It sounds like you have never flashed a BIOS before, its not as scary as you might think. If you take off the side panel of the pc you should be able to see the bios version written on the motherboard. Go to the Motherboard manufacturers web site and find the most upto date bios version. After that you can download the bios file(and probably rename) copy to a Pen/thumb drive and install, usually there is a usb port designated as a bios flashback port, not sure what board you are using but a 14600kf should have a bios flashback facility.
