I built my comp last summer and I have not updated the bios sense then. I have never done this before and I am wondering if it is more involved than a regular driver update. I went on ASUS website and I got this info when I put in my mobo info.
It isn't too involved. However, I wouldn't suggest updating the BIOS unless something is wrong. If something isn't wrong, don't fix it. That is, unless you are aching for something to do..
