Solution 1Recommended

Uninstall Conflicting Motherboard Utilities

Remove third-party motherboard add-on software like MSI Dragon Center or Nahimic, which are known to cause system conflicts with Excel on newly built PCs.

Many newly built computers include bundled motherboard software for system management and audio enhancement. Certain utilities, specifically MSI Dragon Center and the Nahimic audio program, can hook into system processes and conflict directly with Excel's rendering engine, causing massive slowdowns.

1
Open Windows Settings

Press the Windows key + I on your keyboard to open the Windows Settings app, then navigate to the 'Apps' section.

2
Locate Conflicting Software

In the 'Apps & features' menu, use the search bar to look for 'MSI Dragon Center', 'Nahimic', or other proprietary motherboard add-on software.

3
Uninstall the Application

Click on the software name, select 'Uninstall', and follow the on-screen prompts to completely remove the application from your computer.

4
Restart Your PC

Reboot your Windows 10 computer to ensure all background processes and services related to the uninstalled software are fully terminated. After rebooting, open Excel to verify if the performance is restored.

Frequently Asked Questions

Why does only Excel run slowly while Word and PowerPoint are fine?

Excel relies heavily on specific hardware acceleration and system resources for rendering complex grids and calculations. Motherboard utilities that manage graphic overlays or audio processing often hook into these same display pipelines, uniquely disrupting Excel's user interface performance without affecting Word or PowerPoint.

Can I reinstall my motherboard software after fixing the Excel issue?

Yes, you can try downloading and installing the most recent version of the software directly from the manufacturer's website. Developers frequently release patches to fix conflicts with widely used applications like Microsoft Office. If the lag returns after updating, you may need to keep the software uninstalled.

Does disabling hardware graphics acceleration in Excel help?

In some cases, yes. By going to Excel's menu via File > Options > Advanced and checking the box for 'Disable hardware graphics acceleration', you can force Excel to bypass the GPU rendering path that may be conflicting with the third-party motherboard software.
