The Silent Struggle: When Your Gaming PC Turns Off Unexpectedly


The PC specifications are as follows: MSI B450M PRO M2 motherboard, AMD Ryzen 7 2700x processor, 16GB Corsair RAM (currently in slot 2), MSI GeForce RTX 2060 GPU, Corsair VS650 power supply, 256GB SSD and 1TB hard drive for storage, running on Windows 10 22H2/10.0.19045.”


When faced with a perplexing issue where a PC intermittently powers off all peripherals while the system unit remains active, it’s essential to approach the problem methodically. The PC in question, with specifications including an MSI B450M PRO M2 motherboard, AMD Ryzen 7 2700x processor, 16GB Corsair RAM, MSI GeForce RTX 2060 GPU, Corsair VS650 power supply, 256GB SSD, and 1TB hard drive, running on Windows 10 22H2/10.0.19045, presents a unique challenge.


The peripherals, including monitors, keyboard, and Bluetooth-connected devices, lose power sporadically. This occurs during light tasks such as video streaming and is exacerbated when launching a game. The monitors signal loss of HDMI input, and after a brief period, all peripherals shut down, with the motherboard’s DRAM light turning on.

Potential Causes:


Power Supply Issues:

The Corsair VS650 power supply may be failing to deliver consistent power, especially under load.


Motherboard Faults:

The MSI B450M PRO M2 motherboard could have developed issues over time, particularly with the DRAM slots or other components.


Overheating Components:

Given the age of the PC, dust accumulation or thermal paste degradation could lead to overheating, causing safety shutdowns.


Software Conflicts:

Windows 10 updates or driver incompatibilities might be causing system instability.

Troubleshooting Steps:


Check Power Supply:

Test the power supply or replace it temporarily with another to rule out power issues.


Inspect Motherboard:

Look for visible damage or test with a single RAM stick in different slots.


Monitor Temperatures:

Use software to monitor component temperatures and check for overheating.


Update Drivers:

Ensure all drivers, especially the GPU driver, are up to date.


System Stability Tests:

Run stress tests to check for hardware stability under load.


The resolution may vary based on the identified cause. If the power supply is at fault, replacing it should resolve the issue. For motherboard faults, a replacement or repair may be necessary. Overheating can be addressed by cleaning the internals and applying new thermal paste. Software conflicts might require a system restore or reinstallation of the operating system.

In conclusion, the described symptoms suggest a complex interplay of potential hardware and software issues. A systematic approach to troubleshooting is crucial to isolate and resolve the underlying cause of the peripheral power-off problem.

This article serves as a guide to understanding and addressing the issue at hand. It’s always recommended to consult with or seek the assistance of a professional if the problem persists or if you’re uncomfortable performing any of the steps. Remember, when dealing with electronic devices, safety comes first. Always ensure the power is off before inspecting or adjusting any internal components.
