How come my Windows computer sometimes is slow?

melinda February 24, 2011

Sometimes my computer is fast and other times it is slow. I have done all of the scans and disk defragging etc. I have a Gateway laptop that I just bought last spring 2010.

    Hey Melinda,

    Were you able to find out why your PC acts slow sometimes. If you're trying to speedup your Windows system check out following MakeUseOf guide on the subject.

    Hello, your computer can become slow when you have used up all your physical RAM. How much RAM (memory) do you have installed on your system? The reason for this, is that once your computer runs out of physical memory, it turns to using space on your hard drive as virtual memory. Unless you have a ssd (solid state harddrive), your harddrive cannot be as fast as memory. Also, it depends on what operating system you are running. For example, vista is known to be a resource hog. Windows 7 is better when using resources. You can help this situation a little bit if you installed more RAM. The graphics card on your laptop, does it use shared memory? or is it discreet? If you have onboard memory it uses shared memory to work. That means that if you do not have a lot of memory, your graphics card shares that memory with your system. If you have a discreet graphics card, it is better because the graphics card uses its own memory instead of the system's.

    There are other factors that can influence your speed. When you notice that your computer turns slow, what are you doing when that happens? Are you using resource heavy programs like video editors, CAD programs, etc.? The other factors have been mentioned already, like how many programs startup with windows, how many processes, etc. Make sure you keep your computer clean and also make sure that you use programs like Revo Uninstaller to uninstall programs.

    If you uninstall programs, sometimes there are entries left over on the registry. This also affects your speed because your operating system looks for those entries and if it finds them, it loads them whether there is a program to use them or not. Hope it helps.

    how programs are starting at startup(start?run>msconfig)?
    What firewall and antivirus do you use?
    Your windows OS version?

    your hard drive is overloaded. you need at least 10-15% open on it.
    Make sure your drivers are up to date
    do registry cleaning i recommend OptimalPc

    Do sfc, /scannow , go to run they type cmd and rightclick on it to lanuch as administrator then type sfc, /scannow.

    Also do a chkdsk repair on the command prompt type chkdsk /r

    now go to your (device manager)

    now once there you will want to select from the toolbar of the window(veiw) then a drop down menu / from it you will select (show all hidden devices)

    now if you see any (red or yellow) quotation marks , make a note of what they are

    now go to the (event veiwer) this is thoughu the (administrator tools) in the control panel here you will find 3 to 4 subcatagories

    you will want to check each of them for this is where windows keeps track of all errors
    now you will want to make notes of the errors that have been recorded ( you do not have to make notes of double entries just of the dates of their happenings & how many there is)you will get more information on the errors if you (right) click them / then select properties
