Windows 10: GPU to monitor is losing signal frequently Uncertain and unidentified issue

Hello, I've been having this issue with my PC for the last week or so where any monitor I use will lose a signal with my GPU frequently could be every 1 to 3 hours, seemingly random, whether it's idle or in use for gaming. For clarity, I run a dual monitor setup with differing resolutions. In my earlier setup where I did not face this issue, my main monitor 3840x2160, 60hz was used for gaming and my secondary monitor 1920x1080, 144hz was mostly used for low priority multitasking. However, in my newest setup, I used the older 3840x2160 monitor as my secondary monitor and the newer 2560x1440, 144hz monitor for gaming. I am convinced it has something to do with my GPU. However, if I may, I would like to pinpoint the exact cause, just to be sure it is my GPU and not something else I might be missing.

Whether I'm gaming or not, the monitor loses signal, but everything on the PC is still running - GPU is still powered, no beeps or lights flashing from the motherboard and it is still powered. After this happened a few times, what I've noticed is that the computer seems to do some kind of soft reboot, or perhaps it logs me out of my user account. I found this out because in one instance, I was able to recover from this 'crash' and I was able to get a signal and log back in. However, every other time this problem occurs I won't be able to reconnect the cable to get a signal - it stays black and I will have to restart my system where everything seems to return to normal until it eventually does it again.

So, after trying to diagnose this issue on my own, I believe I can safely rule out the possibility of overheating on the part of my GPU and/or CPU,and it has nothing to do with my monitors, all of them have lost signal whether in the dual setup or just one at a time. Temperatures stayed well within their components' respective safe zones while in and out of heavy use mostly gaming. However, I'm wondering if this could actually be attributed to my PSU in some way? Of the many forums I see discussing similar but not exactly the same problems, there is usual talk of PSU's going bad. My PSU in particular is not old at all, I bought it from a local store earlier this year to compliment my new components with the fairly new GPU purchased new in December 2019 and new CPU purchased new earlier this year.

Here are my PC Specs:

Intel Core i7 9700K 3.6GHz
32 GB RAM
Gigabyte RTX 2080 8GB
Samsung 860 EVO 1TB
WD Black 3TB HDD
750W PSU


While I have done some of the research on my own, I am not pretending to know more than I do. I only understand the basics, so if I seem to give off the impression that I know for certain what the issue is, I don't, and I apologize if it seems so. I just want to know what my next move should be, whether I invest in new hardware, or if I can fix it myself. Thank you in advance for any help.


*On a separate, but likely related note, I found this error in my Event Viewer to be somewhat relevant to my issue, but I don't understand how to read these kinds of errors from Event Viewer, so if you could let me know what this is, I'd greatly appreciate it. This happened around the time my monitor lost signal:

GTX 1050 ti Monitors Lose Signal

So far there's been a catalogue of symptoms, and the worrying thing is there are literally pages and pages of the same issue with GTX 1050's on the GeForce forums.

Symptoms so far:

• After getting to the logon screen, both my 4K monitor (plugged in via DP) and my 1080p monitor (plugged in via HDMI) spuriously lose signal for ~5 seconds then come back. This happens constantly with no apparent timing.

• Whenever I open a game launcher (not a game), or Google Chrome, the screen flickers again, only this time I get a Windows 10 event alert saying "application has been blocked from accessing graphics hardware".

• When I check event viewer System logs, the yellow triangle simply says "nvlddmkm stopped responding" in each case of the monitors losing signal.

Attempted fixes from numerous threads:

• Installed the latest Game Ready "stable" drivers, installed latest "beta" drivers, and also installed some random "stable" drivers from a month ago. Uninstalled previous drivers with DDU each time and restarted before and after installation. Issue seems to persist sporadically.
• Turned PCI Power Management off in Windows Power Settings. No change.
• Switched Power settings in NVidia Control Panel to Maximum Performance. No change.
• Gone into the registry and added a QWord(64bit) to CurrentControlSet001/Graphics/Drivers called "TdrDelay" and set it to 8 (also tried 10). No change.
• Tried unplugging the secondary monitor. Managed to play Warframe for an entire evening without a monitor signal loss.
• Switched secondary monitor to DVI Single Link cable to 1050 ti, and also tried secondary monitor on iGPU with primary monitor on 1050 ti. Still get signal losses on main monitor, secondary monitor does the same but is delayed (WTF?).
• Downclocked GPU 50Mhz. No change.
• Increased Power Limit by 5%. No change.

Fixes I still need to try:

• Try a different DP cable in main monitor/try HDMI cable instead.
  
• I get the signal loss when I open Chrome, going to turn off hardware acceleration as that apparently solves things
• Use a DWord(32bit) registry key instead of QWord for TdrDelay
• Going to try the 375.50 drivers, as they're allegedly old but stable for low power Pascal GPUs.
• Resetting CMOS for whatever reasons - some random guy said this solved his issues.

Fairly convinced it's not a hardware issue since there are so many people with the same issue as me. One slight glimmer of explanation is that Micron memory may be at fault, I need to check if its Samsung or Micron stuff on mine. Apparently there were some GTX 1070 stability issues with Micron VRAM that were fixed with an update.

My entire system has been stable for years, sporting a R9 295x2 up until 6 months ago with no stability problems. Doubt it's PSU related. Motherboard is also on the latest 2.50 BIOS.

Help me TPU, you're my only hope.

 

Unidentified network

Hi, Badrobot and thanks for your suggestion. Unfortunately the issue is still not resolved. The connection still shows as Unidentified and it disconnects frequently.

 

Monitors Lose Signal On Boot


I have 3 Benq xl2720z monitors all using dp.

In the morning I went to turn on my monitors to find out there was no signal in any of them. I then rebooted my computer and when I got to the spinning orb, my computers faded to black in the middle of it and lost signal. I didn't even get to the login screen.

I then decided to try each monitor by themselves starting with the left monitor. this monitor managed to the login and to the desktop. However it still faded to black as if it was about to lose signal in the middle of the spinning orb. However it managed to recover I guess and show the login. The part that I noticed is that it took much less time to normally to get to the login so something is not right.

I then tried the middle monitor. The first try I got to the desktop just to lose signal a second later. The second try I lost signal during the spinning orb.

For the right monitor, I lost signal when I got to the desktop. Didn't bother trying again with it.

Since the left monitor I could get somewhere I decided to go and plug that one in so I could go and write this, however I accidently plugged in the middle monitor but it was idea I did because something new happened.

I got to the login and desktop fine and it never faded to pure black in the middle of the spinning orb. It showed the whole animation but the second one with the blue screen. It also longer to boot up which was how it was suppose to be.

So I no idea what is going on. It all feels random. Can someone help me with this?

I'm going to try rebooting again and see if the middle monitor is fine now and then I'm going to try all 3 together.

EDIT: Tried again with the middle monitor, it booted without issues. Tried again with 3 monitors, it booted to desktop without going to no signal, however the boot was shorter. Is there a reason for Windows 10 to not go to the seconded spinning orb with the blue screen?
