Windows 10: "system" ntoskrnl uses GPU 1-copy every few seconds

Hi, I found "system"ntoskrnl uses my GPU every few seconds and it reduces the battery life. Even if I set the GPU as integrated from the Nvidia control panel, "system" ntoskrnl keeps using Nvidia GPU every few seconds. Task manager doesn't show any GPU usage in performance but hwinfo64 reports some. How can I fix it?

:)

Hi,

To help you with your concern, we suggest you to try running a Windows System File Checker with the following steps:

• Click Start.
• Type command in the search box.
• Press Control + Shift + Enter
  button on your keyboard.
• Enter your credentials on the permission dialog box, then click Yes.
• A black box will open with a blinking cursor.
• Enter sfc /scannow.
• Wait for the System File Checker to scan for msvcp_win.dll. System scan may take a while.
• Follow the on-screen commands.

We also suggest a clean boot in Windows. You can refer to this
link for steps.

Let us know how it goes.

Thank you.

 

B(lack)SOD after closing GPU demanding applications and games

I would like to suggest 2 more things if you don't mind,
1. Seat the GPU in another slot, if possible, and see if that helps anything
2. Use the GPU in another system, if possible, this is a step to determine that it is really the GPU and not multiple defective slots or something else from the system.

 

Is there a way to force a program to use a secondary GPU?

Hi Zeond1987,

Thank you for posting your question in the Microsoft Community.

Are you getting any error message?

If you have a multi-GPU system running Windows 10, you can now manually specify the preferred graphics processor an app should use for performance or to improve battery life.

In order to force an app to use a discrete GPU instead of the integrated one, or vice versa to provide better system performance or battery life, I suggest you to follow the below steps.

1. Open Settings, and click/tap on the System icon. Click on System.

2. Click on Display on the left side

3. Under “Multiple displays,” click the Advanced graphics settings link.

4. Select the kind of app you want to configured using the drop-down menu:

Classic app — these are your traditional Win32 desktop programs.

Universal app — these are those app available through the Microsoft Store.

5. If you select Classic app, you’ll need to click the Browse button to locate the “.exe” file to add the app. Otherwise, if you select the Universal app option, you’ll see a second drop-down menu to select the app.

6. Select the app you added from the list.

7. Click the Options button

8. Set the graphics preference you want to use:

System default — this is always the default setting, and Windows 10 decide which GPU to use automatically.

Power saving — runs the application on the GPU that uses the least power, which most of the time is your integrated graphics processor.

High performance — runs the application on the most capable GPU, which is most of the time an external or discrete graphics processor.

9. Click the Save button.

I also recommend you to update the GTX 1080 drivers from the manufacturer website, and
Check if that work.

Hope it helps,
