Hi LTT forum!
OS:Win10
CPU:4930k (stock)
RAM:16GB (dual channel unfortunately)
Mobo:Asus P9X79 Pro
GPU: Asus Strix 1080 ti (stock)
SSD: 1TB Kingston
PSU: 850W BeQuiet
Monitor 1: Benq Zowie XL250-B
Monitor 2,3: Benq Zowie XL2430
All but monitors, SSD, GPU are almost 7 years old.
Monitor 1 is hooked up with Display Port and runs 240hz fine.
Monitor 2 is also using DisplayPost and runs its 144hz fine.
Monitor 3 is only using an old HDMI cable atm so is limited to 60hz which for now works.
My issue is when even playing World of Warcraft Classic my main monitor will go blank for 3-4 seconds.
This is easily repeatable using Furmark. "Preset:1080" and will cause multiple black screens for the same 3-4 seconds.
I just ran the test. Fan speed 34%. First Black Screen 1/4 the way through at 62 degrees C. Temp levelled out at 65. 5 total black screen occurrences.
Since having this issue I've had one occasion where all the fans not spinning on the GPU. The card still ran but I noticed instability and I quickly adjusted the fan curve in MSI Afterburner. I imagine this is the most likely cause of my issue. But its interesting this happened after the initial symptoms.
When unplugging one of the monitors to only use 2 monitors, there is no blank screen when running Furmark.
When I test again with my other DVI-D 1440p monitor it still goes blank at 3 monitors.
What I've tried so far:
Different configuration of monitors. Setting other monitors as Primary Monitor in Nvidia Control Panel
Lowering the Refresh Rates of all monitors
Unplugging all unnecessary internal drives and external connections
Updating drivers with a clean update via Geforce Experience custom install option
I reinstalled Windows a few weeks ago due to this issue and that didn't fix it
I originally upgraded my monitors because I was having the same issue with the same 240hz main monitor, a 60hz 1400p DVI-D second and a Display Port to DVI-D 1080p TV. Hoping that the conversion cable from DP to DVI was causing it or something. The only constant is the PC and the 240hz monitor.
I understand the Furmark is putting stress on the GPU but playing WOW Classic on the (Classic) old school graphics settings still triggers the Blank Screen in busy environments.
I've searched on and off for months and I don't have any new ideas. I did buy the GPU used but it was from a friend of a friend who didnt OC it and I've not done much OCing nor has it been OCed for long.
My PSU has had a rough life. Once or twice I've had instability and the fan wasnt spinning (it has no fanless mode) and poking the fan with a pencil sent the fan to spin at max for a few minutes as it cooled down. But removing all nonessential drives and devices I thought could help reduce PSU load.
Thanks in advance
