  • Check front panel connectors (power button, reset) are correctly attached to the motherboard.
• No Display:
  • Ensure the graphics card is properly seated in its PCIe slot and has adequate power.
  • Check monitor cable connections.
  • If using integrated graphics, ensure your CPU supports it and the display cable is connected to the motherboard's video output.
  • Try reseating RAM modules.
• Memory Issues (e.g., long training times, instability):
  • Ensure RAM modules are fully seated in the correct slots according to the motherboard manual (usually A2/B2 for dual channel).
  • Update BIOS to the latest version, as memory compatibility and training often improve with updates.
  • Disable or adjust EXPO/XMP profiles in BIOS if experiencing instability.
• Driver Problems:
  • Download and install the latest drivers directly from the ASUS support website for your specific motherboard model.
