There have been reported cases by some PC users encountering the DRIVER_IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error with the Xhunter1.sys file identified as the culprit on their Windows computer. Xhunter1.sys is a third-party driver file used by the XIGNCODE3 System Guard anti-cheat engine.

Affected PC users reported the error occurs in different instances. One such report stated the error occurs when trying to login into a game after instantly closing the game or after some work in other applications. Other reports stated the BSOD error occurs when a particular game (eg; Blade and Soul, PUBG) is started or while playing the game on the computer. In any case, this post offers solutions to this error.

Fix Xhunter1.sys Blue Screen error

If you have encountered the xhunter1.sys BSOD error while performing certain tasks or launching or playing specific games on your Windows 11/10 PC, then our recommended solutions presented below in no particular order if applied rightly should help you resolve the issue on your system.

1. Install the xhunter1.sys driver in Compatibility Mode
2. Delete the xhunter1.sys file
3. Temporarily disable Driver Signature Enforcement and/or Memory Integrity
4. Disable Paging File
5. Troubleshoot using WinDbg
6. Reinstall the game.

Let’s see the solutions in detail. If you can log in normally, that’s great; otherwise, you’ll need to boot into Safe Mode, access the Advanced Startup options screen, or use the Installation Media to carry out these instructions.

1] Install the xhunter1.sys driver in Compatibility Mode

Chances are the xhunter1.sys driver file is incompatible with the latest iterations of the Windows OS which seems to be the case here as reported by affected PC users. In this case, to see if the issue in view is resolved, you can install the xhunter1.sys driver in Compatibility Mode by following these steps:

• Right-click the driver setup file.
• Select Properties from the context menu.
• Tap or click the Compatibility tab.
• Checkmark the Run this program in compatibility mode option.
• Tap or click the drop-down box and select a previous operating system.
• Tap or click OK.

You can now install the driver on the system, and you can run the Program Compatibility Troubleshooter to resolve any driver compatibility issue.

2] Delete the xhunter1.sys file

The xunter1.sys is a third-party driver file associated with software named XIGNCODE3 System Guardian or XIGNCODE by Wellbia.com. The driver file comes installed with some games, but as reported by some affected gamers, you may not have any of the games installed on your device – but the file is still present on your system and that’s because it’s a virtual driver and an anti-cheat engine/program for online games. So, if you don’t play any online games that use the driver file, you can delete the file. The file will be automatically installed when you play any online game that requires the file.

You can delete the xhunter1.sys file using Driver Store Explorer, or you can boot your system into Safe Mode and then delete the driver file in that system state.

3] Temporarily disable Driver Signature Enforcement and/or Memory Integrity

When your computer crashes and throws the error in focus if you check Event Viewer, you may see the following logged event:

Information (Event ID: 26):
The description for Event ID 26 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:
\??\C:\WINDOWS\xhunter1.sys failed to load

The message resource is present, but the message was not found in the message table.

Error (Event ID: 7000):
The xhunter1 service failed to start due to the following error:

Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

So, you can check with the driver developer to obtain and install a digitally signed driver. Otherwise, as a workaround, you can temporarily disable Driver Signature Enforcement before you launch the game that’s calling this unsigned driver file; and keep the driver signature verification disabled for the duration of the gameplay. After the session, you can enable Driver Signature Enforcement since its primary function is to ensure that only drivers that have been sent to Microsoft for signing will load into the Windows kernel during the boot process – this prevents malware/virus from creeping in and infecting the Windows kernel.

Similarly, you can turn off Memory integrity before and during your gaming session on your Windows 11/10 computer.

4] Disable Paging File

A page file (also known as a paging file or swap file) is an optional, hidden system file on a hard disk. This is a reserved portion of a hard disk that is used as an extension of random-access memory RAM for data in RAM that hasn’t been used recently.

To disable the paging file, do the following:

• Press the Windows key + R to invoke the Run dialog.
• In the Run dialog box, type sysdm.cpl and hit Enter to open System Properties.
• In System Properties, click the Advanced tab.
• Next, click the Settings button in the Performance section.
• In Performance Options, click the Advanced tab.
• Next, select the Change button under the Virtual memory section.
• Now, uncheck the Automatically manage paging file size for all drives option.
• Next, select your system drive if you have more than one drive.
• Now, select the radio button for the No paging file option.
• Click the Set button.
• Click Yes on the prompt to confirm.
• Click the OK button to close the window.
• Restart Windows.

The page file is what helps keep your computer stable. Although you may think there is enough memory in your computer to handle all the programs it runs, you can still exceed that limit, which may cause program errors and system crashes. In this case, you will have to increase the paging file size instead.

5] Troubleshoot using WinDbg

The Windows Debugger (WinDbg) is a free tool and can be used to debug kernel-mode and user-mode code, analyze crash dumps, and examine the CPU registers while the code executes. Using the tool requires a certain level of technical expertise. You can refer to the guide on how to use Windbg to troubleshoot Blue Screen stop errors and see if that helps you.

6] Reinstall the game

You can see if uninstalling (preferably, using Uninstaller Software) and reinstalling the game on your gaming rig works for you too in resolving the issue at hand. If not, you can proceed with the next solution.

I hope this post helps you!
