A handy step-by-step guide to fix unhandled system threads exceptions in the Windows operating system.
If you are using a Windows operating system, many annoying problems and errors can occur.
Blue death screen (or BSOD) is one of them. This is a common Windows error that usually occurs on your computer when something goes wrong.
If BSOD is displayed, it indicates that the computer is disabled and locked on the BSOD screen (blue screen, error message and stop code display) and a restart is required.
Depending on your computer settings, your Windows computer may restart automatically.
The entire Windows operating system recovers automatically, and Windows may boot normally, but in most cases it is not.
A blue screen error has occurred, or a restart loop has occurred. The circle starts with a blue screen and an error message and stop code are displayed.
After that, the computer restarts. Try running the Windows operating system. The blue screen will be displayed again. Repeat!
How to fix the original error system error
In most cases, this error is due to the graphics card driver not being updated. You need to update your video card driver to the latest version.
However, there are other issues that can cause this error such as disk corruption, driver corruption, BIOS corruption, Windows system file corruption, missing Windows registry entries and more.
Fortunately, I found several ways to resolve this error. These forms are helpful based on Microsoft community users and readers of this blog.
Repair corrupted driver to fix first system thread BSOD error exception
Problems with computer drivers can cause “non-manual exceptions” on system threads.
If you still have access to a Windows computer (usually after running BSOD and running on a Windows operating system), you can check and locate the corrupted driver in Device Manager.
If a troubleshooting program is found, delete it and replace it with a new one or update to the latest version.
The next step is to look for defective drivers or hardware that has corrupted drivers. You need to update these drivers to the latest version, or delete them and replace them with new ones.
What if I can not access the Windows operating system?
After a BSOD error occurs, the computer will restart automatically.
However, the Windows operating system can not be accessed, and the computer restarts many times (the restart as mentioned earlier cycle).
In this case, you need to log in to the computer in safe mode and then remove the driver card driver.
Once the removal process is complete, you need to download the latest video card driver from the official website and install it on your computer.
Go to Windows 8 / 8.1 Safe Mode and uninstall the video card driver
According to user reports, system_thread_exception_not_handled usually appears on Windows 8 / 8.1. So I will show you how to call Safe Mode in Windows 8, 8.1 and remove the video card driver to fix the unresolved system thread exception.
Tip: You can also use the BSOD analysis tool (e.g., BlueScreenView or WhoCrashed) to find out the mini dump file on Windows computer and to figure out the cause of this annoying problem.
Restart your computer and hold the Shift key while pressing the F8 key repeatedly until the recovery screen appears.
You can also use the Restore System button (or DVD) to access the troubleshooting screen (in step 2) and press F8.
Click “Troubleshooting”-> “Advanced”-> “Windows Startup Options”-> “Restart”.
When you restart your computer, the Advanced Boot Options screen appears, where you can select Safe Mode, Safe Mode with Network Support, or Use Command Prompt Safe Mode.
Select “Safe Mode” and start your Windows computer.
When logging into your computer, go to the Device Manager (listed above) to remove the video card driver. Then restart your computer to apply the changes.
If you can access the computer normally, please download the latest video card driver from the official website and install it on your computer.
Find and Repair Corrupted System Files on Windows Operating System
Corruption of Windows operating system files can cause this error and many other issues.
To resolve this issue, use the CHKDSK command to check and validate Windows system files to ensure that the files are not corrupted. This command is also useful for repairing corrupted files.
First, run the command line as an administrator by pressing Windows + X and then A.
Write in the next step:
CHKDSK C: / F / R.
Then press Enter.
In the next step, enter J and press Enter.
Then restart your Windows computer.
The Windows computer starts and starts scanning for corrupted files and scanning of the entire system.
This process will take some time. Therefore, do not turn off power while monitoring a computer.
Find and repair Windows system files to fix system thread exception error
Scanning and restoring Windows system files may fix many errors on your computer. To do this, open the command line utility as an administrator using the section above.
Write in the next step:
SFC / scan
Then press Enter. Automatically scan and fix all errors on your Windows computer. Wait for the process to complete and restart your computer.
Other tips that can be useful
If the system file contains BSOD errors (for example, unmanaged system stream (dxgkrnl.sys) exception), you can copy this file name and view it on carrona.org.
Displays the name of the application or built-in function that contains this .sys file. Therefore, you can easily identify the root cause of the problem and find a way to eliminate non-multisystem system errors quickly.
If you find a driver, you can remove it and fix the problem. Then restart and reinstall your computer. Your driver is sometimes corrupted and causes this annoying error.
If you can not start your Windows computer, enable Safe Mode. You can also boot the computer from the recovery device, access the command line, and run the following command:
CD Windows Driver 32
Ren dxgkrnl.sys dxgkrnl.old
If another .sys file appears on the screen, replace it with the correct file.
After executing the above command, please restart your Windows computer. Let’s get started now. Next, download and install the driver renamed with the previous command.
You can also use Windows System Restore or Backup and Restore to a Windows computer (if these features are enabled).
As mentioned above, disk, BIOS corruption, or missing Windows registry entries may be the cause of this error.
Therefore, make sure your hard drive is working properly and restore the BIOS settings to resolve this issue.
If there is a problem with the Windows registry, you need to use an analysis application to check and control the registry as TuneUp.
