I need to get into my bios to do a bios update. I have a gigabyte b360m ds3h motherboard. Whenever I push del, while in post, my screen just stays black, neither bios or windows boot. So then I tried going to bios by going through uefi settings in windows, and same thing, a black screen. Also, this is a fairly new PC, and I haven't entered the bios since I installed windows. Any help would be appreciated.
