I've posted this elsewhere but gotten no replies so here goes nothing.


I recently upgraded from one GTX 970 to two of them with SLI. Now, occasionally my screen will go dark for around 10 seconds. This never happened prior to the upgrade.

This generally occurs with a GPU load from vds.exe. Usually temperatures are fairly high when this happens (70 C), but after leaving my fans at 100% manually, this happened at only around 50 C.

It has also occurred when my displays first turned on after a long period of inactivity (normally they come on within 2 seconds, but now they seem to flicker a bit between grey and complete darkness for 10 seconds before coming on, just like what happens while I'm using my PC.)

This also seems to always happen when I watch videos and it only occurs when SLI is enabled.

Stuff I've tried: Upgrading to latest BIOS, DDU and clean install of latest GPU drivers, reinstall of windows.

Some statistics:

GPU 100% spike is due to firefox.exe (this is where the GPU hit around 70 C) and the 40% usage is due to vds.exe.



System specs:

GPU: GTX 970 (2x, SLI)

CPU: i5 4690K, not overclocked

Motherboard: Z97-G45, BIOS version 2.9

RAM: G.SKILL, 4x 4GB sticks, no overclock

PSU: Rosewill 750W Gold Certified

Operating System & Version: Windows 10 x64 from upgrade, version 1607 (OS build 14393.969)

GPU Drivers: GeForce 382.33 (latest), clean install

Monitors: 2 ASUS 1920x1080 monitors, perfectly working, both plugged into one card.

Get a new setup of windows. You need to whipe out your drivers from registry. Before you do it try this program to uninstall the drivers and then install the latest ones from nvidia website : http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

You need to use ddu. This whipes all the files from previous driver versions from registry. It might be a metter of monitor as well. I would also try to connect via all the outputs from the card to the monitor. 70 degrees is a very good temperature. Even 80C is safe. Hope I helped! :)

I thought reinstalling windows fixed it but nope, issue persists. There doesn't seem to be any correlation with the card outputs or anything as well. DDU did nothing to solve this either.

Afterburner is already set up to handle temperatures just fine. I don't think the cards have ever passed 80 C.
