Understanding and Troubleshooting Peripherals Disconnection During High-Intensity Applications on Modern PCs
Experiencing intermittent peripheral disconnections can be a perplexing issue for PC users, especially when it occurs during demanding activities such as gaming or video editing. Recently, a user reported a peculiar problem where their monitor, keyboard, mouse, and headset randomly shut off during specific in-game animations in Marvel Rivals and while working in Adobe Premiere Pro, despite the computer remaining powered on. This phenomenon, though sporadic, raises important questions about hardware compatibility, driver stability, and graphics configuration.
Detailed Description of the Issue
The user observed that during Marvel Rivals, peripherals would unexpectedly deactivate specifically when a new skin animation (notably for Cloak & Dagger) plays. Older skins did not trigger the issue, and occasional disruptions also occurred in the game lobby. Additionally, the same disconnection pattern appeared during video imports in Premiere Pro, indicating a problem not confined solely to gaming.
Interestingly, when testing RAM modules individually, the game performed normally, but problems reemerged under multi-stick configurations, suggesting potential issues related to memory or power distribution. Despite attempting RAM slot swaps and driver updates, the problem persisted.
Stress Testing and Hardware Diagnostics
The user conducted stress tests on their CPU and GPU to rule out overheating or faulty hardware. The CPU’s maximum temperature during Cinebench was 88°C, and the GPU maintained a temperature of 71°C after a prolonged FurMark session, with no apparent thermal issues. This points away from thermal throttling or overheating as the root cause.
Key Observation: Graphics Configuration Impact
A critical insight was gained by leveraging the system’s integrated graphics—disabling the dedicated Intel Arc A750 GPU and switching to the onboard Ryzen 5 5600G graphics entirely eliminated the peripheral disconnections. The problem only reappeared when reverting to the discrete GPU.
This behavior strongly suggests a compatibility or driver-related issue involving the Intel Arc GPU, particularly in interaction with specific applications and animations.
Potential Causes and Troubleshooting Steps
-
Graphics Driver Stability: The initial step involves ensuring that the latest compatible drivers are installed. Since driver updates were attempted without resolution, consider rolling back to a more stable previous version or testing beta drivers if available.
-
Power Supply Considerations: Although the PSU is rated at 650W and certified, intermittent power delivery or incompatibility under load can cause peripheral disruptions. Testing with a different
