PC crashes when using single GPU in SLI setup


Hi guys, so as the title says when I use a single GPU connected and run a game it would hard crash losing signal with no error or BSD.

So the problem is, that ever since I built this machine in around 6 months ago I was getting lots of hiccups, stuttering and frame drops on many if not all games that I ran. At first, I thought it could be due to the SLI not being fully supported on games so I disabled SLI from the Nvidia control panel. However, the same performance issues remained, I tried taking out the HB bridge that came with the mobo which has double ports, same thing, then I tried to use a SINGLE GPU. And that's when the main issue starts, for about random minutes in-game, the computer would lose display signal on every monitor and without any notification, it would just sit there like working but nonresponsive with the 3 displays having lost signal. Only resetting the entire system worked. However, the performance issues when it does not crash are gone. I tried using another PSU to test and the same thing happens. When using a single GPU any of the two I have the system will crash on random game moments, it seems its not related to a complex demanding scene or power demanding moment. An old not that bad optimized game like Diablo 3 would crash when GPU Temp was practically idle 50°C. I tried updating both gpu bioses, and even the mobo but nothing seems to be fixing the crash. I also tried uninstalling GPU drivers with DDU several times on safe-mode. I detected several errors on the Windows Event Viewer.

If the event originated on another computer, the display information had to be saved with the event.

try re-seating the first (top) gpu. try a reinstall of windows. make sure nothing is shorting out on the gpu/mobo. is everything plugged in correctly? update GPU driver.

  • I tried re-seating both. Haven't tried an OS re-install.
  • Yes I double checked everything before changing cards.
  • GPU drivers are up to date.

Last night I disabled TDR to test if it would make any difference and somehow for the entire 6hs of sleep that I left the computer with OCCT running dx-9 test, the app reported no errors, and the computer was still running, so I tried Forza Horizon 4 to see if an actual game would crash it and to my surprise it did not for the 30min I could test it, however I did notice something strange, somehow now screen tearing can be seen, before changing the TDR setting, i had V-sync disabled and I did not notice any tearing, will try enabling V-sync to see if that single GPU on port 1 running at 16x does work without crashes.
