Unexplained activity in the use of the processor in the Task Manager

I am running Windows XP - sp3 in a laptop that works exceptionally well.  When I go to the Task Manager with no applications running and is connected to the network or not (no network activity).  The cpu usage graph use of 28% of all 15 seconds.  This has no effect on the operation of the units. I use Microsofts antivirus app, and there is no trace of any other anti-virus program. I scanned for any viruses or malware and clean air unit.  I would like to find out what is causing this cyclical use of CPU.  Is it possible to find out.  Thank you.

  • View Manager does not load at startup (Windows 8 - confirmed activated in the Task Manager / start)

    During the recent update MDD, I can't get it to load automatically at startup.

    I am running Windows 8.1.

    I have to run it manually every time that I boot - which is a pain.

    I activate under via Task Manager startup items (oddly there are two DDMs that appears here, both are enabled).

    Any advice / help?

    Thanks in advance!

    It seems that you have installed the display manager Dell with privileges "Run as administrator". DDM cannot load automatically with this option for reasons of security, that is, it cannot start without the explicit permission of an administrator - Windows does not.

    Right-click on the MDD program or shortcut and select Properties, then cliquer click on the Compatibility tab, uncheck the box "Run this program as Administrator" and then click on "change settings for all users.

    Or just reinstall it with the "Run as Administrator" option unchecked. DDM itself doesn't require elevated privileges.

  • After the installation of 5.71 Lightroom it runs only in the Task Manager

    Hello

    I currently have a problem with Lightroom 5.71/windows 7 / 64-bit. After starting the program it is only being showed in the taskbar and the Task Manager. There is no error indicated by the program.

    I had no problem with the previous version 5.70.

    Thank you in advance.

    How many monitors are connected to your system... and how many monitors is your operating system, think THAT are connected to your system.

    If it shows as active in the Task Manager and the taskbar, it is possible that it is opening on a second monitor assigned. Right-click on an empty area of the desktop, select the screen resolution... how many active monitors show (highlighted in blue)?

  • All of the physical memory used, but nothing in the Task Manager

    Hi I have windows 7 64 bit new installation as of yesterday (fully updated) and encounter a performance problem. When I look under task manager 95% of my physical memory (4 GB 3.5 GB) is used, but there is no task that uses memory. I chose to see the task for all users, and again nothing use the 3.5 GB of memory. It is a pretty clean install (auditor of virus and Skype, installed steam just) so no chance of a virus. I check my page file and it is set for the page file windows automatically scabies.

    I tried many things:-all service stop I can (no change)
    manually configure the paging file (no change)
    Reinstalled windows 7 (problem is finally once that all updates have been applied)

    Any help is greatly appreciated.

    Thank you

    I had the same problem and it is solved.

    a month ago my computer was sluggish and his memory was 77% either 93%, even though nothing was running. in the Task Manager for all the different processes added up to about 1.75 GB, so there was about 2 GB memory unexplained (4gig memory). I always ignored the 'show processes from all users"because im the only user on my computer, but decided to finally click i and a new process comes top of the list. Windows Media Player Network Sharing Service, this process itself was using 2 GB of memory. After completing the process, my memory returned to normal. However another thing you need to do is go to the resource monitor in the performance of the Manager section tasks and to suspend all processes of Window Media Player Network Sharing Service which are still open to slow things, and then set your very pretty.

    I realize that this is maybe not the exact answer to problem for everyone, but give it a shot.

  • I was just wondering if raising the Task Manager causes a spike in CPU percentage used? What is the normal percentage?

    I was just wondering if raising the Task Manager causes a spike in CPU percentage used? What is the normal percentage?

    Original title: percentage of CPU

    ASJ

    I guess it depends what you mean by 'raising '.  If the Task Manager is running minimized and you maximize there should be virtually no effect.  If you ask any Manager launch tasks can be a brief rally in cpu, memory, and HD activity, but he should be back almost immediately where he was, the slight increase depends on your specifications of the system and other factors.

    Is there a reason you ask?

  • No start page, Google rises and there is no way out without using the Task Manager.

    I used to get the Google search engine at the start of Firefox, with bookmarks bar in side bars and tool at the top. Now, all I get is a Google search page, with a few buttons on the top like images, etc. There is no way to close the program without using the Task Manager. I downloaded the latest version of Firefox and installed, but the problem has not disappeared. Operating system is Windows XP Professional

    Make sure that you run not Firefox mode full screen (press F11 or Fn + F11 to toggle; Mac: Ctrl + Shift + F).

    It is possible that the screen is too wide or too high and bars scrolling down.

    • Use Restore or expand in the context menu of the taskbar icon to set the focus to the Firefox application if you do not see the window of Firefox.
    • Open the system menu of the window of Firefox via Alt + space and see if you can move and resize the window (use the arrows on the keyboard).

    If it works, then first close all other open windows of Firefox and then close Firefox via "file > exit/Quit" to save the setting.

  • When I used to hit ctrl, ALT, delete, Task Manager appears. Now, just the screen CPU usage. How can I get that back for the bigger task manager, which, the CPU usage was a tab to the breast? Thank you.

    The Task Manager is now just 'CPU' because I must have hit something wrong.  I was hoping just to click on the tab use the CPU in the Task Manager, now somehow when I hit CTRL, remove alt. it shows only the CPU usage graph.

    Double-click the window border.

  • My CPU usage is at 100%, but the task manager says that nothing is more than using 01%

    Last night, I installed the updates for Windows 7 during the stop, as I normally do. He said there are four updates, and one went by pretty quickly. It seemed to get stuck on the second (even though he probably didn't want to - the blue ORB turned and the dots are moving, so I guess it's to large or slow) for a few minutes, three update took slightly less time and at the time he obtained for the release of four, I was paying attention just because I was so tired.

    In any case, I went to start my laptop (Toshiba Satellite) and on black splash screen "starting windows" with the flag/banner, he said that he needed install/configure 360 some odd updates. I had seen this before, although I do not remember how recently, so I thought nothing of it. I still don't know if it meant something significant.

    Now the problem is that my CPU usage is constantly at 100%, yet when I finally managed to open the Task Manager, NONE of the listed processes use anything more than 1%, and those who fluctuate. I can easily boot into safe mode, and from there, I have disabled the start of the process, such as taskbar support and itunes things google related, but I still boot normally to 100%.

    Any ideas? It would be GREATLY appreciated. I'm going to College next year and I really don't want to worry about finding how to get a new machine.

    Thank you!

    Hi Renae92,

    1. You have security software installed on the computer?
    2. High CPU usage occurs after the boot process?

    Method 1

    As the problem does not persist in safe mode, then it is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you put the computer in a clean boot state and check.

    To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See section to learn more about how to clean boot.
