My friend’s computer has been experiencing unexpected shutdowns that occur without warning. These shutdowns tend to happen during gaming sessions, although there have been instances where it has happened while he’s watching videos on YouTube. According to the Event Viewer, there is evidence of these random shutdowns.

The process C:\Windows\system32\winlogon.exe (SPENCER-DESKTOP) has initiated the power off of computer SPENCER-DESKTOP on behalf of user NT_AUTHORITY\SYSTEM for the following reason: No title for this reason could be found
Reason Code: 0x500ff
Shutdown Type: power off

param1  C:\Windows\system32\winlogon.exe (SPENCER-DESKTOP)
param3  No title for this reason could be found
param4  0x500ff
param5  power off

I believe that this specific incident was the cause of the problem. The computer in question is a pre-built gaming PC made by Cyberpower. I am open to any recommendations that may help resolve the issue.
