Typically what you can do is boot into your current BIOS and look for a version number. Then locate the support page from the company that manufactured your computer, you'll have to know your model number. Look for a section where you can download support files, and see if there is a BIOS revision posted. Depending on your specific situation, there may not be any bios revisions. If there is a BIOS file, look at the version number and compare it to the one you currently have, if they are the same then there is not an update. That being said, there is always the chance that you may brick your motherboard in the process of updating. You'll have to weigh the benefits and risks of such an operation. This is especially true if there are hard drive problems already, if it hiccups in the process all may be lost.
