  6. Windows 10 will now locate and download the appropriate driver.
    browse-my-for-driver-software
  7. Repeat these steps for all drivers that you wish to update.

Drivers are often the cause for BSoD errors since they are used by Windows in order to communicate with your hardware.

If a certain driver is out of date, Windows 10 won’t be able to work with specific hardware, and that will give you UNSUPPORTED_PROCESSOR or any other BSoD error.

In order to avoid these types of problems, it’s recommended to update your drivers.

Updating your drivers is simple, and all you need to do is to visit your hardware manufacturer’s website and download the latest drivers for your hardware.

Alternatively, you can use device Manager to update all the necessary drivers. To update drivers by using Device Manager you need to do the following:

Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically.

Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up to date with the latest drivers.

  3. Select BSOD from the right pane and click Run the troubleshooter.Troubleshooting
  4. Follow the instructions on the screen to complete the troubleshooter.

If none of the previous solutions resolved the issue, let’s try a few troubleshooting tools. The first troubleshooter we’re going to try is Windows 10’s built-in BSOD troubleshooter.

As you can probably tell, this tool can address all sorts of BSOD problems. Hopefully, the UNSUPPORTED_PROCESSOR error is one of them.


6. Run the SFC scan

  1. Right-click on the Start Menu button, and open Command Prompt (Admin).
  2. Enter the following line and press Enter: sfc/scannowCommand Prompt
  3. Wait until the process is done (it may take a while).
  4. If the solution is found, it will automatically be applied.
  5. Now, close the Command Prompt and restart your computer.

The next troubleshooting tool we’re going to try is the System File Checker. This tool scans your computer for potential issues and resolves them automatically (if possible).

So, if the UNSUPPORTED_PROCESSOR error is caused by a corrupt system file, the SFC scan will deal with it.


7. Run DISM

  1. Right-click Start and open Command Prompt (Admin).
  2. Paste the following command and press Enter: DISM/Online/Cleanup-Image/RestoreHealthAdministrator Command Prompt cleanup

And the third troubleshooting tool we’re going to try is DISM. Deployment Image Servicing and Management (DISM), as its name says, re-deploys the system image, and resolves potential issues along the way.

So, it could also resolve the UNSUPPORTED_PROCESSOR error. We’ll walk you through both standard version, shown above, and the procedure that utilizes the installation media below.

With the Windows installation media

  1. Insert your Windows installation media.
  2. Right-click the Start menu and, from the menu, choose the Command Prompt (Admin).
  3. In the command line, type the following commands and press Enter after each: dism/online/cleanup-image/scanhealth dism/online/cleanup-image/restorehealth

  5. Make sure to change an X value with the letter of the mounted drive with Windows 10 installation.
  6. After the procedure is finished, restart your computer.

8. Check the hard drive

  1. Enter the Advanced Startup (Restart your computer while holding the Shift key).
  2. Choose Troubleshoot > Advanced Options.
  3. Select Command Prompt from the list of options.
  4. When Command Prompt appears, enter the following lines and press Enter after each line in order to run it: bootrec.exe /rebuildbcd bootrec.exe/fixmbr bootrec.exe /fixbootINVALID SOFTWARE INTERRUPT Windows 10 error
  5. Some users are also suggesting that you need to run additional chkdsk commands as well.
    • To perform these commands, you need to know drive letters for all your hard drive partitions.
  6. In Command Prompt you should enter the following (but remember to use the letters that match your hard drive partitions on your PC): chkdsk/r c: chkdsk/r d:INVALID SOFTWARE INTERRUPT Windows 10 error
    • This is just our example, so keep in mind that you have to perform chkdsk command for every hard drive partition that you have.
  7. Restart your computer afterward.

If your hard drive is damaged, BSOD issues are more than possible. To eliminate the doubt, you should run the chkdsk, which scans all your partitions and resolves potential problems (if possible).

So if the culprit of the UNSUPPORTED_PROCESSOR is a corrupt hard drive, this tool will likely resolve the problem.

    • Now you can enable all applications and services one by one until you find the one that is causing you trouble.

Often incompatible software can cause UNSUPPORTED_PROCESSOR error and this is why it’s necessary to find the problematic software and uninstall it.

If you installed any new software before this error started appearing be sure to uninstall it. In addition, you can also disable all startup applications in order to find the problematic app.

It’s also worth noting that your antivirus can be the common cause for all sorts of BSoD errors, so be sure to uninstall any third-party antivirus software that you have installed.

Uninstalling antivirus software might not be enough, so you’ll have to download and use a dedicated removal tool.

10. Check for hardware problems

UNSUPPORTED_PROCESSOR error along with many other BSoD errors can be caused by hardware problems.

If you installed any new hardware recently be sure to remove it or replace it and check if the problem is fixed.

To perform this step, you might need some spare components, and possibly some expert help, so you might want to take your PC to the repair shop.

UNSUPPORTED_PROCESSOR BSoD error usually appears when your processor doesn’t support the necessary instructions required for Windows 10 run properly.

So be sure to check if your processor meets the hardware requirements and if it works properly.

We also suggest checking all of your fans for dust and cleaning them accordingly. Overheating is also a cause for system failure, so you need to watch out for clogged fans.

Just thought I’d add my 2 cents on this since I just ran into this issue but just a slightly different scenario. My processor (intel i7 4790k) has been working in my computer for about 3 years now with no issue. However, I recently had a windows update which produced this error and I was unable to get into Windows. The PC would boot up and it would just give me that error on the BSOD and then reboot in a loop indefinitely. After trying several different things I finally found out that the latest windows update somehow was not compatible with my MOBO firmware. I have an ASUS Z97-AR and after a quick BIOS update via the Asus EZ Flash 2 utility in the BIOS I downloaded the latest firmware on a USB drive used the EZ Flash 2 tool and updated the BIOS that way. After that it booted up again like a charm! Hope this helps for anyone else that may be having a similar scenario. Thanks for the great article as well!
