To update the BIOS, download the latest BIOS file from the ASUS support website. Extract the file to a USB drive. Enter the BIOS setup by pressing 'Del' during boot, go to the 'Tools' menu, and select 'EZ Flash'. Choose the BIOS file from the USB drive to update.
The ASUS H81M-D motherboard supports DDR3 memory with speeds of 1600/1333 MHz. It has two DIMM slots, supporting up to 16GB of total RAM.
Ensure that the power supply is connected properly and the monitor is functioning. Check if the RAM is seated correctly, and if using a graphics card, ensure it is properly installed. Try clearing the CMOS to reset the BIOS settings.
To reset the CMOS, turn off the computer and unplug it. Locate the CMOS jumper on the motherboard and move it from the default position to the reset position for a few seconds, then move it back. Alternatively, removing the CMOS battery for a few minutes can achieve the same result.
The ASUS H81M-D supports Intel 4th generation Core i7/i5/i3/Pentium/Celeron processors, compatible with the LGA 1150 socket.
To enable Intel Virtualization Technology, enter the BIOS by pressing 'Del' during boot. Navigate to the 'Advanced' tab, select 'CPU Configuration', and then enable Intel Virtualization Technology. Save changes and exit.
First, ensure the installation media (USB or DVD) is prepared. Enter the BIOS setup and set the boot priority to the installation media. Restart the computer, follow the on-screen prompts to install the OS, and ensure all drivers are installed once the OS is set up.
Refer to the motherboard manual for the pin layout. The front panel connectors include the power switch, reset switch, power LED, and HDD LED. Carefully connect each wire from the case to the corresponding pins on the motherboard.
Check the SATA cable and power connections to ensure they are secure. Enter the BIOS to see if the drive is detected. If not, try a different SATA port or cable. Ensure the drive is initialized within the operating system's disk management tool.
Ensure that the case has adequate airflow by adding additional fans if necessary. Clean any dust from the CPU cooler and case fans. Consider upgrading to a more efficient CPU cooler if temperatures remain high.
