Hello,

 

Recently my system is getting slowed down by a process called "System". This processes CPU usage ranges from 15% to 40%:

Using a guide from superuser.com I analyzed this process using Windows Performance Analyzer. It seems the high CPU usage comes from amdkmdag.sys:

Therefore I updated my graphics drivers (Intel & AMD) and the problem was gone at first. However, the next day the problem reappeared. Then I updated my drivers using HP SoftPaq Download Manager but that also didn't fix the problem. Then I uninstalled all graphics drivers and downloaded and installed the drivers from the HP support site, which didn't help either.

 

Has anyone an idea how to fix that?

 

PS: I also use a HP USB-C universal dock with a second screen connected to it by DisplayPort. I also reinstalled the drivers for the dock. However, the process still has a high CPU usage, when the notebook is not connected to the dock. Therefore I don't think the problem is related to the dock.
