Method # 1 Updating / reinstalling the problematic driver

The SYSTEM THREAD EXCEPTION NOT HANDLED blue screen of death may occur as a result of incorrect operation of the driver for a device in the user’s computer. The video card driver is often the culprit, but it can be just about any driver installed on the system, such as a sound card or USB speaker driver. You need to do the following: enter your OS in Safe Mode, open Device Manager and update / reinstall the problematic drivers.

To enter Windows 10 Safe Mode, you will need to use the Windows 10 installation media. this link on the official Microsoft website for the steps to create such media. Once you have media, try the following:

  • insert the installation media into your computer and restart it;
  • press any button on the keyboard as soon as the corresponding message appears;

The note: you may need to go into your BIOS settings and set the boot priority to the USB port or CD / DVD drive, otherwise you will not be able to boot the installation media.

  • select the language, date and time format, and input type, and then go to the Windows 10 setup screen;
  • instead of the “Install” button, click on the “Restore System” button;
  • Once in the Windows 10 Recovery Environment (Windows RE), go through the following path:
    • ↓ Diagnostics (Troubleshooting);
    • ↓ Additional parameters;
    • ↓ Download parameters;
  • click on the “Restart” button in the lower right corner;
  • then press the F5 button on the keyboard in order to enter safe mode with loading network drivers.

Everything, you should have logged into your OS without any problems. Now we need to call the Device Manager in front of us and start updating or reinstalling problem drivers. Try the following in safe mode:

  • press Windows + R;
  • specify in an empty line devmgmt.msc and press Enter;
  • carefully examine the list for devices with a yellow exclamation mark – this will mean that something is wrong with their driver; if there are no signs in the list, then go to your video card and double-click on its LMB;
  • go to the “Driver” tab and click on the “Update” button;

You need to go to the Device Manager again, right-click on the desired device and select the “Remove device” option.

Then we go to the official website of the manufacturer, download the installer of the fresh driver and install it on the system. We reboot and look at the fruits of our labors. Reinstall drivers for other devices as well.

Method # 2 SFC and CHKDSK

In frequent cases, blue screens of death occur due to damaged Windows 10 system files or the presence of errors on the HDD / SSD. Here funds such as SFC and CHKDSK come to the rescue. Usually, they are launched directly from the system, but this time we will have to do it through the Windows RE on the installation media. Try the following:

  • get to advanced options in Windows RE;
