RefreshRateService PowerEvent Error – System.ArgumentNullException (G513QY)

memocaan
Level 8

Hi everyone,

I'm experiencing an error related to the RefreshRateService on my ASUS ROG Strix G15 Advantage Edition (G513QY). Every time I boot the system or resume from sleep, I see the following error in Windows Event Viewer:

Event ID: 0
Source: RefreshRateService
Error:
System.ArgumentNullException: Value cannot be null. Parameter name: name
at Microsoft.Win32.RegistryKey.ValidateKeyName(String name)
at Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable)
at MonitorRefreshRateService.MonitorRefreshRateService.GetRefreshRate()
...

- BIOS is up to date.
- RefreshRateService version is 2.1.0 (latest from ASUS support site).
- Armoury Crate is updated.

The error doesn’t cause visible problems but keeps logging every time. Is there a fix or known workaround for this?

Thanks in advance.
