hey thanks man i thought that would probably easiest way but the computer store have been shut down thanks man ill try this as soon as possiblySure, that mobo supports 9th gen, but it doesn't mean jack if the needed bios isn't already uploaded, and there's no way for you to check it either.
Options:
1)Take the PC to a PC shop - if nearby - and ask them to update the bios for you.
2)Acquire an 8th gen cpu to update the bios with.
3)Return the H310-Plus and get a B365 or Z390 instead. Those are guaranteed to support 9th gen out of the box.
