Error messages can be a headache and can affect your productivity. But the good thing is that there is a way to fix them. And in this article, we’ll show you what to do with one system error that may appear on Windows devices: KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) BSOD error.

What Is KMODE EXCEPTION NOT HANDLED (e1d65x64.sys)?

The KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) BSOD is an error that may occur on Windows devices. It is triggered by different things, such as a problematic Windows driver, a system error, and an improper configuration of a device.

When the system kernel detects the presence of an incorrectly configured peripheral, receives memory access requests that do not meet hardware specifications, or comes across instructions that cannot be executed, this error message is reported. And then, Windows will request for a quick restart. What makes this quite frustrating and annoying is that this goes on endlessly.

But what causes this error in the first place?

What Causes KMODE EXCEPTION NOT HANDLED (e1d65x64.sys)?

As mentioned above, there are many possible factors that may trigger this error. And most of the time, the solutions are dependent on the cause. Therefore, it is vital that you understand the cause in detail to make it easier to diagnose the problem and resolve it.

Here are the common causes of the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) error:

  • A problematic RAM module – The RAM is responsible for all the read and write processes in your system. If it is faulty, then it can affect your system’s health and trigger error messages to appear, such as the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys).
  • A corrupt or incomplete installation of a program – When you install a program or application in your computer, a new registry entry is generated. Using this registry entry, Windows can track the programs installed in your system. When you delete the program, this registry entry is updated to inform Windows that the program is no longer there. Now, when the uninstallation of the program is incomplete, error messages may occur. To avoid this instance, experts suggest running a PC repair tool. With such a tool, your system registry will be free of errors.
  • Malware entities and virusesMalware entities and viruses can sometimes interfere with your system processes. They may even affect the way Windows executes processes and operations. If this happens, system files may be corrupted or important registry entries may be deleted, which can then result in the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) error. To keep these malicious components at bay, it is best that you keep an antivirus program running in the background for real-time protection.
  • Improper system shutdown – When a computer is active, there are plenty of processes running in the background, some of which are vital in the smooth running of Windows. If you abruptly shut down your computer, it is possible that system instructions will be affected, a situation that can result in the corruption of system files and the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) error.
  • Missing, Corrupt, or Outdated device drivers – Device drivers are essential in the Windows environment as they enable communication between software and hardware components. When they go missing or if they are incorrectly configured, they can cause your system to misbehave and throw random error messages such as the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) error. To ensure your device drivers are up to date, use a Driver Updater tool.

How to Fix KMODE EXCEPTION NOT HANDLED (e1d65x64.sys)?

Take note though, you need to boot into Safe Mode or use an installation media to perform the solutions below. Also, you need to check your available disk space to rule out the possibility that the problem is caused by an insufficient disk drive space.

Solution #1: Use the Windows BSOD troubleshooter

In this solution, you will use the Windows BSOD troubleshooter, a utility created by Microsoft to fix BSOD errors. When used, the troubleshooter will ask you when the error surfaced and how it experienced the BSOD. You will be presented with three options (While upgrading on Windows 10, After an update was installed, or While using my PC) and you need to choose one. After making a choice, more instructions will be given to you. Just follow them and the BSOD error should be fixed.

Solution #2: Update your device drivers

As mentioned above, a corrupt or outdated device driver can trigger BSOD errors like the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) error. This means updating your device drivers may help if you’re dealing with BSODs. To update your device drivers, follow these steps:

  1. Into the search field, input device manager and click on the most relevant search result.
  2. Choose a category to see names of devices currently installed on your computer. Right-click on the device that you want to update.
  3. In the next window, click the Search automatically for updated driver software option.
  4. Hit the Update Driver button. Wait as Windows tries to find an update for the device. If it does not find any, manually visit the device manufacturer’s website and download the update from there.

Because updating device drivers can be risky, we recommend using a driver updater tool instead. This will prevent any driver compatibility problems that may arise if you install an incompatible driver version.

Solution #3: Fix your problematic RAM

If you suspect that your RAM is to blame for the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) error, then use the in-built Windows Memory Diagnostic tool to identify any RAM-related errors. To use the tool, refer to the steps below:

  1. Launch Command Prompt by pressing the Windows + R keys.
  2. Into the command line, input mdsched.exe and hit Enter.
  3. A new window with several options will now show. Select Restart now and check for problems.
  4. At this point, Windows will perform a memory check. Don’t panic if you see a blue screen. It’s part of the process.
  5. Once the check is complete, read the results. If it says that your computer is experiencing problems with your RAM, then replace it with a new one.

Solution #4: Get rid of malware entities and viruses

Malware entities and viruses can cause different sorts of issues in a computer, which means they can also be the cause behind the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) BSOD error that you’re facing.

To get rid of these malicious components, always make sure that your antivirus program is up and running. Also, run a regular PC repair scan to resolve problems that these entities have left behind.

Solution #5: Perform a System Restore

If you cannot identify what’s causing the error, you may perform a System Restore. This will allow you to restore Windows to a state prior to the error. However, before doing so, make sure you have a backup of all your important files and settings. Performing a System Restore may cause you to lose any installed third-party program, system settings, and important documents.

To perform a System Restore, do the following:

  1. Press the Start button.
  2. Input control panel into the search field.
  3. Select Control Panel from the search results.
  4. Navigate to Recovery and choose Open System Restore.
  5. Hit Next.
  6. Choose a restore point prior to the occurrence of the error.
  7. Click Next, and then Finish to complete the process.

Solution #6: Reverse overclocking

Overclocking is a hack used by some advanced Windows 10 users to speed up some Windows components, such as the motherboard, graphics card, and memory. With overclocking enabled, the mentioned components may run faster. However, doing this also has a downside as it can cause BSOD errors to appear.

If you have just overclocked your PC when the error appeared, then you may have found the culprit. Sometimes, overclocking Windows can interfere with system processes and result in BSOD errors like the KMODE EXCEPTION NOT HANDLED (e1d65x64.sys) error. In this case, reversing this setting would help.

To reverse overclocking, do the following:

  1. Enter the CMOS and BIOS settings.
  2. Check the voltage settings of your devices and make sure they’re set to normal.
