and update all of your drivers in order to fix this problem.
The next thing you’ll need to do after finding the drivers file name in your blue screen error is to find that driver file on the drivers directory to get the full information about that particular drivers like, finding their full name, what is that drivers etc.
Here’s a great website I’m listed below where you can easily find your driver’s name by searching the .sys drivers file name in it. So open the link given below and search for your driver’s name.
For example I’m taking my corrupted drivers name is “atikmdag.sys” and when I search searching it on that website, it shows me the full description about my drivers file which is creating problem as you can see below.
So, it’s my display drivers who are creating the problem as you can see in the information column:
So, now we need to repair our drivers and if you knows your drivers name by the blue screen analyzing trick that’s great and if you don’t know which one your drivers is creating problem then don’t worry about it I covered both of that conditions.
Note: We need an opened operating system in order to repair drivers, if your computer won’t able to start normally or maybe this error showing after 10 or 15 seconds of your windows start then I highly recommend you to open your windows in safe mode. If your windows working properly and this error shows in middle of something then you can continue without opening your computer in safe mode.
It’s good to know your faulty drivers 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.
To uninstall drivers you’ll need to open the device manager by using “Windows + R” hotkeys to open the Run dialog box and after that type the command “devmgmt.msc” and click OK.
When it’s get open, search for your driver who’s corrupted and listed under their related category. I means if you’ve found your display 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 driver which you can find under the Network adapters category as you can see in the example picture below.
To uninstall that drivers, you’ll just need to expand that driver’s category and once it gets expanded, right-click on the driver name and click on uninstall drivers.
Restart your computer after drivers uninstalling and after that download the latest version of that driver and install it properly.
If your error won’t shows any drivers file name then you can try to fix this error by uninstalling the display’s drivers first and if that won’t work’s also you’ll need to update all of your system’s drivers.
So, to uninstall your display’s driver, you’ll need to open the device manager by using “Windows + R” hotkeys to open the Run dialog box and after that type the command “devmgmt.msc” and click OK.
When it’s get open, search for your display’s driver which is listed under their related category. To uninstall that driver, you’ll just need to expand that display adaptor drivers category and once it get expanded, right-click on the driver name and click on uninstall drivers.
If uninstalling videos or I say display’s drivers wont works for you then you’ll need to update all of your system’s drivers without uninstalling any single one from the device manager.
Note: Don’t uninstall any other driver from the device manger beside the graphic one. And also install the latest graphic drivers for your computer after uninstalling the old once.
