It is running (original) BIOS F.24 11/25/2008. I found BIOS V.66 A 05/31/2010 from HP support website but it says PC should be running Vista or Win7. This PC was shipped with Vista but I upgraded to Win8 (clean install). Is it okay to upgrade BIOS? What does Windows version have to do with upgrading BIOS? Will it brick?
