The other night I was installing my new cpu (i9 9900k), coming from an i7 8700. I knew that all of the hardware in my system was listed to be compatible with this upgrade so I just made sure I got the latest BIOS update and completed the install. However, for some reason after switching to the i9, my computer refuses to fully boot into windows. Everything inside the PC powers on, all fans and lights come on but there is no signal to my monitors or keyboard and mouse. The motherboard (MSI z390 Gaming Plus) led debug light becomes stuck in an alternating loop lighting up for CPU then for DRAM and just refuses to boot properly. This is when attempting to boot with dual channel RAM (Corsair Vengeance RGB DDR4 16gb 3200MHz), however, when I try to boot the computer in single channel (1-2 setup instead of 1-3 or 2-4) with both RAM sticks in or even just one, the computer boots up fine and shows zero problems except the RAM of course not being in dual channel. Things I have tried include using two brand new memory sticks (3000MHz same model), resetting BIOS with CMOS battery, making sure my heatsink is evenly tightened, enabling and disabling xmp, increasing voltage to memory.

If there is anything that I can try to help my situation before I resort to buying a newer motherboard, please let me know!

Full PC Specs:

CPU: I9 9900K @ 4.8 GHz

Mobo: MSI Z390 Gaming Plus

RAM: Corsair Vengeance RGB 16gb 3200MHz

GPU: EVGA RTX 2070 XC

PSU: Corsair RM750w

Sounds like a problem with the CPUs memory controller with one of the things that can upset it being the heatsink applying uneven pressure atop of the CPU.

What is the brand and model name or number of the heatsink that you are using.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

First thing we must do is get the legalities out of the way;

Operating System
Windows 10 Education 64-bit

Can you let us know how you come to have an education version of Windows on a personal gaming spec computer, an OS that is well out of date and shown to be having issues as well.

Looking at just anything that could affect your hardware;

Power Profile
Active power scheme: High performance

Change the Windows Power Plan to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues and the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.

Memory
Type: Unknown
Size: 16384 MBytes
Channels #: Single
DRAM Frequency: 1600.1 MHz

Manually set the RAM to 1333MHz and 1.35V in the BIOS

Test the CPU using the tool from here

If the CPU passes all tests pain in the proverbial to do I know but you will have to swap the i7 8700 back in for testing purposes.
