Updating the BIOS, also known as "flashing the BIOS," replaces the BIOS firmware. When completed successfully, a BIOS update can fix or enhance aspects of a computer's performance, or provide support for newly installed hardware. However, if an incorrect update is installed or if the update process is interrupted, the motherboard can be permanently damaged, leaving the computer unable to boot. It is recommended to update your BIOS only if one or more of the following conditions apply:
The update fixes a problem with your computer.
The update enhances your computer's performance in a desired way.
You are planning to change the operating system, processor, or other feature(s), and the current BIOS version will not support the new configuration.
Proper research is crucial; read through the latest BIOS updates, it fixes, and determine if any of them are applicable to your situation, if they're not, you could be taking an expensive shot in the dark, hence why flashing is a last ditch effort. If you can verify through the manufacturer's documentation that the BIOS update addresses your issue then by all means, perform that procedure first.
