  • Ensure the power supply is switched on.
  • Verify the front panel power button connection to the motherboard.
• No Display:
  • Ensure the monitor is connected to the graphics card (or motherboard if using integrated graphics).
  • Reseat the graphics card and RAM modules.
  • Check the EZ Debug LED indicators on the motherboard for clues (CPU, DRAM, VGA, BOOT).
• System Instability/Crashes:
  • Check CPU and GPU temperatures.
  • Ensure RAM is properly seated and compatible.
  • Update BIOS and all drivers to the latest versions.
• Network Connectivity Issues:
  • For wired LAN, check the Ethernet cable and router connection.
