Also bear in mind, many newer (i.e. mfg'd within the past 2-3 years) mobos have a flashable BIOS chip, which means that if the problem IS your BIOS, then you won't have to purchase a whole new mobo or even bother with replacing the BIOS chip....
That's what you should inquire of your PC or motherboard manufacturer (assuming you don't already know, of course), and for future reference, make sure you try to get the model-specific information (such as its model #) relative to your individual system &/or motherboard.
If, of course, you already have all of the above info in your possession, then you should try to browse to your system or mobo manufacturer's website, and search for a newer version of your system's BIOS to download and then run the BIOS flash procedure application.
Just a little extraneous FYI.
