ASUS P5N-EM HDMI User Manual

To update the BIOS, download the latest BIOS update file from the ASUS support website. Use the ASUS EZ Flash utility in the BIOS setup to load and update the new BIOS file from a USB drive.
Check all power connections and ensure the RAM and GPU are seated properly. Clear the CMOS to reset BIOS settings, and try booting with minimal hardware to identify any faulty components.
Ensure that the HDMI cable is connected to both the motherboard and a compatible device. In the BIOS, set onboard audio to 'Enabled'. In Windows, set the HDMI output as the default audio playback device.
The ASUS P5N-EM HDMI motherboard supports up to 8GB of DDR2 RAM with speeds of 667/800 MHz across two DIMM slots.
Ensure that the CPU cooler is properly installed and the thermal paste is applied correctly. Improve airflow by cleaning dust from fans and heatsinks, and consider adding additional cooling fans if necessary.
Check the BIOS settings to ensure USB ports are enabled. Update the chipset drivers from the ASUS support site. If the issue persists, check for hardware damage or consider a powered USB hub.
To reset the BIOS password, locate the CMOS jumper on the motherboard. Move the jumper from the default position to the reset position for about 10 seconds, then return it to its original position.
Ensure the SATA cables are connected securely to both the motherboard and the drive. Check the BIOS settings to ensure SATA ports are enabled and set to the correct mode (IDE or AHCI).
The ASUS P5N-EM HDMI has limited overclocking capabilities. You can adjust the FSB (Front Side Bus) and voltage settings in the BIOS, but stability is not guaranteed, and it may void warranties.
Regularly clean dust from the motherboard and components, ensure all connections are secure, update BIOS and drivers periodically, and monitor temperatures to prevent overheating.
