Games take up 100% of the CPU

[Aluttrell]

In the last few days I have noticed very poor performance from my CPU. Games I used to be able to run smoothly are now lagging and when I looked into the task manager, I noticed than anything that is running in the forefront take up more CPU usage than is normal. If I run a game, it immediately uses up what's left of my CPU putting my total usage at 100%. It's not svchost.exe or anything else. Also I noticed really bad lag when moving my mouse that was set at 1000Hz polling rate, which is what has always been at. If I move my mouse the CPU usage skyrockets, even with it set to 250Hz. There was a recent power outage and I fear that it may have damaged my CPU but I'm not sure. It didn't start happening until then. Is this a possibility or could it be anything else? I've check all over the internet for solutions but no one has had anything related to my problem. Again, anytime I run a game it uses all of my CPU. It's never just one process that's eating it up, it's all of them. Nothing else is struggling on my system. GPU is fine, RAM is fine, HDD is fine. I'm considering a reformat because I'm having another Windows related issue, but that issue doesn't have any relation to this one.

Specs:
CPU: Intel i7 7600K
RAM: 16GB (8 x2) Ripjaw DDR4
GPU: Gigabyte 1070 Xtreme Edition
PSU: Cooler Master Silent Pro M2 720W
Motherboard: Gigabyte Gaming K5 Z270 Aorus

What is the cpu temp? and freq when you game?

Frequency is 4.2GHz (stock for the 7600K), and temps never get above 60 C. I have the Hyper 212 EVO that keeps it nice and chilly

Open up task manager and run through everything and see what's running and what's using cpu %

As I said in my OP, it's the app that's running in the foreground. I believe the issue is with my motherboard.

Any fix? Im having the same problem with an i5 7600k... to be honest from what I've seen, everyone that's had to problem and reported it on reddit or this site has a GTX 1070, no clue if that's something to look out for, but my pc was built a week ago, ran fine the first 3 days crystal clear, and now has high cpu usage

If you've had any windows updates when this all started happening, it's more than likely 1 of 2 things. Either you'll need to do a clean install of the nvidia drivers or you'll have to do that as well as updating the motherboard drivers. Recent windows updates have played havoc with some versions of nvidia drivers, especially when the Creators update finally gets downloaded. It can also affect lan and Realtek audio drivers if you have them.
