If you're nervous about updating your bios, you shouldn't be. There are to methods. 1. You can flash your bios, but if it is the wrong bios, you will brick you computer, so I do not recommend that. Even if you do accidentally do that, there is a back up bios that the company of your board can help you get. 2. Get the bios on a flash drive and then do it that way. This is more safer than flashing. Just make sure you do not shutdown your pc during the process. That is all. For the version, just go to google and type in the exact model and make of your board and then it should have the bios you will need. Do not be nervous about it, it will be ok.
