What does updating the BIOS do?

Like operating system and driver revisions, a BIOS update contains feature enhancements or changes that help keep your system software current and compatible with other system modules (hardware, firmware, drivers, and software) as well as providing security updates and increased stability.

Is it a good idea to update BIOS?

In general, you shouldn’t need to update your BIOS that often. Installing (or “flashing”) a new BIOS is more dangerous than updating a simple Windows program, and if something goes wrong during the process, you could end up bricking your computer.
