Quick Solution Guide to Error Code 40

Error Code 40 – What is it?

Error Code 40 is a device driver error that users encounter on any Windows 2000 and later operating systems. It occurs when the peripheral device that you connect to your PC cannot be accessed due to a change in the system registry.

This is due to the presence of invalid sub-keys of the device driver in the system registry.
It is a common error that users come across and appears on your PC with either of the following messages:

“Information in the registry entry for this driver is invalid”

OR

"Windows cannot access this hardware because its service key information in the registry is missing or recorded incorrectly. (Code 40)"

Solution

As mentioned above, the error code is triggered when the device driver’s invalid sub-keys appear in the registry, effectively changing it. This happens when the windows system files get damaged due to the following factors:

  • An incomplete program uninstallation
  • An incomplete program installation
  • Hardware is not removed properly
  • System recovery from viruses
  • An improper system shut down

Factors such as incomplete installations or uninstallations or an improper system shut down can cause files to become damaged that threaten the health of your computer.

Removing viruses from the computer is also another factor as it removes the entries in the Windows system files which contain the viruses including spyware or malware

Further Information and Manual Repair

Fixing Error Code 40 is similar to fixing other device manager error codes. Here are a few methods you can try.

Method 1 – Use System Restore

You can use system restore to eliminate the problem. Here is how you can use it:

  • Log in using an Administrator account
  • Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
  • Click ‘Restore my computer to an earlier time’ and click ‘Next’
  • Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
  • Click ‘Next’ on the confirmation window to proceed
  • Restart your PC after restoration is complete

By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system registry files that can help avert the error code.

Method 2 – Manually uninstall then reinstall the device driver

If using system restore also does not work in removing the error code, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.

This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what contributes to the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.

You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC. Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’.

Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 3 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick, however, it may be time-consuming especially when you would have to resort to your hardware user manual.

Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

It further ensures that your drivers are installed in their entirety leaving no room for any incomplete files to remain that create Error Code 40.

It also has the added advantage of being able to backup and restores your files should there be the slightest possibility of system file damage.

Thus, registry damage can be averted by letting the software roll back the system files to an earlier healthy checkpoint. Driver Assist is the answer to fixing your PC error codes accurately and quickly.

If you are unable to access or see edges of your desktop on the TV screen it is very likely that overscan is the issue. In order to fix this be sure to select HDTV's aspect ratio to fit the screen setting in the picture setting. Sadly finding this option on your TV will be different from manufacturer to manufacturer and even from model to model of the same manufacturer so we can not cover all models but in most cases option is located under picture settings or advanced options. Sometimes you will face even different overscan settings instead of classic ft to screen options, in this case, experiment with the setting until you find one which will work. If you have it, find settings in the user manual of your TV. Luckily you have managed to find the proper option on your TV set and have chosen the right aspect ratio for display. If everything works ok there is no need for the next step but if you experience a different resolution than desired on your TV follow this next guide on how to change the resolution of the TV on your PC.
  1. Press the ⊞ Windows and type Change Display Settings. Click on the top result.
  2. Once the Display Settings App opens, you’ll see two screens (or more if you’ve got multiple HDMI outputs connected). Make sure you select the right display for the HDMI TV before making any changes. You can do this by clicking on Identify.
  3. You’ll see the number from the screenshot above displayed on the monitors for a brief period. Depending on which screen is set to your primary display, make sure you change the settings for the HDMI monitor.
  4. Select the HDMI monitor from the available displays.
  5. Scroll down until you see the current resolution settings for your HDMI monitor.
  6. You can change the resolution settings and test different values that match your HDMI TV’s configuration.
  7. Once you change the setting, Windows will apply the new resolution for a limited time and revert if you don’t accept the new setting.

Merge or Delete an OEM Partition in Windows
OEM Partition, also known as System Reserved Partition, is placed by the OEM to help users recover their computers or bring back the original state of the computer when it was bought. If you’ve observed that a part of your hard drive says “Healthy (OEM partition)” in the Disk Management and it occupies space in GBs, then this means that it’s normal and there’s nothing to worry about except that part of the storage space is not available and even when you right-click on it, the only thing it displays is the Help menu. Thus, in this guide, you will be guided on how you can merge as well as delete an OEM partition in your Windows 10 computer. Since the Disk Management tool in Windows won’t let you merge or delete the OEM partition, you can just use the built-in command-line tool known as Diskpart. Note that you have to be extra careful when you run the commands as it could mess your computer up and before you proceed with the instructions provided below, make sure that you create a System Restore point first. Once you have that covered, follow the instructions below. Step 1: Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and tap Enter to open the Command Prompt. Step 2: Next, execute this command to launch the Diskpart tool: diskpart Step 3: Execute this second command to view the list of the disks in your computer: list disk Step 4: Now select the disk you want to manage by executing this command: select disk x Note: In the command above, replace “x” with the letter of your disk. Step 5: After that, execute this command to display all the volumes or partitions: list partition Step 6: Now execute this command to select the partition you want to delete: select partition x Note: You have to replace “x” with the partition you want to delete. Step 7: Once done, execute this command to delete the selected partition: delete partition override Step 8: Afterwards, execute this command to merge the OEM partition with the adjoining value: Extend Note: if you only want to merge part of the partition, you need to use this command “extend [size=<size>]”. For instance, you want to extend its size by 5GB, then you need to type “Extend size=5000”. The size you set is the size you select from the OEM partition. This will extend the selected volume by size in MB or megabytes.

Selected boot image did not authenticate Error
If you are using UEFI and you encountered an error message that says, “Selected boot image did not authenticate”, then read on as this post will show you what to do it fix it. This kind of error indicates that UEFI is having an issue in figuring out if the boot image has tampered with. UEFI offers Secure Boot and if the boot image seems to be invalid, you won’t be allowed to boot into your computer. Aside from that, it could be that you may be using endpoint encryption and the software can’t validate the certificate. To fix the “Selected boot image did not authenticate” error in UEFI, you need to first check if the error has given any reference to any software that you might have for encryption. If it has, then you need to disable the Encryption tool to resolve the problem. In addition, you could also try to disable Secure Boot or perform Startup Repair in case the disabling Encryption tool didn’t work. For more details, make sure to use each one of the options provided below as a reference.

Option 1 – Try to disable the Encryption tool

The first thing you can do to fix the “Selected boot image did not authenticate” error is to disable the Encryption tool. Many users reported that some encryption tools like the ESET Endpoint Encryption won’t let them boot into the computer if the system manufacturer does not include the correct certifications as a part of the UEFI BIOS. And since there is no way to bypass this, you have to disable Secure Boot in order for you to boot into your computer.

Option 2 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the error. To disable Secure Boot, here’s what you have to do:
  • First, boot your computer into Windows 10.
  • Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
  • After that, go to the BIOS of your computer.
  • Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
  • Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Select the UEFI Firmware Settings which will take you to the BIOS.
  • From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
  • Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
  • Save the changes made and exit. Afterward, your computer will reboot.

Option 3 – Try to run the Automatic Repair Utility

If disabling Secure Boot did not fix the problem, you might also want to run the Automatic Repair utility in fixing the error. To do so, follow the steps below.
  • You can start by booting into the Advanced Recovery Mode.
  • After that, select Troubleshoot > Startup Repair.
  • Next, follow the on-screen instructions that appear on the screen and finish the Automatic Repair process.
  • Now check if the block is gone once the reboot is completed.
