ASUS H310M-A

A friend of mine decided to upgrade his processor from an i5 to i9 9900k, gave his pc over to his local PC store who installed the cpu on the asus board and told him it didn't work. I checked on Asus website and according to MB spec, a Bios upgrade was needed to allow the new CPU to work. I updated the bios and reinstalled the i9 chip and it still doesn't work. Any thoughts?

Madness springs to mind. The VRMs are going up in smoke sooner rather than later if you put any load across all cores/threads. It's not the right board for a 9900K.

That said, if you just want to see if the 9900K works, or if you want to take a gamble using it on that board (at least stick a fan blowing on the VRMs), try taking out the battery for 10 minutes. While the battery is out, take the 9900K out as well, and look carefully for any bent pins in the socket. Also look carefully at the underside of the 9900K to see if there's the slightest speck of dust/paste/whatever on one of the gold contacts.

Words coming to my mind are "fire waiting to happen": That VRM without any slightest heatsink would be questionable even for i5.
(+Paying super high end price for yester-yesteryear's stuff: Price of that CPU would have gotten 8 core/16 thread CPU+mobo with actual upgrade path)

And remove name of competitor, those aren't allowed.

He is purchasing a new MB, all this says to me is The guy in the shop who was installing his upgrade parts ain't got a clue what he's doing!
