| | Likely Cause | Solution | | :--- | :--- | :--- | | System won't power on | Power connections, front-panel connector | Double-check the 24-pin and 4/8-pin power cables and the front-panel power switch connection. | | No display on monitor | RAM not seated, CPU issue, video output | Reseat the RAM, ensure the CPU is correctly installed, and try the other video output (e.g., VGA instead of DVI). | | System turns on and off | RAM compatibility, power supply | Try booting with one stick of RAM in different slots. Test with a known working power supply if possible. | | USB ports not working | Driver issue, BIOS setting | Install the latest chipset drivers from ASUS. Ensure "Legacy USB Support" is enabled in the BIOS. | | Ethernet not working | Driver missing | Download the LAN driver on another PC, transfer it via USB, and install it manually. |
