Walk me through bios update?
On your computer search, search msinfo32
It will say your motherboard version there. Google that plus "support". Go to the bios downloads page. Download it to a USB on its own (unzipped file) . Boot to bios (refer to your motherboard manual, usually its f2 or f10 on startup). Find the update bios option and navigate to file on your USB.
After that I'd revisit that page and download drivers for your chipset.
