Hey All,

I've been having this problem for about 1-2 months now and haven't been able to figure out a solution and it is driving me insane. While playing certain demanding games like Star Citizen and Apex Legends, my monitors will both randomly lose signal at the same time. I can still hear audio when this happens and the computer is still running, but the only way to get signal again is to force shutdown and restart. The graphics card also seems to max out its fans while in this lost signal state and goes back to normal after the restart. This doesn't seem to happen when I play games like League of Legends which are less demanding, and it doesn't seem to happen when I run stress tests such as Superposition Benchmark, Furmark, and OCCT (I don't run these for longer than 10 minutes). Sometime the issue will happen 5-10 minutes into a game I'm playing, other times it can take an hour or longer before it happens. I also see Windows Events logged such as dwm.exe being faulted.

I've read numerous other threads of similar issues and there never seems to be a concrete answer for what the problem may be. I've read it could be a driver issue, BIOS issue, NVIDIA settings issue, GSYNC issue, PSU issue, GPU issue, or Motherboard issue. I don't currently have spare parts to try out if it's a hardware problem, but I was wondering if there were things I could try before resorting to purchasing new hardware. This PC is new (just reaching half a year old) so I was hoping that it is a relatively simple setting/driver fix that I have not tried yet that fixes the issue.

Below are my PC specs:
Intel(R) Core™ Processor i9-11900K
GeForce RTX™ 3080 10GB GDDR6X
32GB (8GBx4) DDR4/3000MHz Dual Channel Memory (Crucial Ballistix Sport)
GIGABYTE Z590 UD AC ATX, ARGB, 802.11ac, 2.5GbE LAN, 2 PCIe x16, 2 PCIe x1, 5 SATA3, 3x M.2
1,000 Watts - Standard 80 Plus Gold Power Supply
Samsung 970 EVO Plus 2 TB M.2 NVMe
No Overclocking
Windows 10 Home Edition
BIOS Version/Date: American Megatrends International, LLC. F2, 1/6/2021

I also have two LG 27GL83A-B 27 Inch Ultragear QHD NVIDIA G-SYNC Compatible Monitors connected via DisplayPort that are both 1440p and both run at 144hz.

Any help would be greatly appreciated!

Hello aarif22827,

Can you post the brand and model name or number of the power supply (PSU).

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Can I ask that you do not quote every reply as we have to read the full post to make sure nothing gets missed,, thanks.

No Overclocking

Something is not right as some of the voltages are all over the place.

Voltage
CPU CORE: 1.280 V
MEMORY CONTROLLER: 2.752 V
+3.3V: 2.672 V

+5V: 4.596 V
-12V: -5.376 V
-5V: -6.336 V
+5V HIGH THRESHOLD: 3.790 V

Couple of things to do;

Power Profile
Active power scheme: High performance

Change the Windows Power Plan to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues, the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.


Try restoring the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" "most stable" or on newer boards "optimized" please note that if you have both the "most stable" and the "optimized" options in the BIOS you should choose the most stable" option as in this instance the "optimized" settings are a form of overclocking that can cause instability.

I've set the BIOS back to default + set the power plan back to Balanced and still get the same issue playing Apex.

Can we have a new Speccy url + let us know if the issue only happened with Apex or was it other games as well.


Download MiniToolBox and save the file to the Desktop.

Close the browser and run the tool, check the following options;

List Installed Programs
List Devices (Only Problems)
List Users, Partitions and Memory size

Click on Go.

Post the resulting log in your next reply for us if you will.

I think I've figured out the issue. I moved the GPU to the PCIe slot on the bottom of the board (which barely leaves any room for the card) and I haven't had the issue happen since. So something is wrong with the top PCIe slot. Will use compressed air on it and try it again otherwise I'll have to RMA to motherboard.
