I have an Acer A315-51 laptop. I am planning to upgrade to an SSD and max out the memory when I replace the dead battery. My computer is running an Acer OEM version of Win 10. I am planning to buy and install Win 10 clean. There is a BIOS update for my computer. Should I install the BIOS update now, before the upgrades or wait until after the new SSD and Win 10 install? Also, how much memory should be allocated to a clean Win 10 install? New SSD is 250 GB. I have a NAS for storage that I dump my computer into as the HD fills.
