My CPU USAGE fluctuates heavily even when i am doing nothing and computer remains idle.

In the Catalyst Centre under Power i have made it MINIMUM 800Mhz and Max 3200Mhz.

i have done a screen record also:

mR. khool cool Koolent i dont think its a property deal or something, or any kind of race so that you have to reserve your space for your UPCOMING post/reply.Try to make replies only after completing your research work in your dreams.

Stop that absurd act.


@OP.

Install a decent AV like Avast and run a complete scan.
Maybe a Virus.
Or Try MALWAREBYTES for quicker cleanups.

LOL, :p Sorry.. :D but ok, Sorry again.. LOL :D

@OP- Which antivirus you got ?? and though using malwarebytes is also real useful when you don't want to download a huge file :)

There can be a virus or you have more than required amount of applications running in the background, check that up.. :)

@Sujeet: i already have KIS loaded, sigle user single PC version. Full scan not done recently.do i still need to run malwarebytes? if yes where can i get one?


@ Koolent: If more than required applications are running in background where to check and how to stop that? I am also

Seems like a virus. Download any free AV like Avira or AVG and do a scan from safe mode. also try this- HouseCall - Free Online Virus Scan - Trend Micro USA


edit: Also try Malwarebytes Antimalware.

Install Ccleaner and run a complete cleanup.After that remove all unwanted Startup Program entries using Cleaner Utility.
CCleaner - PC Optimization and Cleaning - Free Download

Download Malwarebytes.

this i am not understanding. When i already have a licensed version of KASPERSKY Internet Security 2012 why do i require a free AV.

Again i download HOUSECALL will not get caught by KIS as virus?

This might help...
As far as what I had studied in my Engineering Subject and some extra reading on Operating Systems, it seems that a processor is designed to NOT sit idle,it always has to do some work...hence you always see it range from 20 - 40 %..and its said that for a standard computer that much is normal...processors that are on full load may show 95-97% usage..

Download Process Hacker 2.27

Run it and sort the Process by CPU Usage.
You will come to know whcih process/program is using maximum CPU Threads.

This can be done using Task Manager too but IMO Process Hacker makes the task easier with neat Interface and Tree structured Process Management.

Well it seems its KIS only that is hogging the system during Idle mode.

It must be performing cleanups or scans and thats why The CPU usage shoots Up.

Use Process Hacker as mentioned Previously to confirm It.

I am unable to get whatever you are trying to say.
But anyways take a look at Process Chart(Task Manager) for System while Idl-ing.

What I want to say is that, a processor is designed to make use of all the resources available and to do some work all the time. In the attached image we arent using the computer , but still the CPU usage is 1%.
The Goal is not to let the CPU sit idle...you'll never see a 0% CPU usage..and due to all the background stuff running (like DHCP / DNS stuff, Gadgets, Networks etc.)...the CPU usage is never 0%

Setup will be fine for you.

Ofcourse even a single line of code under execution is bound to use atleast one CPU thread so definitely with so so much background prcesses running CPU usage will never idle at 0%.

But according to OPs problem there is heavy CPU usage fluctuation(check video) and that not common thing.

At idling CPU under normal scenario should constantly float within a threshold range that depends on System Configuration and OS installed

^^ Sujeet is right, the CPU usage is really hard to ignore and that the OP has a Kaspersky, how might it be a virus.. :/.. This is going Crazzy..

Researching more.. :brainiac:

EDIT- @OP Bro, post your CPU temps here.. Let us check once.. :)

Check with root kit scanners and also another AV. Its not like Kapersky detects all root kits and viruses.

I think You should do some searching for yourself.
Will be useful in Long Term:)

We cant spoon feed anyone for every thing.
You gotta do it for yourself at the end of the day.

Google is your best Friend.:wink:

Thanks for the advice.

I return home from office at 12 a.m.and need to take care of my daughter. So i do not get much time to find anything over my 2g speed Internet.That's why just asking for a help from someone who already knows it.

I think I can't post all kind of link here in this forum. ;) Same rule goes for everyone. I think you have understood my point of view.

Now here is the Process Hacker screenshot

according to the video you posted ~29% was the avg cpu usage of the recording process itself.you also seems to be using fancy desktop themes/gadgets which again will eat cpu resources not to mention kaspersky also monitoring such process activities.just try default windows theme with no gadget/sidebar & if still there is high cpu usage during idle time then reply.

process explorer screenshot seems ok with usual cpu usage & processes.

Currently i have only 3 gadgets - System monitor II, Network Meter and Weather.
Changed to Windows classic theme. Now it seems to be within range. but looks like i am using win95.

Everyone wants to make his windows theme a stylish one specially in win7. For that, should cpu usage oscillates wildly.

Hehe.. But look at the poor fellow yar, what if you had to browse at 2G speeds :(..

@OP-I think you should get a new 3G or Broadband.. The 2G life sucks :(.. But I don't think you can post such links here to.. Get th point.. :p

got the point. I have KS TDSKILLER. have run it without any threats detected. Currently running Malwarebytes.

You probably have virus in your computer. I had the same issue before when I was not doing anything at all. Then I used virus scan and computer was full of virus. But my norton was not able to remove it so I reinstall the computer and it is working really well again.

i am using windows 7 aero theme(not basic) with no gadget on an intel atom system with kaspersky 2012 & idle cpu usage is between 1-8%.your screenshot looks like you are using some 3rd party theme kinda like tiles in windows 8.just use aero theme & windows inbuilt/official gadgets(e.g.system monitor is not microsoft's gadget) then see the usage.
