How do I fix IRQL GT ZERO AT SYSTEM SERVICE error?

Solution 1 – Download Windows updates regularly

These types of errors are usually caused by incompatible hardware or software, therefore it’s crucial for you to run Windows Update and to download the latest updates. Many of these updates come with new features, but in addition to new features, Windows updates often fix many software or hardware related issues, and since IRQL GT ZERO AT SYSTEM_SERVICE error is caused by these issues, it’s crucial for you to keep Windows 10 up to date.

Solution 2 – Update your drivers

Drivers are an essential component of every operating system, and if your drivers are outdated or corrupted, you might get IRQL GT ZERO AT SYSTEM SERVICE error. In order to avoid these types of errors, it’s highly advised to update your drivers frequently. Updating your drivers is relatively simple, and the easiest way to do it is by using Device Manager.

Using the Device Manager to update drivers might not always be the best solution, but you can always download all the necessary drivers directly from your hardware manufacturer. Your hardware manufacturer will have the latest drivers, and in order to download them simply visit its website, locate the model of the device you want to update and download all the necessary drivers for it. Bear in mind to update as many drivers as you can in order to avoid any BSoD issues.

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 Updaterdriver updater starting window
  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 Once installed, the program will start scanning your PC for outdated drivers automatically.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.

    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 3 – Run the BSOD Troubleshooter 

Another thing we can try is running Windows 10’s built-in troubleshooting tool. This tool is designed to deal with various system issues, including BSODs. So, it might be helpful in this case, as well.

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

  1. Right-click on the Start Menu button, and open Command Prompt (Admin).

  4. If the solution is found, it will automatically be applied.
  5. Now, close the Command Prompt and restart your computer.

Solution 5 – Run DISM

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

  • Standard way

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

  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 /rebuildbcdIRQL GT ZERO AT SYSTEM SERVICE Windows 10 error
    • bootrec.exe /fixmbr
    • bootrec.exe /fixboot
  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. 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:IRQL GT ZERO AT SYSTEM SERVICE Windows 10 error
    • chkdsk /r d:

    This is just our example, so keep in mind that you have to perform chkdsk command for every hard drive partition that you have.

  6. Restart your computer and check if the issue is resolved.

Solution 7 – Uninstall problematic software

According to users, IRQL_GT_ZERO_AT_SYSTEM_SERVICE error can often be caused by problematic software, and in order to fix this issue, it’s advised to locate and remove the problematic application.

Often cause for these types of errors is your antivirus software, and many users reported issues with Bitdefender, so it’s highly recommended that you uninstall it. In addition to uninstalling Bitdefender, you should use the dedicated uninstaller tool to completely remove it.

Many antivirus programs leave certain files and registry keys after you uninstall them, and in order to completely remove antivirus software from your PC and fix the IRQL GT ZERO AT SYSTEM_SERVICE error, it’s important to use the proper uninstaller tool. Many security companies offer these tools for download, so be sure to get one.

It’s worth mentioning that almost any antivirus tool can cause a BSoD error, and in order to fix this problem it’s recommended to remove all third-party antivirus tools. Even if you remove your antivirus tool, you computer still has Windows Defender, so you won’t be completely unprotected.

In addition to antivirus, many users reported that other software, such as SoundTap, NCH Software Suite or even Bluestacks and Andy OS can cause IRQL GT ZERO AT SYSTEM SERVICE error. In order to fix this issue, it’s highly recommended to remove the aforementioned software. If you need to use any of these tools, you can try installing the latest version that hopefully doesn’t have the same issues.

These are just some common causes for this error, and bear in mind that almost any application can cause this error to manifest, so be sure to remove any application that you installed or updated in the last couple days or weeks.

Solution 8 – Disable Hyper-V

Many users are claiming that disabling Hyper-V in Windows 10 fixes the IRQL GT ZERO AT SYSTEM SERVICE error. Disabling Hyper-V is rather simple, and you can do it by following these steps:

  1. Press Windows Key + S and enter windows features. Select Turn Windows features on or off.
    advanced-features
  2. Once the Windows Features window opens, locate Hyper-V and uncheck it.
    hyper-v
  3. Click OK to save changes.

After disabling this feature problems with IRQL GT ZERO AT SYSTEM SERVICE should be resolved.

Solution 9 – Update your BIOS

In some cases these types of errors can appear if your BIOS is out of date, and in order to fix this problem it’s advised to update BIOS. Updating BIOS is an advanced procedure, and if you decide to perform it, we advise you to be extra careful.

To see how to update your BIOS, you need to check your motherboard manual for detailed instructions. As for required files, you can download the latest BIOS for your motherboard from your motherboard manufacturer’s website. Bear in mind that you can cause permanent damage to your PC if you don’t update BIOS properly, therefore be extra careful.

Solution 10 – Check for hardware problems

As we already mentioned, BSoD errors can be caused by faulty hardware, so it’s advised to check if your hardware is working properly. If you installed any new hardware recently, you need to remove it or replace it and check if your PC is working without it.

In addition to removing new hardware, you need to check if your current hardware is working properly. The most common cause for this error is RAM, and in order to check RAM you’ll need to use a tool such as MemTest86+. Simply move the tool to a USB flash drive, boot your PC from it and let it test your memory for few hours.

If your memory is working properly, you might want to check if other hardware components are working correctly. Finding a faulty component might be difficult, so you might want to contact an expert.

If you’re still having issues with your hardware or you simply want to avoid them for the future, we also recommend you to download this tool (100% safe and tested by us) to fix various PC problems, such as hardware failure, but also file loss and malware.

IRQL GT ZERO AT SYSTEM SERVICE error can be troublesome, but in most cases this error is caused by a problematic software, and removing the problematic software will fix the issue in most cases.
