In most cases, nothing will go wrong at all, but it's important to know that there's an associated risk and not to treat the process too lightly.It's good to have a spare copy of all important files from your PC before you start.If you do not encounter any system instability or bugs with the current BIOS version, we suggest that you keep it.If you determine to flash BIOS, you are taking a personal risk of BIOS flash failure.
Please visit your motherboard manufacturer's website for instructions on how to check your BIOS version and for tools you can use to safely update your BIOS.
If not, there may be little point in taking the risk by updating.
Sometimes you will need to update the BIOS in order for the motherboard to properly support a new processor or other hardware, or to fix bugs and improve stability or performance.
Sometimes this will be done automatically as part of the updating process, but if it requires you to do it manually, be sure not to skip this step.
If everything applies, upgrading your BIOS is likely a worthwhile idea.
For this reason, it's worth checking whether you really need to update your BIOS.
