I still advise you go into the bios first & perform the Save custom defaults step. After that boot into Windows & double click on the downloaded file to extract the contents. When the files have extracted, double click on the setup.exe file to run the update. Again, do not interrupt the process.
Bios updates always carry an element of risk, you're right. However, the risk in mimimal & if your board is being so problematic that you were considering replacing it anyway, then you have very little to lose.
