How can I fix this bluescreen? Don't personally understand it and really not sure about what to do. I have tried a full reset of the PC and the issue persists.

The HYPERVISOR_ERROR Blue Screen of Death (BSOD) is typically associated with problems in the virtualization software running on Windows, like Hyper-V, or issues with hardware virtualization settings. It could also be triggered by driver conflicts or hardware malfunctions. Here are several steps you can follow to troubleshoot and potentially resolve this issue:

1. Update Windows and Drivers​

  • Windows Update: Ensure your Windows is up to date. Go to Settings > Update & Security > Windows Update and check for updates. Installing the latest updates can fix bugs related to the operating system and virtualization features.
  • Driver Updates: Update all relevant drivers, especially those for your chipset and graphics card. You can find these on the manufacturer’s website or through Device Manager in Windows.

2. Check Virtualization Settings in BIOS​

  • Access BIOS/UEFI: Restart your computer and enter the BIOS/UEFI settings. This is usually done by pressing a key such as F2, DEL, or ESC as the computer starts up.
  • Virtualization Settings: Look for settings related to virtualization, such as Intel VT-x, AMD-V, or Virtualization Technology. Ensure they are enabled. If they are already enabled, try disabling them, save the settings, boot into Windows, then restart and re-enable them to reset the settings.

3. Disable Hyper-V or Other Virtualization Software​

  • If you are using Hyper-V, VMware, or any other virtualization software, consider temporarily disabling it to check if the issue persists:
    • Disable Hyper-V: Open Command Prompt as Administrator and type dism.exe /Online /Disable-Feature:Microsoft-Hyper-V. You will need to restart your computer.

4. Check System Files and Memory​

  • System File Checker: Run the System File Checker to repair corrupted Windows files. Open Command Prompt as Administrator and type sfc /scannow.
  • Memory Test: Use Windows Memory Diagnostic to check for memory issues. Type Windows Memory Diagnostic into the start menu and choose to restart now and check for problems.

5. Perform a Clean Boot​

  • Clean Boot: Perform a clean boot to see if third-party software is causing the issue. Type msconfig in the start menu and open System Configuration. Under the Services tab, select Hide all Microsoft services, then click Disable all. Under the Startup tab, open Task Manager and disable all startup items. Restart the computer.

6. Check for Hardware Issues​

  • Since the problem persisted even after a full reset, there might be underlying hardware issues. Consider running diagnostics on your CPU and motherboard if available. Some manufacturers provide built-in diagnostic tools that you can access during startup.

7. Restore or Reinstall Windows​

  • System Restore: If the problem started recently, use System Restore to go back to a previous state before the issues began.
  • Reinstallation: If none of the above steps work, consider backing up your data and performing a clean installation of Windows.
If the error continues despite these troubleshooting steps, it might indicate a deeper hardware issue, possibly with the CPU or motherboard. In such cases, it may be necessary to contact a professional technician or your computer’s manufacturer for further assistance.
