High GPU usage by "csrss.exe" and "dwm.exe" even when idle.

Hi,


I have been having this problem for a very long time. I have searched on the web and many people seem to have had the same problem, but no definitive solution posted anywhere. So I open the case again:


My problem is, windows processes Client Server Runtime Process (csrss.exe) and Desktop Window Manager (dwm.exe) very often start using the integrated GPU card (GPU 0 - 3D). This causes the laptop fans to go crazy, there is stuttering on videos and on my mouse and my work (which is resource intensive) is affected.


This issue can happen at any time, at any level of use of the computer. That is, it can happen as soon as I boot up, when working, when watching netflix, etc. It is indiscriminate and over the past year I have never seen any correlation to specific usage. The frequency is very high, and when it starts it keeps going for prolonged periods of time to the extent that I would say almost half the time I am on my laptop, this issue happens.

In the past I have tried:

  • Clean install of Windows
  • Re-installing the integrated graphics card's drivers
  • Re-installing dedicated graphics card's drivers (GTX 1050)
  • Disabled all fancy Aero settings

But nothing fixed it.

Below is a screenshot of what the task manager usually shows during these episodes.

My machine:

  • Dell XPS 15 9560
  • OS: Windows 10 Home 64-bit (10.0, Build 17763)
  • Processor: Intel Core i7-7700HQ CPU @ 2.80GHz (8CPUs)
  • RAM: 16 GB
  • Integrated graphics: Intel HD Graphics 630
  • NVIDIA GeForce GTX 1050


I have seen a few threads in which this issue happens on the same machine as mine. No definitive answer as to why it happens or how to fix it.


This issue has been going on for as long as I remember having this laptop. Any help would be much appreciated.
