No Power or Boot

This is the most frustrating problem, right? Your PC just won't turn on. Here’s what to check:

  • Power Supply: Make sure the power supply is actually working! Use a power supply tester or try swapping it out with a known good unit to rule it out. Also, double-check that the power cable is securely connected to both the power supply and the wall outlet. Sometimes, it's as simple as a loose connection.
  • Power Button: Seriously, make sure the power button on your case is properly connected to the motherboard. Check the front panel connectors in your motherboard manual to ensure the power button wires are in the correct place. It's an easy fix, but often overlooked.
  • CPU and RAM: Reseat the CPU and RAM modules. Sometimes, they can become dislodged. Make sure your CPU is properly seated in the socket and that your RAM modules are firmly clicked into their slots. Also, check that your RAM is compatible with the motherboard.
  • Short Circuit: Inspect your motherboard for any signs of a short circuit. Look for any loose screws or metal objects that may be touching the board. Remove all unnecessary components to narrow down the problem.
  • BIOS Issues: If you're getting power but no boot, the BIOS might be corrupted. Try to flash the BIOS. If you have a BIOS flashback feature, use it. Refer to the ASUS A520MK user manual for instructions. This can sometimes fix a corrupted BIOS preventing the system from starting.

No Display

If the PC powers on but there's no display, here's what to do:

  • Graphics Card: Ensure your graphics card is properly seated in the PCIe slot. Try reseating it. If you have an integrated graphics processor (IGP), try connecting your monitor to the motherboard's video output to see if that works. This helps determine if the issue is with the graphics card or the motherboard itself. If the display works using the IGP, the graphics card could be the culprit.
  • Monitor Connection: Verify the monitor cable (HDMI, DisplayPort, etc.) is securely connected to both the graphics card (or motherboard) and the monitor. Test with a different cable and monitor to eliminate those as the problem.
  • RAM: Reseat your RAM modules. Try booting with only one RAM stick at a time to check if one of the modules is faulty. Run a memory test using a bootable USB drive (like Memtest86) to check the integrity of your RAM.
  • CPU: The CPU can also cause display issues. While less common than other components, ensuring the CPU is properly seated and functioning can resolve display issues. Check for bent pins or other signs of damage on the CPU socket. Try reseating the CPU, and carefully inspect for damage.
  • BIOS: A corrupted BIOS can prevent the system from displaying anything. Try to reset the BIOS by removing the CMOS battery for a few minutes or using the CMOS reset jumper. After resetting the CMOS, attempt to boot the system again.

USB Ports Not Working

USB ports not working can be a real pain. Here’s how to fix it:

  • Check Connections: Ensure all front panel USB connectors are properly connected to the motherboard. Double-check your case's front panel USB connectors are securely plugged into the correct headers on the motherboard.
  • Drivers: Reinstall or update your USB drivers. You can download the latest drivers from the ASUS website for your A520MK. In the Device Manager (Windows), look for any devices with exclamation marks, indicating driver issues. Update or reinstall those drivers.
  • BIOS Settings: Check the BIOS settings to ensure USB ports are enabled. Make sure the USB configuration is set correctly within the BIOS. Check the BIOS for settings like “USB Legacy Support” or “XHCI Hand-off.”
  • Power Supply: Insufficient power can sometimes cause USB ports to fail. Ensure your power supply has enough wattage to handle all your connected devices. Try disconnecting some USB devices to see if that resolves the issue.
  • Short Circuit: Inspect the USB ports and the surrounding areas on the motherboard for any signs of damage or short circuits. This includes bent pins, broken connectors, or other visual anomalies. A short circuit could disable the USB ports.

Overheating

Overheating can cause all sorts of problems. Here's how to prevent and solve it:

  • CPU Cooler: Make sure your CPU cooler is properly installed and making good contact with the CPU. Use high-quality thermal paste and reapply it if necessary. Check that the cooler is securely mounted. The cooler must make solid contact with the CPU's surface to dissipate heat efficiently.
  • Case Fans: Ensure you have adequate case fans for airflow. Position fans to intake cool air and exhaust hot air effectively. Optimize the airflow within your case by ensuring fans are installed correctly. Proper airflow is essential to prevent heat buildup.
  • Dust: Clean out any dust buildup from your PC. Dust can act as an insulator and prevent heat from escaping. Regularly clean your case, fans, and heatsinks to ensure optimal cooling performance.
  • Monitor Temperatures: Use monitoring software (like HWMonitor or Core Temp) to keep an eye on your CPU and GPU temperatures. If the temperatures are too high, you have a cooling problem. Take appropriate steps to improve cooling immediately.

Advanced Troubleshooting Techniques

Sometimes, the basic steps aren't enough. Here are some more advanced techniques:
