Question cpu 100 unless i open task manager

[cwjacare]

for some reason my cpu is always at 100 unless i open task manager, someoine help me, idk what could cause this

 

[rgd1101]

did you use anything else other then task manger?
do you have performance issue on the system other than seeing this 100%?

 

[TJ Hooker]

let me see if i made myself clear.
cpu is constantly at 100% usage, always, unless i open task manager it instantly drops to normal.
and yes task manager it is

No, I'm afraid you're not making yourself clear. You claim CPU usage is 100% when take manager is not running. The only way you could know this is if you're using some utility other than task manager to measure usage, and I'm asking what that utility is.

The alternative is that what you really mean is that CPU usage is 100% for the first instant after task manager is started and then drops down, but you don't know what it was prior to task manager being launched. Is this the case?

ive done it twice, and the problem still remains is it possible that the virus went to the usb aswell?

You've 'reinstalled', or, ....deleted existing partition and full reinstalled, including correct installation of all chipset drivers, etc? (short of you promptly reinstalling infected software hacks/patches afterward, very few malware variants survive such a procedure...)

From reading here, it initially sounded like you had malware hiding itself when task manager was opened, the task suspends itself. (Assuming we are not merely chasing momentary spikes in CPU usage that often accompany marginal/botched storage access, although this is more common with spinning drives than with very fast SSDs...)

Use/borrow another $5 USB flash drive at least 8 GB in size, and download/make new WIndows install media on an uninfected computer. Get antoehr flash drive, and , again from an uninfected system, download your chipset and GPU drivers. At least temporarily, do not use any of your potentially infected USB drives or even external drives for reinstallation of any software, drivers, patches, etc... Wtih your CPU and SSD, deleting partitions/reinstalling Win10 should take 5 minutes or less, plus another few minutes installing chipset/GPU driver packages....

If we cannot delete partition/full reinstall without strange/miraculous prompt reinfection (hard to fathom), you might need a competent repair shop's services..

do you have performance issue on the system other than seeing this 100%?

no, its not really performance issue but i notice on task manager its using 36% of memory when im barely doing anything, something that never happened

windows would use ram as cache.
and task manger could be wrong.

hmm well I just gave 430.53 a whirl on battlefront 2 and I got 100% cpu usage for a couple of minutes on startup but that was the game running the prepare shaders for the first time on new driver install after that it was about 80% usage on my fx 4350 @ 1080p dsr with ultra settings on 4k quality directx 11 didn't get any lag so the driver seems to be working for me. On idle my cpu is 2% usage. No evident problem.

Perfect!

If it happens often, that you (or someone else) get trapped in such finicky problems and you are willed to analyze it in a consistent and reproducible manner, you may be interested in:

Hope it helps. Further on ... Thanks for reading.

It's completely normal. My idle memory usage can be 30% but I've got samsung rapid mode enabled for my ssd (with 16gb). You can debloat windows with the windows debloater also follow a guide for optimizing windows services. Though I wouldn't disable windows update or windows defender. You will have to debloat periodically as some bloatware gets reinstalled with windows updates. But you need security updates. I don't usually trifle with it much, as I don't notice anything that's affecting performance.

If there is a real hardware problem the pc would crash & normally I can work out what it is on my system. But it's been running smoothly for years so I don't have to do much with it. The mysteries of event viewer I tend to ignore because it's all to complex though I've made some periodic efforts at looking up the ! red events, I don't get the technobabble! At the moment I've got one yellow application and one red system event a 10016 & I guess that's because of KOTOR 1 being a legacy game I just installed, but it works so the ins and outs of it I would bother with no more and let event viewer complain!

yes that is

Then I don't see an issue. It's normal for CPU usage to spike for an instance when launching an application. My 6700K spikes to ~75% when I launch task manager, then immediately drops back down.
