Question Event ID 56 - ACPI 2/dwm.exe randomly shutting off PC when gaming

[jptnpjpt]

I have an intel i9 10850k, Asus RTX 3060ti, Gigabyte Z490 Motherboard, GSkill 32 gb RAM sticks, Corsair power supply. I recently changed the GPU from EVGA 3080 to Asus 3060ti thinking it would resolve this issue. It happens randomly when I game in Valorant, and sometimes with Furmark stress test as well. The PC just shuts off, and either restarts on its own, or I have to restart it manually. Occasionally, i hear the game's sound, but no visuals. When I check event viewer, I see error about ACPI 2 Event ID 56:

The description for Event ID 56 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
ACPI 2

Before, with the EVGA 3080, I also got a dwm.exe stopped working issue ALONG WITH the black screen. I thought the GPU was the culprit, clearly it is not since I changed to a 3060ti and issue still exists. I also reinstalled windows, made sure drivers are up to date, reinstalled drivers - to no success. The issue ONLY happens when I game/stress test. I use the PC for hours for work and nothing happens.
Could it be my power supply or the power cables ? Or could it be the Motherboard or Processor ? I have my PC connected to a power strips along with the 2 monitors, could that be the issue maybe with the PC not getting power ? Any suggestions is appreciated.

Hi, thank you for your reply. I did view that post, and the solution eventually was to replace the OEM GPU, which I did. Also, that post focuses on the dwm.exe crash. I have not seen that error particularly now after changing the GPU from 3080 to 3060ti. Now still, i see the ACPI 2 crash, but yes, similar issue of black screen and shutting down still exists . GPU has already been replaced, idk what to do now .

all driver and cpu chipset are the latest one also did you try memtest ram also check in the event viewer if there is any power one .

Hi,
Funny you should mention RAM, i just saw a post elsewhere about games crashing due to XMP being disabled in the Gigabyte motherboard BIOS. I enabled it just now, i did not realize my memory was running at 2600MHZ, now it is running at 3600MHZ. I do not know if that will fix the issue however.

I have not done any other checks for RAM performance, but i do know i have the latest drivers for everything.

Enabling XMP did NOT help, the issue occurred again today just now . I am stumped , i initially thought it was the GPU, but with a new GPU also same issue.

I tried memtest, all results came back as PASSED. So, GPU was replaced from 3080 to 3060ti and RAM has passed, PSU or MoBo/CPU are left. Any thoughts would be appreciated .
