Question CPU maxed out while GPU under 10% utilization in game

[dr.mann9356]

I just switched out the motherboard of my system from and MSI z-370 A Pro to an Asus Tuff z370 Plus. Ever since then I've been getting noticeable stutter in the games I play. Upon looking at task manager, my CPU was constantly at 100% utilization while my GPU would fluctuate between 5-2%, sometimes dropping down to 0%. This was in Black Ops 4. I tested playing Battlefield 5 as well, same thing except the GPU got to about 30% utilization in task manager. Any solutions? Thanks.

Specs
Mobo: Asus Tuff z370 Plus
GPU: Nvidia 2070
CPU: Intel Core i7 8700k
Ram: Ripjaws Trident Z RBG (16GB)

What resolution and settings?

Did you reinstall Windows after the motherboard change? If not, that's something you need to do.

I have not. Didn't know that was something you need to do, thanks.

Reinstalling windows after a board change is always a good idea. Additionally go into bios.and enable xmp. Seems your ram is still running at default speeds of 2133.

Nothing is bad out of whack other than the ram.

I suspect the freezing is due to driver conflicts from old os on new board

I've updated all drivers on this system, but I'll do a fresh reinstall of windows and enable xmp. Thanks for your help!

Okay report back when done. Should help most likely

Reinstalled windows and turned on XMP. Still having stuttering and low utilization the GPU though.

Could be conflicting drivers, I didn't delete any when I switched boards.

Probably worth giving a shot

how exactly did you reinstall windows?
using a flash drive?
during the install, did you just install on top of the existing installation or did you wipe all the partitions clean into one empty drive and install on that?
