Basic Input/Output System or commonly known as BIOS is a program or firmware that initializes all the connected hardware components in your PC and starts boot process for loading the operating system. When you power on your computer then the first program to load is BIOS that checks or test whether all the connected components i.e. CPU, RAM, Hard disk, Graphics Card and Input/Output devices are OK and then it proceed further to load boot loader so that the operation system can start on your computer.
Earlier BIOS was stored in ROM (Read Only Memory) so that it cannot be altered by any malicious program or viruses, but now it is stored in flash memory so that it can be updated without having it to remove physically from the motherboard. The process of updating or loading a new BIOS program is known as Flashing of BIOS. Flashing of BIOS is a risky process because if something wrong happens then you can brick your computer. But now there are very easy and safe methods available by which you can flash your computer BIOS with minimum risk involved. It is generally not recommended to update your BIOS if you are not facing any major issues with your PC. So here in this post I will list down some cases where you may want to update to BIOS to a newer one.
