Troubleshooting Recurrent PC Crashes During Gaming: A Case Study

Experiencing unexpected system restarts and blue screens while gaming can be frustrating and disruptive. In this article, we examine a real-world scenario where a gamer faced recurring crashes, the steps taken to resolve them, and potential causes to consider for future troubleshooting.

Background and Initial Issue

The user encountered system crashes specifically during moderate to heavy gaming sessions with titles such as Dune Awakening and Clair Obscure. Interestingly, less demanding or different genres such as Valorant did not trigger these issues. The crashes manifested as sudden restarts or blue screens, accompanied by event viewer error code 0x00040049.

First Repair Efforts

The initial problem intensified over time; eventually, the user could no longer launch games without crashes. Seeking resolution, professional repair services were engaged. The technician diagnosed the problem as likely related to the graphics card (GPU), recommending its replacement. Additionally, the user upgraded their system by adding more RAM and an extra terabyte of storage, hoping to alleviate the issue.

Current Situation and Recurrence

Approximately one month later, the same instability reemerged. The system again crashes spontaneously while gaming or experiences blue screens. Despite efforts such as reinstalling Windows, updating drivers, and checking SSD health, the problem persists.

The user is now considering other potential causes, including:

Power Supply Unit (PSU)
Central Processing Unit (CPU)

However, they are unsure how to diagnose these components further.
