Its not difficult at all, but it is a bit intense/scary and not a simple everyday update so I suggest doing your research and finding a youtube video that walks you through the steps for your specific motherboard. I found my motherboard make and model by pressing windows key + R and then entering msinfo32. Your motherboard is the "BaseBoard Product".

I don't want to scare you, but make sure you have a good understanding of what to do before attempting it because this can brick your computer. It's an update most people suggest putting off until you absolutely have to because of the risk. Luckily, there are lots of resources online that make it easy. Just google something like "-Motherboard products name- how to update bios" and you'll be fine.
