Question i want to update my bios but how do i do

Before you update a bios, there should be a good reason to do so.
A failed bios can brick your motherboard.
This can happen if there is a power failure during the process.
Or, if you stop the process because nothing seems to be going on.
A flash may take 10 minutes with no activity evident.
