dwm.exe (Desktop Window Manager) using high cpu, spikes and unknown issue

post #1 of 4
Thread Starter 
Hello everyone,

I've had this issue for awhile, tried to do a clean install, I notice a higher CPU usage after I install the graphics drivers.

I'm using an R9 290 triX, installed the 14.2 drivers, same thing, 14.1, same, don't really want to do below but will do if needed, gonna try it.

I've google it for the past 4 hours, some people saying logitech software(not using any im on a clean install) and I see this thing using 15-20% cpu when I'm idle for no reason, making my CPU heat up more and it annoys me.

I'm running on a windows 8.1 pro, I got the basic drivers installed and now I cant figure this thing out..

Anyone could have an idea?

Have you tried an older version of the driver to see if it does the same? Or conversely tried a beta driver?

If you want to approach it from the windows side launch a command prompt and type in SFC /scannow. This will run a system file check that verifies the integrity of all windows system files and replace any that have issues.

EDIT: One other thing, do you have any desktop interface applications like rocketdock or fences or anything like that?

Hey man,

somehow, I've stood back and thought about it. I have 3 displays connected to my PC, my TV (720p), and two other monitors. I've thought about it like this : Maybe the fact that my TV doesn't upscale to 1080p and my stuff is in 1080p except this isn't working out well together.

Guess what..

It's only going maximum to 1-2%, but I don't have my TV plugged in my PC anymore. Guess it's a good reason to get a 3rd monitor!

Glad to hear its resolved and that's definitely a good reason to get another monitor thumb.gif
