Hi,
it will be a wild ride so buckle up.
My system is based on X570 chipset with 4x8GB of ram, 5800x3D and 7900XTX on top of that. (850W Corsair PSU, more on that later)
My system started crashing while using 3 FHD monitors, each as separate entity. It crash while some kind of game is running.( You name it: Diablo 2, Last Epoch, Diablo IV, Against the Storm, Gloomhaven). Its fine browsing web and other application what hinted maybe at psu?
Crash is not happening when i'm using two monitors (in any configuration) or 3 of them connected by eyefinity.
What i have done so far :
Reinstalling drivers with ddu - drivers solo and with adrenaline
Reinstalling BIOS
Reinstalling chipset Drivers
Reinstalling every other driver i can think of (wi-fi, bt, monitors, pcielan)
Running clean BIOS
Running on different DP cables
Running on a different 1200w nzxt PSU
Reinstalling windows
Running under volted with low power target GPU
Deleted many not needed resolutions. (using SRE and CRU)
Updated to windows 11
Some things in registry
Running on an old GTX 960 solved this issue as well, worked well with 3 separate monitors.
Thermally everything is all right CPU around 75-80 degrees and GPU under stress test (which does not trigger crash) around 65 with delta to hot spot around 10 degrees.
Everything is fine if i'm running on just two or in ultrawide setup which is not optimal if i would like to set up youtube on full screen on my left, game in the middle and discord on my right.
