I have lost the file:
"C:\Program Files (x86)\ASUS\Splendid\Backbone.exe"
It seems that this file has something to do with the ACMON error.
How to restore it?
If you don't have the setup package then you can use the recovery option to restore your laptop to its original state. Alternatively, you can download the setup package and perform re-installation which will fix this error you're having.
