To your first question, the risk is minimal. The install is pretty user friendly

In order to answer your second question I will need to know a few things

What is the make and model of your PC?
How old is your PC?
What BIOS are you running now?

Hello azetect and welcome to PCHF.

A BIOS Flash which is what it's called is not to be taken lightly.

There is always a risk factor and if you do it wrong you can end up with a non functioning motherboard.










From Wikipedia, the free encyclopedia



In computing, the BIOS (pronounced /ˈbaɪoʊs/) is an acronym that stands for the Basic Input/Output System.
BIOS in part refers to the firmware code run by a PC when first powered on, which is a type of boot loader. The primary function of the BIOS is to identify and initialize system component hardware (such as the video display card, hard disk, and floppy disk) and some other hardware devices. This is to prepare the machine into a known low capability state, so other software programs stored on various media can be loaded, executed, and given control of the PC.[1] This process is known as booting, or booting up, which is short for bootstrapping. Among other classes of computers, the generic terms boot monitor, boot loader or boot ROM were commonly used. Some Sun and Macintosh PowerPC computers used Open Firmware for this purpose. There are a few alternatives for Legacy BIOS in the x86 world: Extensible Firmware Interface, Open Firmware (used on the OLPC XO-1) and coreboot.
The BIOSes of IBM PC class machines can also be said to be a coded program embedded on a chip that recognizes and controls various devices that make up x86 personal computers, and provides a small library of basic Input/Output functions that can be called to operate and control the peripherals such as the keyboard, primitive (800 x 600) display functions and so forth. Computers designed to run Windows ME or Windows 2000, or later, supersede this basic monitor functionality by taking over direct control of the interrupt table and replacing the monitor routines with faster and more robust low-level modules that, unlike the BIOS function set, are re-entrant. Various BIOS functions in ROM were left in control in earlier Windows versions, and the BIOS only comes into play today in the alternate shell Cmd.exe, or if the machine is booted into a legacy DOS version.[citation needed]


In order to help with locating an appropriate BIOS it is a must to know exactly what motherboard you have including revision or make and model of computer if factory built.

If any of this is intimidating then I would caution you to be very careful before undertaking such a task.

Generally a BIOS is only flashed for a reason such as a fix for some problem or hardware compatibility.




*ETA: Sorry pokemasterflex I was compiling a post and didn't realize you'd responded.

my pc is 2 year and 6 monts old..

my pc spec on this picture

thanks for quick reply

thanks LoneWolf for bios info...

if i restart or reset my bios will there lower risk than upgrade my bios?

I'm not quite sure I understand what you are asking but the BIOS starts every time you turn on your computer it's just that you don't see it unless you enter it by hitting the "delete" key several times.

There are settings in there that can be adjusted and sometimes if a person makes a mistake there's an option worded something along the lines of "load default" which puts things back to a state where it will run safely but sometimes require a bit of tweaking to run optimally or to enable some features to function.

For example if you have onboard sound you could disable it in the BIOS and use a sound card instead. The same with video where some have it built in but people prefer to use a better grade add on video card in which case they'd disable onboard video.

I'm still curious as to why you are thinking about this? Do you have some sort of problem with the computer that you hope to cure?

Going into the BIOS and setting it to default is relatively safe but if you go in there and make changes the motherboard doesn't like then at times the only way back is to clear the CMOS and start with default settings again.

i thinking about this because my computer not running correct way when i 1st bought...because i have some aplication cannot install after my 1st time format my pc also some of my pc backup files on my external hard disk cannot use any more...

maybe i need to reset my bios...what will happen if i reset my bios ?

also how many percent of the risk if i reset my bios ?
