GPU spikes?

[Mooshy6665]

I'm running 64 bit windows 10 on a asus g551jw laptop. 

 

I Opened up afterburner because I was about to launch a game, my computer runs pretty hot, so I like to keep an eye on it. Normally the GPU will spike once when I launch afterburner, then stay at zero if I don't having anything running. Today, for some reason.... its just spiking up and down constantly. I have reset the computer, uninstalled and reinstalled the drivers for the GPU, I even download GPU-z to make sure that it was not an afterburner error, and they are showing the same. It will even out every once in awhile, either at the spiked temp of around 40, or at 0, but starts backup again after awhile.  I've run out of ideas, and done all of the trouble shooting that I can think of. 

 

 

Any ideas?

When have you last cleaned it maybe some dust build up in the laptop

I think that your laptop is constantly switching between the integrated and dedicated GPU: it's the only thing I know that could explain the 0°C temperature.

I don't know why it would do that though.

I can toggle between the integrated GPU and the dedicated one on afterburner, and GPU-z. The integrated GPU shows no activity at all.

switching back and forth between the dedicated and integrated GPS repeatedly does cause the same spikes..... could there be something constantly engaging, and disengaging my GPU?

So there are only spikes from the 960m? Nothing at all from the integrated GPU?

[Mooshy6665]

Correct, nothing from the integrated GPU.

Do you get these spikes when you game as well?

It held steady for awhile when I had the game sitting on the main menu, then started spiking again. Once I actually started playing the game, the temp went up to around 50 and stayed there like it should. And once I exited the game it went down to zero and has stayed there since. Is there away to tell what process are using my GPU at any given time?

I found this one: http://www.geeks3d.com/20160824/gpu-shark-0-9-10-released/

If you go into view -> detailed mode you can see which processes are using your graphics card.

 

I'm starting to think that it could be a sensor malfunction, although it is a strange one.

GPU shark didn't show anything that shouldn't be running. I've been disabling the GPU when i'm not gaming, and so far that's been fine.
