The Optiplex 3010 originally came out in 2012 and is basically considered obsolete. However, you can still find drivers and BIOS updates for it. Go to Support -> enter Service Tag # -> Drivers & Downloads -> Manually download. There you will find the latest updates. I have a 3020 which had a really old BIOS, so what I did was incremental updates. Went from A05 to A07 to A10, etc, up to A20. That's usually the safest way to update an old BIOS, after reading some older posts on here. 
I have an Optiplex 3010 but that number is not listed in the 3000 series of choices. How come? I often get emails from DELL that a new BIOS update is available and since I am not having any specific problem, I am reluctant to perform the BIOS update. My question is has anybody done a BIOS update and bricked their PC like it used to be known to do? Also, what's with the incomplete '800' numbers listed on this page:[URL] Thanks in advance to all who reply. Dan
