How to Fix: Desktop gaming computer weird problem at home but not at shop (Might be pow

Desktop gaming computer experiencing random crashes and flickering screen despite UPS power supply, with graphical glitches fixed by alt-tabbing.


The issue you're experiencing with your desktop gaming computer is a complex one, and it's not uncommon for such problems to arise from power-related issues. When the computer was working fine at the shop but crashed at home, it could be due to various factors such as power surges, electrical noise, or even a faulty power supply unit (PSU). The fact that you've already replaced the PSU with an UPS and the issue persists suggests that there might be another power-related component causing the problem.

⚠️ Common Causes

  • Power surges or electrical noise from the mains supply
  • A faulty power supply unit (PSU) or a failing component within it
  • Overheating of critical components, such as the GPU or CPU

🛠️ Step-by-Step Verified Fixes

Method 1: Replace the PSU with a high-quality, certified unit

  1. Step 1: Purchase a reputable, high-wattage PSU that matches or exceeds the original's specifications.
  2. Step 2: Install the new PSU and ensure it's properly seated and connected to the motherboard and other components.

Method 2: Add a power conditioning unit (PCU) or a line conditioner

  1. Step 1: Purchase a PCU that can filter out electrical noise and provide a stable, clean power supply.
  2. Step 2: Connect the PCU to both the mains supply and the computer's PSU, ensuring it's properly configured and set up.

💡 Conclusion

To resolve this issue, you may need to investigate further or try a combination of the above methods. It's also essential to ensure your computer is properly maintained, with regular cleaning and dust removal from critical components. If the problem persists, consider consulting a professional for further assistance.
