Very risky. Only do it if you really need to. Most people just think it is a little update to the OS, but it is much more that that. It controls what happens before the operating system loads as soon as the computer switches on, "Hello, do we have a hard drive here, do we have memory, is there a video card here somewhere, is the fan working, can all you components talk to each other"? Then is says "okay, lets see if we can find the operating system and load it in the right order"? If the BIOS Update fails, none of that happens and you have a dead computer. I have only done it once in 30 years of computing, including building my own computers.
We really need FULL make, model, BIOS versions and Operating System in such questions. Our computer Guru Larry will be along soon to have a chat with you about that :>)
