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.

Tweakbit’s Driver Updater (approved by Microsoft and Norton Antivirus) will help you update drivers automatically and prevent PC damage caused by installing the wrong driver versions. After several tests, our team concluded that this is the best-automatized solution.

Here is a quick guide on how to use it:

1. Download and install TweakBit Driver Updater
2. Once installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.
   
3. Upon scan completion, you get a report on all problem drivers found on your PC. Review the list and see if you want to update each driver individually or all at once. To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.
   
   Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.

Solution 2 – Run the BSOD Troubleshooter

The next thing we’re going to try is running Windows 10’s own troubleshooting tool. This tool can be used for dealing with various system problems, including BSOD issues. So, it might help with the UNEXPECTED KERNEL MODE TRAP issue, as well.

Here’s how to run Windows 10’s troubleshooting tool:

Solution 3 – Run the SFC scan

The SFC scan is another troubleshooter we’re going to try here. This is a command-line tool that scans your system for potentially broken files and repairs them (if possible). Repairing corrupt system files can resolve BSOD issues like the UNEXPECTED KERNEL MODE TRAP error. So, running the SFC scan is definitely worth trying.

Here’s how to run the SFC scan in Windows 10:

1. Right-click the Start Menu button, and open Command Prompt (Admin).
2. Enter the following line and press Enter: sfc/scannow
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.

Solution 4 – Run DISM

Deployment Image Servicing and Management (DISM) is a tool that re-deploys the system image all over again. This can resolve various issues, including BSOD errors.

We’ll walk you through both standard and the procedure that utilizes the installation media below:

• Standard way

2. Paste the following command and press Enter:
   • • DISM /Online /Cleanup-Image /RestoreHealth
3. Wait until the scan is finished.
4. Restart your computer and try updating again.

4. Now, type the following command and press Enter:
   • DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:SourcesInstall.wim:1 /LimitAccess
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.

Solution 5 – Disable uninstall your security software

According to users, sometimes third-party antivirus software can cause this problem to appear. Your antivirus or firewall can interfere with your Windows installation, and in order to fix the problem, you need to disable your antivirus.

If disabling the antivirus or firewall doesn’t fix the issue, you might have to uninstall it. To completely remove your antivirus, it’s recommended to download a dedicated removal tool for it from the developer’s website. After removing the antivirus, check if the problem is resolved.

If removing the antivirus fixes the issue, you can reinstall your antivirus or switch to a different antivirus solution. You can also use Windows Defender instead of a third-party antivirus. Several users reported that Avast was the problem on their PC, but keep in mind that almost any antivirus software can cause this problem to appear.

Solution 6 – Install the latest updates

If you’re getting UNEXPECTED KERNEL MODE TRAP error on your PC, you might be able to fix it by installing the latest updates. To do that, you need to do the following:

1. Open the Settings app. You can do that quickly by using Windows Key + I shortcut.
2. When Settings app opens, navigate to the Update & security section.
   
3. Now click on Check for updates button.
   

Windows will now check for available updates. If updates are available, Windows will download them in the background and install them. Several users reported that their issue was resolved after updating Windows, so be sure to try that.

Solution 7 – Use chkdsk command

According to users, you might be able to fix UNEXPECTED KERNEL MODE TRAP error on your PC simply by running a chkdsk scan. This error can occur due to corrupted files on your hard drive, but you should be able to fix it by doing the following:

Solution 8 – Remove your graphics card driver

According to users, your graphics card driver can be the cause for UNEXPECTED KERNEL MODE TRAP error. Several users reported this issue with the latest Nvidia drivers, and according to them, the solution is to revert to the older drivers.

To do that, simply remove Nvidia driver from Device Manager. If you want to remove all files associated with your graphics card, we wrote a small tutorial on how to use Display Driver Uninstaller, so be sure to check it out.

After removing the driver, Windows will install the default driver once you restart your PC. Now check if the issue reappears with the default driver. Keep in mind that Windows 10 can sometimes update your driver automatically in the background causing the error to reappear. However, you can easily prevent Windows from automatically updating certain drivers.

Solution 9 – Check if your cables are properly connected

In a few cases, users reported that UNEXPECTED KERNEL MODE TRAP error was caused by their hardware. According to them, their connectors weren’t firmly in place, but after properly connecting loose cables, the issue was resolved.

In addition to cables, be sure to check if your RAM is firmly locked in its slot. Few users reported that RAM can be the problem so double check it to see if it’s properly seated.

Solution 10 – Check your RAM

Faulty RAM is a common cause for Blue Screen errors such as UNEXPECTED KERNEL MODE TRAP. However, you can test your RAM to determine if it’s faulty. The simplest way to do that is to remove all but one module from your PC and check if the issue reappears. Now you need to repeat this until you test all modules.

However, if you want to perform a detailed scan, you’ll need to use a tool such as Memtest86+ to test your RAM. Keep in mind that you need to test each module individually. To perform a detailed scan, you need to keep the test running for an hour or so for each module.

Solution 11 – Reset Windows 10

If the problem still appears, you might have to reset your PC. This process will delete all files from your system drive, so be sure to back them up. In addition, you might need a Windows 10 installation media to complete this process, so create it with Media Creation Tool.

To perform the reset, you need to do the following:

1. Start Advanced Startup. We briefly mentioned how to do that in Solution 1, so check it for detailed instructions.
2. Choose Troubleshoot > Reset this PC > Remove everything.
3. You might be asked to insert your installation media to proceed to the next step, so be sure to have it ready.
4. Choose your version of Windows and select Only the drive where Windows is installed > Just remove my files.
5. Now you’ll see the list of changes that reset will perform. Once you’re ready to start, click on Reset.
6. Follow the instructions on the screen to complete the reset.

After finishing the reset, you’ll have a fresh installation of Windows 10 and your problem should be resolved.

If you’re trying to upgrade to Windows 10, you can delete these drivers on your current operating system, and then upgrade to Windows 10 in order to avoid these issues.
