[SOLVED] CPU + Motherboard Compatibility.

Solution
The Intel B150 motherboards only support the 6th and 7th generation Intel Core I-Series processors. The 9th Generation Core I9-9900K is NOT supported.

Look at the Gigabyte website and check the CPU compatibility list...it often changes with BIOS updates.

Looking at your motherboard I would guess it does not support the i9 chips...the board has a rather weak VRM design and the socket is not the right version.
