I can no longer play WoW because my monitor goes into power save mode. It just started happening last week. I used to be able to play for a little while before it happened, but the last two times I’ve tried to log in, it happened within 30 seconds. I built my PC in 2017, but I updated the power supply a year ago and the GPU in June. I have tried:
Going down to one monitor from two
Using a completely different monitor
Scan and repair of WoW
Running diagnostics on my pc
Changing pc power settings to High Performance
Changing from DirectX12 to DirectX11
New HDMI cord
Different HDMI port
Checking my system settings with WoW open - no overheating of GPU
I played Dragon Age: Inquisition for over an hour and it didn’t happen
Specs:
Windows 10
Intel Core i5-7600K
G.SKILL Ripjaws V Series 16GB DDR4
Crucial P2 1TB 3D NAND NVMe PCIe M.2 SSD Corsair RMX Series (2021), RM750x, 750 Watt
NVIDIA GeForce RTX 3060 12GB GDDR6 PCI Express 4.0
This sounds like the GPU is hanging or crashing, which is causing the monitor to lose signal and go into power saving mode. GPU issues like this can happen for several different reasons, including unstable clocks on the GPU, hardware problems, or power supply issues. In some cases it can be due to a driver problem or conflict with other software on the PC.
If you haven’t already I’d recommend doing a clean reinstall of the Nvidia drivers:
Click on the first link under “Announcements” titled Display Driver Uninstaller (DDU). Then click the “Official Download Here” link to start the download.
Run the .exe file and extract the contents to the default location. Open the new folder and run the Display Driver Uninstaller.
You will get a pop-up saying it is recommended to reboot in Safe Mode, feel free to ignore this if you are not familiar with how to get into Safe Mode. To start the removal process, click on the driver type on the right side first, then click “Clean and restart”
Run the driver installer and use the default/recommended install steps.
You can also try using Nvidia Debug Mode which should remove any factory overclocking on the GPU and return it to its stock clock speeds.
If these steps don’t help you may need to contact the GPU manufacturer so they can try to diagnose it further, and maybe test with some GPU benchmarks / stress tests. It very well could be a hardware issue that happened over time or after installing the new GPU.
