KMODE_EXCEPTION_NOT_HANDLED seems to be connected primarily to a third-party driver, e1d65x64.sys associated with the Intel(R) Gigabit adapter, NIC/Wired network NDIS (Network Driver Interface Specification) 6.x driver. Error is known to produce the dreaded blue screen of death or BSOD. Most usually error is connected with gaming on Windows 10 computer and it manifests itself during gaming sessions. If you are unlucky and you are faced with this unfortunate error we will be happy to try to help you and present with tips and tricks in order for you to find a solution for it. Before you proceed with the provided solutions, be sure you have sufficient disk space on the Windows drive, run Disk Cleanup and then run CHKDSK.

1) Run the Blue Screen Online Troubleshooter

Open Control Panel, change the view setting to icons. Click Troubleshooting, and click “View all” in the tasks pane. Click “Blue Screen”. This opens the Blue Screen Troubleshooter.

2) Run Driver Verifier

1. Start a Command Prompt window by selecting Run as an administrator, and type verifier to open Driver Verifier Manager.
2. Select Create standard settings (the default task), and select Next. You can also choose to Create custom settings to select from predefined settings, or to select individual options. For more information, see Driver Verifier options and rule classes and Selecting Driver Verifier Options.
3. Under Select what drivers to verify, choose one of the selection schemes described in the following table.

   Driver verifier table:

   Option	Recommended use
   Automatically select unsigned drivers	Useful for testing on computers that are running versions of Windows that do not require signed drivers.
   Automatically select drivers built for older versions of Windows	Useful for testing driver compatibility with newer versions of Windows.
   Automatically select all drivers installed on this computer	Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system. This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance.
   Select driver names from a list	In most cases, you will want to specify which drivers to test. Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance because an I/O request packet (IRP) is passed between each of the drivers in the stack, which allows for a greater level of detail to be provided when an error is detected. Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues (such as deadlocks or mutexes). The Special Pool and I/O Verification options are more effective when used on one driver at a time.

4. If you chose Select driver names from a list, select Next, and then select one or more specific drivers.
5. Select Finish, and then restart the computer.

3) Update network device drivers

Go to the official Intel website and try to find newer versions of drivers, if there are none perhaps you will need to revert back to the previous version.

4) Scan memory for issues

Run a memory test on your system, sometimes these errors can be traced back to a faulty RAM bank.

5) Stop over-clocking your PC

If you have overclocked your PC please reverse it back to its original state and see if that would solve the issue

6) Perform System Restore to the previous restore point

If none of the previous solutions have bared fruit, roll back to a previous restore point and that should solve the issue.

As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.
• Navigate to the option “Control the mouse with keyboard” and then uncheck the “Turn On Mouse Keys” option to turn off the Mouse key.
• Click on Apply and then on OK to save the changes made.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections
