GPU 100% DWM....

Hello all,

 

On a MSI Modern laptop since a few weeks I have the infamous GPU at 100% with DWM.exe

I tried all the usual tricks, latest driver, latest windows update and so on, of course it was working before and all of a sudden it was not working anymore without doing anything special, maybe there was a windows update or maybe there was a graphics driver update but nothing that I can remember

Here's a copy of the intel system report result in case it helps.

What can I try to solve this ?

Thanks for the help.

Have you tried downloading and installing the graphics driver from MSI? it may be customized which may work better on your system...

You should be able to find the driver on msi website using your laptop model...

Hello and thanks for the reply

 

I've been playing with all drivers and nothing works but I've narrowed down the problem....

So latest intel driver (31 something) does nothing, MSI latest driver (26 something) does nothing, MS original driver (10 something) does nothing, all done with a driver removal before then a full install and so on....

however I have found that when watching a video flux (mpeg4) if it is encoded with the new LAV encoder it stutters and freezes and the GPU is at 100%, if I watch the same flux (some tv channel with football) and it is decoded with the old MS DVD DTV coded it works (but the picture quality sucks) with the GPU at 2-3%

 

It still freezes randomly on chrome while doing nothing specific, but the video flux I can reproduce all the time

 

So the question is how do I determine what difference in the GPU usage between this and that coded to narrow down the issues ?

Is there a way to COMPLETELY deactivate 3D from this GPU ? It is not going to be used as a gaming laptop and the most video intensive request will be to watch the occasional movie (VLC freezes a lot) and never play on it ?

 

Thanks

I have the exact same issue on my MSI.  My NVIDEA has 0% GPU and my Intel HD 100%.  I just deleted the Intel device in my device manager for now ...

If you find what caused it let us know, I had weeks of trying this and that with the help of intel support (very reactive I must say, they tried everything) and ended up resetting windows.

 

Works like a charm since then so for me it was probably a Windows Update that killed it because I didn't really do anything exotic on this machine.....
