cpu 100% usage Cpu 100% nothing running!!?

[Neerup]

my task manager shows CPU as using 100% utilisation even though nothing i running, it even shows 100% when i first boot it up, i have literally tried everything including updating bios and resetting windows. pls come with some suggestions.

i use i9-9900k and the reason why i clocked it at 3.6 is because i thought it would solve the problem.

Well... what's using the CPU?

In the processes tab, what does it say?

its random, it depends on whats open, if i have nothing open task manager is like 50%, then if i open google that might go to 80% and task manager is 5%

Windows does a BUNCH of stuff when it first boots up that takes CPU power.  This is normal.

AS stated above, I'd check to see what processes are running.

its not only when i boot its always and the things taking up cpu switch randomly

Some Possible Fixes:

~minimize programs that auto run when you turn your computer on
(seems like you are running blizzard updates and the steam client at the same time)

~run msdt.exe /id PerformanceDiagnostic  and adjust performance that way

~ run services. msc and turn off superfetch

good luck

Do a virus scan, just to make sure nothing is out of the ordinary.

By "resetting Windows", do you mean using the Reset feature?

 

Because I'd like to see what Task Manager is showing the moment after it's done with the Reset, before you install anything.

so i reinstalled windows completly cleaned the drives

Have you verified your temperatures? you could be thermal throttling a lot... Task Manager isn't reliable to see frequencies either so you could be running at a very low frequency due to poor thermals causing the higher CPU usage.

Your pictures in the previous post show otherwise. Pretty sure Windows doesn't come with Blizzard's software, Gyazo, or Chrome.

 

I want to know what it's doing on a completely clean slate, before you install stuff on top of it.

so when i first booted after reinstalling windows completly i checked task manager and the cpu was 100% it was showing that task manager was like 50%, and other normally things was weirdly high

at times task manager will take up a bunch of CPU so it can run overtop other things. It will go down once it sits adle for a bit. Check CPU temps and make sure the cpu is working 100%. Seems strange a 9900k is having issues with windows if it is brand new. Was Windows reset using its built in function or was it installed new via USB/CD?

ive had this pc for like a year now and ive just recently got this problem. ehm so i reset windows a few days ago without luck, not with usb or cd but through the already installed windows

[Touch My Hamm]

Try installing new via USB/CD installing latest drivers and such. Is your performance being affected or is it a visual 100% being shown? Could be some weird windows left over saying its taking power when its not. Or it could be something going on with your processor. Might try reseating it and applying new thermal compound and reseating cooler. Make sure the motherboard sees the correct processor and that all cores are working.

Didn't spike to 100% until the last 5-10 minutes. Looks like if was on for 2 days before the cpu usage jumped.

The graph only shows data while it's open, so that screenshot could be of the last 10 seconds or 2 days.

my performance isnt affected, would it make a big different to install via usb tho? cause i just sat everything up again
