Solved Spontaneous Crash/Reboot

[uvfuture]

Hello! Recently built a desktop. Everything appears to be working correctly except that there are spontaneous crash/reboots, generally when doing something graphically intensive (playing a game).

OS: Windows 11

Motherboard is an MSI Z690 Carbon Wifi. Debug codes at crash are (in order) 7C 5C 55 7C.

7C and 5C are listed as "reserved for future codes" ... unclear what they indicate.

55 makes it seem like it's a memory issue, but RAM is visible and running at correct speed in BIOS, Task Manager, and iCUE software.

On boot, there is an A2 POST code, however all of my storage drives (2 NME m.2, 1 sata HDD) appear to be functioning properly. Maybe this relates to the fan controller? Fans generally need iCUE software at startup to function as intended.

Temperatures are remaining in 30-50C degree range

If you can access the system even in safe mode.

So other can assist let get a speccy report.

Do not forget to post the make and model of the PSU if this is a desktop.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.
