I Upgraded my BIOS from A02 to A11 and alot of things don't work right, my printer, my scanner, and I keep loosing all my memory. Every thing worked fine before. The only reason I did this was because I was having screen problems and tec support said to try this. Is there any way to go back to my old version, I have no clue on how to do this if it is possible. I have the Inspiron 8200. I hope someone can help. Thanks
