Peripherals Turn Off During Marvel Rivals Animations & Premiere Pro, PC Stays On

Understanding and Troubleshooting Peripherals Disconnection During Graphics-Intensive Tasks: A Case Study

Introduction

Many PC enthusiasts and professionals encounter perplexing hardware issues that disrupt workflow and gaming experiences. One such scenario involves peripherals—monitor, keyboard, mouse, and headset—occasionally turning off during specific applications or animations while the PC remains powered on. This article explores a real-world case, examines potential causes, and offers troubleshooting steps to resolve similar problems.

Scenario Overview

A user reports intermittent disconnections of peripherals during two scenarios:
– Playing the game Marvel Rivals, specifically when a new skin (Cloak & Dagger) animation activates.
– Importing videos in Adobe Premiere Pro.

In both cases, the peripherals’ displays (monitor, keyboard, mouse, headset) turn off, yet the PC’s core components—fans, system lights—remain operational. Notably, these issues are sporadic, occurring during specific animations or video processing, but not consistently across all scenarios.

Initial Observations and Testing

The user conducted several key tests:
– Running Marvel Rivals with individual RAM modules (8GB each) resulted in stable gameplay.
– However, when both RAM sticks (total 16GB) are engaged simultaneously, issues reappear during animations and video imports.
– Switching RAM slots did not mitigate the symptom.
– Updating the GPU driver did not resolve the problem.
– Stress-tests on CPU (via Cinebench) and GPU (via FurMark and Unigine Heaven) yielded stable results, with temperatures within normal operational ranges:
– CPU: Max 88°C
– GPU: Max 71°C, with high utilization (92%)

Crucial Observation: The Role of Integrated Graphics

A turning point in the troubleshooting process was switching from the dedicated GPU (Intel Arc A750) back to the integrated graphics of the AMD Ryzen 5 5600G. When operating with integrated graphics:
– The Peripheral Disconnection issue was eliminated.
– Animations in Marvel Rivals and video import in Premiere Pro proceeded smoothly.

Reverting to the dedicated GPU resurrected the problem, indicating a strong correlation between the discrete GPU usage and the peripheral disconnections during intensive graphical operations.

Potential Causes and Considerations

Given these findings, several avenues can be considered:
