Issue with ACPI 2/dwm.exe causing unexpected shutdown during gaming
Issue with ACPI 2/dwm.exe causing unexpected shutdown during gaming
I own an Intel i9 10850k, Asus RTX 3060ti, Gigabyte Z490 motherboard, GSkill 32 gb RAM modules, Corsair power supply. Recently I switched the GPU from EVGA 3080 to Asus 3060ti, believing it would fix the problem. This issue occurs randomly while playing in Valorant and sometimes during Furmark stress tests. The PC will shut down abruptly, either restarting itself or requiring manual reboot. Occasionally, I hear game audio but no visuals appear. In the Event Viewer, I see an error with ACPI 2 Event ID 56:
"The description for Event ID 56 from source Application Popup cannot be found." This suggests the component triggering this event isn’t installed or the installation is corrupted. You may need to reinstall or repair that component on your machine. If the event came from another device, the display information must have been saved with it.
Previous experience with the EVGA 3080 showed a similar problem with dwm.exe failing and a black screen appearing. Changing to the 3060ti didn’t resolve the issue, so I reinstalled Windows, updated drivers, and reinstalled drivers again—without success. The problem only appears during gaming or stress tests. I use the PC for extended work sessions and nothing happens.
Could it be related to my power supply or the power cables? Or is it the motherboard or processor? I have the PC connected to a power strip with two monitors; could this be preventing the system from receiving power properly? Any advice would be greatly appreciated.

Hi, thank you for your message. I reviewed that post and found the fix involved swapping the OEM GPU, which I did. The article also discusses the dwm.exe crash. I haven’t encountered that error anymore after switching from a 3080 to a 3060ti. Still, I notice the ACPI 2 crash remains, causing a black screen and shutdowns.

The GPU replacement is complete, but I’m unsure about next steps.

Hi,
Relevant to mention RAM, I just noticed a discussion online about games crashing because XMP is turned off in the Gigabyte motherboard BIOS. I turned it on recently and didn’t realize my memory speed was at 2600MHZ, but now it’s up to 3600MHZ. I’m not sure if this will solve the problem.
I haven’t checked RAM performance further, though I do have the newest drivers installed.
Enabling XMP didn't resolve the problem; it happened again today.
I'm confused—I first assumed it was related to the GPU, but even with a different one, the same issue persists.
Hello, I'm facing the same problem with the same motherboard. Have you discovered a solution to resolve it?
Hello

I'm not sure if we're facing the same problem, but I found a solution for mine.
I have two 8-pin DDR5 RAM modules, and when connected properly in dual channel mode they operate at 4800 Mhz.
However, if I connect them incorrectly—like placing one next to the other—they drop to 4533 Mhz and the crashes stop.
You can also connect them correctly and enable XMP in the BIOS (factory-optimized settings for RAM) to reach 5200 Mhz, which works perfectly without any issues.
