If you are not comfortable in performing the steps indicated by your motherboard's manual, please contact your motherboard manufacturer or system assembler for assistance.It is important to keep the components on your motherboard in good working order, not just for playing games but for general system performance.Your computer's BIOS - Basic Input/Output System - is a chip on the motherboard which contains enough information to allow it to start up before the main operating system begins to load.Here's everything you need to know about how to update a PC BIOS, whether traditional or the newer UEFI standard.When the check is complete, it will ask if you wish to go ahead with the update.
Then type “msinfo32” to bring up your computer’s System Information log.
Download the latest BIOS update file from the Asus website. When this is complete, the screen will show details on the current BIOS in the upper left.
On the lower half of the screen, to the left, you use the arrow keys to select the drive letter of the CD-ROM or USB flash drive, and then press the "Tab" key to switch to the right pane and select the BIOS update file.
Asus is one such company, using an interface that they call EZ Flash, which can boot the PC to a level capable of reading from a CD or USB flash drive to update the BIOS quickly and easily.
The M2N-MX is one such motherboard that has EZ Flash. Rename the resultant file in the "8.3" format, where the file name is eight characters or fewer and the extension is three characters. Wait for EZ Flash to finish checking the current system BIOS.
