How can I maintain a consistent CPU usage?

John February 15, 2011

When my Windows computer is being used for a certain period of time, the performance of the operating system slows and the CPU is being eaten by some process that was opened for a long period. Is there a way to keep processes from consuming more and more resources as time passes? Thanks.

    Hello, have you tried process explorer? Process explorer is a free program that can provide you with information about what processes are open or loaded on your system. Process explorer also includes a search option that will show you which processes have particular handles opened. It is more advances and provides more options than viewing the processes through task manager. Here is the link:

    Another reason that your computer might be slowing down after using it for some time is the amount of memory you have installed. The way computers work is that when your physical memory(RAM) is used up, it uses your harddrive as memory. This memory is called virtual memory. Usually the virtual memory is set at 1.5 more than the ram installed. If you have 1 GB of memory installed, your virtual memory is automatically set at 1.5 GBs of virtual memory and so on.

    As you can see, the more RAM you have installed, the better it is for your system because then you will not use too much of your virtual memory. Hard drives can never be as fast as RAM (except solid state drives), that is why when all your RAM is used up, you feel the system slowing down because it switches to use your virtual memory. Hope it helps.

    If you want to find out the amount of virtual memory on your system, do the following:

    -- windows key + Pause/Break key
    -- Click on Advanced Tab
    -- Under Performance heading click on Settings
    -- Click on Advanced Tab
    -- Look under Virtual Memory Heading

    Hope it helps.

    Ram adjustment can help, look for ram optimizers that will clean your ram. But as always those process that will need ram they will take it back. This can help if a closed process was not closed well and eats ram.

    Which processes are utilizing all your system ressources?

    There are various reasons why this may happen. For example it could be some indexing process or so which was waiting in the background or maybe some wrong configuration or setting that is causing a Windows service or process to spike.

      I'm not sure which processes, generally web browsers like Internet Explorer who have the tendency of consuming more than average resources. I'm not familiar with which processes could be consuming the share of resources, but I kept noticing that computer usually slows after period of time, like watching videos, creating movies,....etc.

      I'm not sure if computers behave in this way.

        To see which processes are using up your ressources you can look into the Task Manager.
        You can open it by right-clicking on the Taskbar and select Task Manager or by pressing Ctrl + Alt + Del and then select the Task Manager.

        There are also alternative tools to get a look the processes running on your system.!5378494/five-best-windows-task-manager-alternatives
