My CPU usage 100% but it I don't know why it's so high?

Question

I'm not a computer person, I just know the basis of the whole thing.
This is my task manager, and I also don't know why there's so many Google Chrome processes- this is how many processes of Google Chrome there are when I only have one page opened up (without going to any site):

And when I click the CPU tab thing, to see what is using so much of my usage, it doesn't come up with anything (like only 3 or 4 things that will be between 02-08).

Is there something wrong with my computer? :s
This is so confusing!

Answer 1

I don't know why Chrome would have so many processes going; likely Add-ins." You can control add-ins from the options menus. I don't typically use Chrome so you're on your own finding that particular option.



When you open the Task Manager and look at Processes you will typically only see those processes that you own. At the bottom left you should see a selection box, "Show processes from all users." Select that one and you should then see all of the CPU processes. Click on CPU to sort them and you should be able to tell pretty quickly which processes are the issue.



Something that you can also do is to restart your computer then look at this list. Check to see, in Performance" what percentage of CPU is in use. If it is still 100% then you may have a virus or some other similar issue. You can get cleaners on-line for most of that stuff.

Answer 2

Many different processes of the same app can be normal. I don't use google chrome so i can't say if it's the same here.



To begin with it's not bad for the cpu to work at 100 percent. A 100 percent cpu usage message means that either the computer is working at maximum speed and probably is slow to respond, or that the message is incorrect, and incorrect messages about cpu speed are quite common. A constant 100 percent cpu-usage may however also indicate malware working in the background. Or it may be for instance that google causes this, so close it and see what happens. You can just keep using google though as long as it works wel.



Normally when the computer is fully booted and idle the cpu usage should be below 10 percent. If at that point the cpu usage is high also you either may have a computer that's way to slow, or you may have malware on your computer, or the cpu-speed indication is just wrong, or legitimate software is using cpu idle-time making the cpu-speed seem to be 100 percent all the time, which may be true in the sense that the cpu might work at the max speed, but also is missleading because only idle time (the left-over capasity of the cpu not needed by other processes) is used and this should be given free for other processes when needed.



To find what causes the cpu-speed to stay at 100 percent unload apps, untill the cpu-load drops. The last app or utility you unloaded wil be the cause. If this is a usefull app you just can keep using it, but then you can't read the cpu-speed and the 100 percent should be ignored. maybe your antivirus is for instance causing it. If you don't want to unload antivirus when online first deactivate your networkcard.



It's always good to have some kind of utility that gives a wel-documented method to manage running processes and services. For windows xp i had such a utility called "the ultimate troubleshooter" ( http://www.youtube.com/watch?v=-KaGBucIjpc ) but it doesn't support 64 bit processes. Ashampoo has a utility called winoptimizer 9 that also has a servicemanager and startup manager ( http://www.ashampoo.com/en/eur/pin/3306/System_Utilities/Ashampoo-WinOptimizer-9 ) , but i haven't used that utility myself. An alternative might be norton utilities. Good documentation is key here to know if you can safely deactivate a process or service. Every running process is a potential cause of a conflict, so not running unneeded processes is a smart move.



It also pays off to have a backup of windows that hasn't any applications at all, but just drivers and windows updates. This way you can try to set up a working combination of applications using the trial and error method. Utilities can only do so much, best result is often achieved by experimenting in this fashion, in my experiance. Note that some types of applications typically cause more problems (i'm not referring to cpu-load here but general software conflicts ) then others. For instance a real-time system-utility like an antivirus-application is typically more likely to cause trouble then a wordprocessor.

Answer 3

You first need to go to windows logo click on it. Then in the search bar type MSCONFIG. right click on msconfig and select run as administrator. once there click boot up tab in that menu click advanced button then under cpu processors select the number of core processors you have in your processor. click out of all that windows will ask for a restart click on yes. As computer is being restarted press the correct key to get into the bois this should be done before windows starts to boot. You can refer to your computer owners manual or your computer manufacturer's website for what key to press to get into bois. Once in the computer bois make sure that the achi has been selected along with the hard drive to be run NATIVE not legacy if the computer is newer. If you have 64bit option in the computer bois and have a 64bit windows select 64bit. Lean thing down while in the bois: 1394 port or fire wire is not really used much any more if you have the option to disable it then do so. If you have a couple different sata port chipsets or variety then disable the one or one's you are not using. There are many more things to lean down depending on the configuration and type of computer that was not in the question being asked. On boot up: The only thing really required is the hard drive. The other things should be disabled These are just a few different things to try from the computer bois to make boot up and computer operation a little more direct. there are also things in windows that can be leaned down. So many and that fact that the computer specifications and speeds were not listed in the question I cannot answer in depth. What I do know is that with Windows and windows updates it's not like updating a graphic card driver to the latest driver because it is best to do. With windows one needs to read each update that the Operating system has to offer and choose wisely. Because of the lack of information in the question. I could see this system to be a victim of too many windows updates as well as a possible virus.

Answer 4

The many Google Chrome processes could be due to a previous session which maybe didn't close properly or something. Just try ending all of those Google Chrome processes - it should lower the usage. Otherwise, you might have too many other programs open and running - try closing some of them. Restarting the computer might help as well.

Answer 5

You might have a lot of programs. Try deleting some. It's different depending on what type of Windows you have. On Vista and 7, you can go to Control Panel, Classic (which will be on the left), and something that says something similar to Uninstall Programs. Click on that and it's pretty obvious from there.

Answer 6

Well

In my opinion Ccleaner is the number one tool for cleaning your pc. I've been using it for more then a year now and it works very well. You can grab your free copy here http://j.mp/UrACoa

I strongly recommend it.
