Artifacts not GPU related ?

Hi everyone i'm gonna need some help !
I've been dealing with random artifacts for about 2 weeks. I think it's not GPU related because it happens on 2 different GPU, one being new (a 680 and a 970).
It only happens on windows, where there is videos on the page, like on youtube or twitch. When I stop then restart my PC everything is back to normal. It doesn't happen a lot, like twice a day.
Games are fine.

here is a pic :
2c548632-05a9-46bf-9b5e-1a0bd597c7e2.jpg


Drivers : 347.25
Happens on both of my monitors.
CPU and GPU not overclocked.

Temps are normals, GPU <60°C and CPU 35°C.

The rest of my PC :
CPU : Intel i7 4790K
Motherboard : ASUS Z97-M Plus
RAM : Corsair Vengeance 2 x 4Go 1600 MHz
GPU : EVGA GTX 970 FTW or MSI GTX 680
SSD : Samsung 840 EVO 250Go
HDD : Seagate Barracuda 7200.14 2To
Power supply : LDLC QS-550+ (Seasonic)
Windows 8.1 Pro 64

I don't know where to search or what to do.
 
are you running through an adapter?

only thing i can think of is to restart the rig once. probably improper power signal being sent to the monitor, I get a Rainbow banding sometimes on my monitor when i initially start up, just takes a restart to get it right, no issues in games either
 
nVidia panel settings? Seems to be related to hardware acceleration.

Have you tried to turn off hardware acceleration on your browser and testing?

No adapter

I'll try that the next time it happens, didnt think of that. If it does something what is related to that ? Will it be a software causing these artifacts ? Also nvidia panel options are all by default.
 
Turn off any video acceleration in the nVidia Control Panel and and right-click the Youtube video and turn off hardware acceleration. Update Flash too.

Flash is up to date. It also happens with HTML5 Videos. I'm not sure how to turn off hardware acceleration though.
 
On Chrome you must go to advanced options. It's on the configuration page ( chrome://settings/ ) just below "Default Browser"
 
test it that way to see if that solves it. If it does then we can chalk it up to video acceleration. Maybe a driver change would help with that.

Did this start to happen after a driver upgrade or something? Try installing the previously working driver and test. Also report the issue to nVidia so that they can correct it on a future driver release.

Did you install a codec pack or something related to video processing? Video editors ofter install custom renderers too.

Well since it happens randomly I have to wait now :/ I'm going to try an older driver
 
first wait and see if disabling HW acceleration solves it. If we start to change variables from the get go we'd never pinpoint the cause.

If disabling HW accel works then we can look into changing drivers and see if that's the cause.

Indeed.
 
Disabling HW acceleration in Flash can help, but from what I have read it mainly affects AMD systems.
 
Ok I'm back with some update. I had artifacts 20min ago and did some tests :
To sums things up :

- Drivers are still the same for now, 347.25
- Firefox with hardware acceleration : Artifacts.
- Chrome without hardware acceleration : no problem.

I also installed a fresh new VM (ubuntu on it) with VMware player :
with hardware acceleration : artifacts everywhere
without it : no problem.

Here is where it's a bit strange. Since I have two monitors I did some others tests. I was playing a youtube video (whish had artifacts) on my firefox and launched a game fullscreen on my second monitor and my artifacts completly disappeared ! Then I alt-tabbed, they were back again. Went back to the game, gone. I also tested an other game with windowed fullscreen but it obviously did nothing.

Then I rebooted after all my tests and they were gone. What to do/test now ?
 
turn off hardware acceleration in Firefox, its been bugged since release, it doesnt put enough load on the GPU to run it at its recommended clock rate/voltage.

Yes but that doesn't help me at all with my problem, I mean if I want to use a VM, I can't use hardware acceleration because of this artifacts problem.

not the same kind of hardware accleration ...

there is a setting in firefox itself called hardware acceleration, Turn it off, you're not turning off hardware accel to the GPU itself just the capability of Firefox to use the hardware. so basically it relies on the CPU only.

You need to manually boost the clock rate and the voltage to nominal levels when using VM software.

I appreciate, but how to fix the other problem then ?
 
read my last line on my previous post

Ok I think I understand, since when I'm in game, the GPU use its 3d profile and that seems to solve the problem. But isn't it strange that it happens on two different GPU and only on my PC ? Is there something more convenient that could fix it for good ? Also why is it random, it happens like 2 time a day
 
only thing i could think of is os issue, but the problem of artifacting has occurred since the idea of power savings mode for GPUs when in 2D states.

He has an Intel/nVidia system.



Since the issue seems to be related to 2D clocks a workaround would be to install MSI Afterburner and make a custom 2D profile.

Say, how are your power options setup? Frankly I don't mess with them much so I don't know if there's a setting that would affect HW acceleration.

Also, try older known working drivers.

I currently have EVGA Precision. What eidairaman1 said make perfect sens because when I use VMware player with HW acceleration my GPU still use its 2d profile so I guess we know where the problem is now.
So I have either to rollback to an old driver or make a custom profile, right ?

Also thank you for helping me, I would have never guess the problem was related to that
