You will have to go to Acer's website for your computer, find the latest BIOS, and then follow their instructions.
Acer seems not to permit direct linking. Go to:
http://www.acer.com/ac/en/ID/content/drivers
group Desktop, series Aspire, products Aspire M3910.
The BIOS download is a .zip file. Inside it is a document that tells you several ways to update the BIOS. I guess that you need the Windows X64 method.
A warning: it is unlikely, but not impossible, that trying a BIOS update will render the machine unbootable. I think that the EEPROM chip that contains the BIOS is soldered to the motherboard, so fixing that may not be simple.
Why do you want to update your BIOS? Is there something your computer doesn't do that the a BIOS update indicates that it will fix?
Thanks everybody for the help!
