If you have already downloaded the driver from the manufacturer’s website, select this option and navigate to the location where you saved the driver.


5. If Windows is unable to find an updated driver, you can try visiting the manufacturer’s website to download and install the driver manually. To do this, search for the manufacturer’s website and navigate to the “Support” or “Downloads” section. From there, find the driver for your device and download it.

6. Once you’ve downloaded the updated driver, double-click on the downloaded file to begin the installation process. Follow the prompts to install the driver.

It’s important to note that some device drivers may require you to restart your computer after installing the update. If this is the case, be sure to save any unsaved work before restarting your computer.

Overall, updating your device drivers can help improve the performance and compatibility of your computer’s hardware. It’s recommended to check for updates regularly and install them as needed.

b. How do outdated device drivers cause System Thread Exception Not Handled error?

The “System Thread Exception Not Handled” error is a Blue Screen of Death (BSOD) error that can occur on Windows computers. This error is often caused by a driver-related issue.

When a device driver is outdated or incompatible with the operating system or other hardware components, it can cause conflicts and errors that may result in a BSOD error such as “System Thread Exception Not Handled”. This can happen when the driver tries to access a memory address that is already being used by another process or when it encounters an unexpected error.

For example, if you have an outdated graphics card driver and you try to run a game or other graphics-intensive application, the driver may encounter errors that cause a BSOD error. Similarly, if you have an outdated network driver and you try to connect to the internet or another network, the driver may cause conflicts that result in a BSOD error.

In some cases, the “System Thread Exception Not Handled” error may also be caused by other factors such as malware, hardware issues, or software conflicts. However, outdated or incompatible device drivers are a common cause of this error.

To resolve this error, you can try updating your device drivers to the latest version. This can help ensure that the drivers are compatible with your operating system and other hardware components, and may resolve any conflicts or errors that were causing the BSOD error.

3. Disable overclocking:


Overclocking is a technique used to increase the performance of a computer’s hardware components, such as the CPU or GPU, beyond their factory settings. While overclocking can provide a boost in performance, it can also cause stability issues and increase the risk of hardware damage.

a. How to disable overclocking?

To disable overclocking on a computer, you need to access the BIOS (Basic Input/Output System) settings. Here are the general steps to disable overclocking:

  1. Restart your computer.
  2. During the boot-up process, press the key that allows you to access the BIOS setup. This key is different for each computer manufacturer, but it is often one of the following: F2, F10, F12, Del, or Esc. Refer to your computer’s manual or the manufacturer’s website for more information on how to access the BIOS setup.
  3. Once you are in the BIOS setup, look for options related to overclocking. These options may be located under a menu called “Advanced” or “Performance”.
  4. Disable any overclocking options by setting them to their default values. This may involve setting the CPU ratio or frequency to its default setting, or disabling any features related to overclocking.
  5. Save the changes and exit the BIOS setup. This will typically involve pressing the F10 key or selecting “Save and Exit” from a menu.
  6. Your computer will now restart with overclocking disabled.

It’s important to note that disabling overclocking may result in a decrease in performance for some tasks, as the hardware components will be running at their default settings. However, this can help improve stability and prevent damage to the components, particularly if you have been experiencing issues related to overclocking.

b. Why does overclocking cause System Thread Exception Not Handled error?

Overclocking can cause the “System Thread Exception Not Handled” error because it increases the demand for power and thermal management, which can cause the hardware components to overheat or malfunction. Additionally, it can cause issues with the system’s timing and synchronization, which can lead to errors and crashes. To avoid these issues, proper overclocking techniques should be followed and the system’s performance and temperature should be monitored carefully.

4. Run system file checker:


The System File Checker (SFC) is a tool in Windows that can scan and repair corrupted or missing system files. Running the SFC can help fix issues that may be causing the “System Thread Exception Not Handled” error.

a. What is system file checker?

The System File Checker (SFC) is a built-in tool in Windows that is used to scan and repair corrupted or missing system files. System files are essential files that are used by the operating system to run and manage the computer. These files can become corrupted due to various reasons, such as malware infections, hardware failures, or software issues.

The System File Checker works by scanning all the protected system files on your computer and comparing them to a cached copy stored in the Windows directory. If the tool detects any discrepancies between the cached copy and the actual file on your computer, it will attempt to repair or replace the file with a cached copy.

The SFC can help fix issues that may be causing problems on your computer, such as system crashes, BSOD errors, or performance issues. Running the SFC is a simple process and can be done using the Command Prompt with administrative privileges. However, it’s important to note that the SFC may not always be able to repair all system file issues and may require additional troubleshooting or repair methods.

b. How to run system file checker?

  1. Open the Command Prompt as an administrator. To do this, right-click on the Start menu button and select “Command Prompt (Admin)” from the list of options.
  2. In the Command Prompt window, type “sfc /scannow” and press Enter. This will start the system file checker scan.
  3. Wait for the scan to complete. This can take some time, depending on the size and complexity of your system files.


4. Once the scan is complete, the SFC will report any issues it found and attempt to repair them automatically.

5. Restart your computer to complete the repair process.

It’s important to note that if the SFC is unable to repair the corrupted files, you may need to use other tools or methods to fix the issue. Additionally, it’s recommended to run the SFC regularly to ensure that your system files are in good condition and that your computer is running smoothly.

5. Perform a clean boot:


Performing a clean boot in Windows is a troubleshooting technique that can help identify and resolve issues that may be causing the “System Thread Exception Not Handled” error. Here are the steps to perform a clean boot:

  1. Press the Windows key + R to open the Run dialog box.
  2. Type “msconfig” and press Enter. This will open the System Configuration window.
  3. Click on the “Services” tab and check the box next to “Hide all Microsoft services”. This will prevent any essential Windows services from being disabled.
  4. Click on the “Disable all” button to disable all non-Microsoft services.


5. Click on the “Startup” tab and click on the “Open Task Manager” button. This will open the Task Manager window.

6. Disable all startup programs by right-clicking on each program and selecting “Disable”.

7. Close the Task Manager window and click on “OK” in the System Configuration window.

8. Restart your computer to apply the changes.

Once your computer has restarted, it will be in a clean boot state, with only essential Microsoft services running. If the “System Thread Exception Not Handled” error does not occur in this state, it may be caused by a third-party program or service. You can then use a process of elimination to determine which program or service is causing the issue and either uninstall it or disable it permanently. If the error still occurs in a clean boot state, it may be caused by a hardware issue, and you may need to perform additional troubleshooting or seek professional assistance.
