If you’re facing the issue of System Thread Exception Not Handled Code on your computer, don’t worry! We’ve got you covered with a quick and easy fix.
Starting in Safe Mode
Starting your computer in Safe Mode is a great way to troubleshoot and fix the system thread exception not handled code error. To do this, follow these steps:
1. Restart your computer and press the F8 key repeatedly until the Advanced Boot Options menu appears.
2. Use the arrow keys to select Safe Mode and press Enter.
3. Once in Safe Mode, you can try to fix the error by updating your drivers, scanning for malware, or restoring your system to a previous state.
4. To view the details of the error, check the Event Viewer for any related entries.
Starting your computer in Safe Mode will prevent any unnecessary programs or drivers from running, which can help you isolate and fix the problem. If you’re experiencing a boot loop or other issues preventing you from accessing Safe Mode, try booting from a Windows installation drive and using the repair options.
Remember to always backup your important files before attempting any fixes.
Identifying the Problematic Driver
- Use Safe Mode to boot your computer.
- Restart your computer.
- Press the F8 key repeatedly until the Advanced Boot Options menu appears.
- Select Safe Mode and press Enter.
- Open Device Manager.
- Press the Windows key + X and select Device Manager.
- Alternatively, press the Windows key + R, type devmgmt.msc and press Enter.
- Identify the problematic driver.
- Look for any device with a yellow exclamation mark.
- Note the name of the device and its driver.
- Update or disable the problematic driver.
- Visit the website of the device manufacturer to download and install the latest driver.
- Right-click on the problematic device and select Properties.
- Select the Driver tab.

Updating or Reverting Drivers
To fix the system thread exception not handled code, updating or reverting drivers may be required. Start by accessing the Device Manager and identifying any drivers with a yellow exclamation mark indicating an issue. Right-click the driver and select “Update Driver.” If that doesn’t work, try reverting the driver to a previous version. Navigate to the driver’s properties and select the “Driver” tab. Click “Roll Back Driver” if it’s available. If not, uninstall the driver and then reinstall the previous version. Be sure to download the correct driver from the manufacturer’s website. If the issue persists, check the Event Viewer for more information. A kmode exception or nvlddmkm sys error may indicate a graphics card issue. In some cases, a boot loop may occur. Check for a handled ntfs sys error in this case.
Renaming the Faulty File
To rename the faulty file causing the System Thread Exception Not Handled code, follow these steps:
1. Restart your computer and enter Safe Mode by pressing F8 repeatedly during startup.
