Unusually High Usage on I7 6700K

I just built a new system on the i7, and whether I'm opening Chrome or playing any game, CPU usage on my 6700k skyrockets and it makes things unplayable with framerate drops, hitching, and mouse lag. I've been testing for the skylake bug with prime95, I've updated my bios, and I've made sure all of my drivers for everything else are up to date. Nothing has helped.

My build:
I7 6700k
ASRock Z170 OC Formula
16Gb G-skill 3400 ddr4
Zotac 980ti Amped Extreme
1000w Rosewill PSU

More about unusually high usage 6700k
  1. What in particular is using all of your CPU cycles? What does task manager report as having high CPU usage?

    Have you checked to make sure your CPU is clocking up to ~4ghz correctly?

    it seems to be whatever is the main process. Opening chrome spikes it to nearly 90%, and in Witcher 3, Battlefront, BF4, The Division it just spikes constantly. When nothing is running in the foreground the only thing that really uses CPU at all is the desktop window manager or WMI Provider Host and they usually never pass 3% at most.

    Task Manager says it's averaging 4.10ghz. (it's not OC'd)

    What motherboard do you have? Is the BIOS updated?
  4. Yeah I made sure the bios was up to date before I installed the OS drive again.

    I'm starting to think the problem is the OS. It's pretty overloaded at this point on a 120gb ssd and I just did a complete switch from amd/ati to Intel/nvidia and I think it may have just been a system shock. I'm going to get a fresh install of w10 on a new ssd and see if that does the trick.

    If you change sockets, you definately want to do a fresh OS install. Even if you upgrade a processor with the same motherboard it's better to be safe than sorry, but there are a lot of people that say they've never had a problem, but in your case it's a completely new system as far as the OS is concerned, so yeah, try a fresh install!
