If you consult any repair or IT person regarding the same then they will suggest or give you instructions to update your BIOS before any further troubleshooting. As in many cases simply updating BIOS fixes the issue, so there is no need for further troubleshooting.
What is BIOS?
BIOS stands for Basic Input and Output System and it is a piece of software present inside a small memory chip on the PC’s motherboard which initializes all the other devices on your PC, like the CPU, GPU, etc. It acts as an interface between the computer’s hardware and its operating system such as Windows 10. So by now, you must know that the BIOS is a very crucial part of any PC. It is available inside every PC sitting on the motherboard to provide life to your system and it’s components, just like oxygen provides life to human beings.
The BIOS incorporates the instructions which PC needs to carry out in sequence in order for the proper working of the system. For example, the BIOS contains instructions such as whether to boot from the network or hard drive, which operating system should be booted by default, etc. It is used to identify & configure hardware components such as the floppy drive, hard drive, optical drive, memory, CPU, Play devices, etc.
A few years ago, motherboard manufacturers in partnership with Microsoft and Intel introduced the replacement of BIOS chips which are called UEFI (Unified Extensible Firmware Interface). Legacy BIOS was first introduced by Intel as Intel Boot Initiative and have been nearly there for 25 years as the number one boot system. But like all other great things which come to an end, the legacy BIOS has been replaced by the popular UEFI (Unified Extensible Firmware Interface). The reason for UEFI replacing legacy BIOS is that UEFI supports large disk size, faster boot times (Fast Startup), more secure, etc.
The BIOS manufacturers come with BIOS update time to time to enhance the user experience and to provide a better working environment. Sometimes, the updates also lead to some problems because of which some users do not prefer to update their BIOS. But no matter how much you ignore the update, at some point of time it becomes necessary to update the BIOS as your computer performance starts to degrade.
How to Update BIOS?
BIOS is a software that needs to be regularly updated just like any other applications and the operating system. It is recommended to update BIOS as a part of your scheduled update cycle as the update contains feature enhancements or changes that will help to keep your current system software compatible with other system modules as well as provide security updates and increased stability. BIOS updates cannot take place automatically. You have to update BIOS manually whenever you choose to do so.
You need to be very careful while updating BIOS. If you just update the BIOS without going through the instructions first then it can lead to several issues such as computer freezes, crashing or power loss, etc. These problems might also arise if your BIOS software has corrupted or you may have updated the wrong BIOS version. So, before updating BIOS, it is is very important to know the correct version of BIOS for your PC.
