Troubleshooting PC Resets: Issues with Power Strips and Light Switches

Hello, tech enthusiasts!

I recently encountered a peculiar challenge with my computer setup that I hope to get some insights on. Here’s the situation: whenever I plug in or unplug devices from the power strip connected to my PC, everything seems to reset. The monitor goes dark, any games I had running crash, and my Corsair iCUE software reverts to its default settings. It’s quite the hassle, requiring me to wait at least ten seconds before everything powers back up normally. Interestingly, this also occurs when I flip specific light switches in the room.

This isn’t my first encounter with this problem—my previous PC exhibited the same erratic behavior, so I’m skeptical that the issue lies solely with the hardware itself.

To give you some context, I’m currently using a Brennenstuhl Premium-Line 8-way extension lead, which I trust is of decent quality. As far as I know, the electrical wiring in my home complies with European standards, yet it feels as though I’m encountering some sort of power surge or voltage dip that’s impacting my system.

Have any of you faced a similar issue? I’m curious if this could be related to grounding problems, subpar wiring, or perhaps another underlying cause. Any insights or suggestions you might have would be greatly appreciated!

Thank you for your time and expertise!

  1. Hi there,

    It sounds like your system may be experiencing power fluctuations or electrical noise caused by switching devices or power surges. Here are some troubleshooting steps and suggestions that might help:

    • Use a Surge Protector or UPS: Ensure your PC is connected through a high-quality surge protector or an Uninterruptible Power Supply (UPS). This can help regulate voltage spikes and prevent sudden resets caused by power instability.
    • Check Grounding and Wiring: Verify that your electrical outlets and wiring are properly grounded. Grounding issues can cause voltage fluctuations that affect sensitive electronic devices.
    • Avoid Plugging Devices into the Same Power Strip: Plugging high-current devices or switching circuits into the same extension can create electrical noise. Consider separating your PC and peripherals onto different outlets or strips.
    • Use Filtered Power Strips: Consider switching to power strips with built-in noise filtering. This reduces electrical interference that may be affecting your PC.
    • Inspect for Electrical Interference: Certain light switches or appliances can introduce electrical noise. If you notice a pattern, try to identify and replace problematic switches or install noise filters.
    • Check Your Power Supply Unit (PSU): A faulty or insufficient PSU may also cause resets during power fluctuations. If possible, test with a known-good PSU
