Putting a 7700k in an msi z170 a mobo

[Nimblewhale]

So I wanted to switch to Intel and was gifted a brand new msi z170a and when it came time to buy a processor I went with the 7700k. After assembly the computer stays on but the screen remains black. Apparently I need a bios update for my mobo but don't know how to get one without having a cpu. What should I do? Should it be working and I did something else wrong?

You need a skylake CPU to do the bios update. Either send the 7700k back for a 6700k, buy or borrow any Skylake processor and update the BIOS, or eBay the board and buy a z270
