Hi everyone,  
I**'**m helping my friend troubleshoot his PC. He is experiencing constant crashes in some games after playing for a while.  
Here are his PC specs:  
GPU: RTX 5060 **(**Ghost Edition**)**  
CPU: Intel Core i5-12400F  
RAM: 16GB  
PSU: Xigmatek M-Power 600W

The Problem: The games crash to desktop after playing for a specific period of time. Oddly enough, it only happens in certain games. For example, Dead by Daylight and LEGO games crash constantly, while some other games run completely fine without any issues.  
What we have tried so far:

Checked all temperatures **(**CPU & GPU**)**, and they are completely fine and normal under load.  
Cleaned the PC, RAM sticks, and other components from dust.  
Completely uninstalled the GPU drivers using DDU in Safe Mode and reinstalled the latest official NVIDIA drivers.  
Checked the +12V rail voltage, and it seems stable **(**not dropping heavily**)**.

Despite all of these steps, the crashing problem persists in those specific games.  
What could be the cause of this? Could it be a RAM instability issue **(**like XMP profile**)**, a game-specific software conflict, or something else?

Any help or suggestions would be highly appreciated! Thank you.
