GPU usage at 100% (without gaming)

[antobanano]

Hi,

since a couple of months, my gpu usage is going nuts randomly and it's very frustrating because everything become very slow ...

It happens mostly when I'm in a zoom meeting but also when I'm watching a youtube video.

I have tried to uninstall both of my graphic card's driver with DDU, tried to run zoom using NVIDIA graphics card, scan my computer with ccleaner, keep up to date my system, but nothing seems to work.

In the task manager, Desktop Window Manager is using to much GPU (see pictures below) and I tried to change how windows handle graphics on my computer but it didn't work either. There is also "Windows Driver Foundation - User-moded Driver Framework Host Process" thats using 10 to 20% of GPU usage sometimes.

 

Here are my specs

Inspiron 15 7559
Processor    Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz   2.60 GHz
Installed RAM    16,0 GB (15,9 GB usable)
System type    64-bit operating system, x64-based processor, Windows 10
Pen and touch    Touch support with 10 touch points

GPU 1     Intel(R) HD Graphics 530

GPU 2     NVIDIA GeForce GTX 960M

I also have to 2 monitors attached to my laptop, unplugging them doesn't seem to solve the problem and all the drivers for them are up to date (for the usb dongle)

 

I started to wonder if there wouldn't be a virus who use my gpu power to mine some bitcoins

There is a thread (and a possible answer) on the Microsoft forums here:
