High cpu usage - CPU Spikes when moving mouse...

Hi everyone - I've built my own custom pc, it has worked wonders for about 2 years now.

I've rebuilt some of the pc because of upgrades, so my current specifications is as follows...

I7-7700k (I JUST replaced this 2 hours ago more on this down below)

Asus strix 1070 oc

2x 2400MHz 8GB ram Corsair Vengeance

Corsair AX 860 PSU

Asus Maximus VIII Hero Motherboard.

I have had some problems with my old PCU (I5-6600K) where it had high cpu usage, literally spiking from 10-15% idle to 60-70% just by hovering over icons on the desktop. Also running a steady 100% whenever
I used any programs.

Did a bunch of testing to figure out what was wrong with it, but gave up in the end after about 8-10 hours of work on it. Decided to buy a new CPU to see if that helped (i already wanted a new one so i thought
why not...)

The problem that is happening was not persistent after I put the new cpu in today. But after about 2 hours of run on the pc it began having troubles again. It first began while playing world of warcraft. The
FPS was lowered even though both cpu and gpu was running on about 50-80% power. Whenever i would move the mouse my game would just lag out and if i kept moving it continuously it would completely stop showing frames and just freeze until i stopped moving it
again.

After that i noticed that whenever i moved my mouse on the icons on the desktop or move my mouse around on google chrome it begins spiking up again like last time. Also it uses a lot of CPU power for small
jobs which it really shouldn't. Like having discord, 5 pages of chrome and steam open it can use around 30-40% on a i7-7700k??

I know you like when people try to do it themselves first. And I am not a 'noob' at troubleshooting and googling my way through problems, but this one is a tough nut to crack.

Problem: High cpu usage overall and high cpu spikes whenever i move the mouse. Literally can't play games because whenever i have to move the mouse it begins to do lagspikes.

What i've tried so far:

• Reinstalled windows 10 3 times and updated all drivers afterwards.
  
• Wiped the entire SSD with the windows 10 and the games on twice.
  
• Reapplied thermal paste and even replaced the cpu to a newer and stronger edition
  
• uninstalled various drivers from the device manager and reinstalling them.
  
• Fiddling around in safe mode without much knowledge of what to look for.
  
• benchmarked the cpu to see if it was lacking behind (it wasn't)
  
• Done a malware system scan through malware bytes
  
• Done a ccleaner scan
  
• done a antivirus scan through avira.
  

I am out of ideas and i cant seem to find any help on google and i really hope any of you guys are able and willing to help me with this pesky issue... It's not fun to have a 'strong' computer if it can't even
handle browsing or simple games...

 

True core and memory clock on my GFX...what should I trust?

i have the list of nvidia core and shader steppings if you like, it shows the requested clockspeed versus the effective clockspeed.

 

moving mouse cause high cpu usage for explorer.exe

I have the exact same problem. If i move the mouse fast enough CPU usage spikes. I'm assuming its 1903 related

In fact a few processes in task manager are using an abnormal amounts of power.

Hello, can any person confirm they're experiencing the same problem, high CPU usage while using the mouse on explorer.exe process

When the mouse isn't in use nothing. Now i can feel stutter in game. I have two monitors and can see the whole system isn't right. Any suggestion?
