Vista very slow even with 4GB RAM RRS feed

  • Question

  • Vista slows down so bad the mouse cursor cannot catch up..
    Moving windows around becomes very slow too..

    I have an Acer 5520 laptop with 4GB RAM. AMD Turion64x2
    Bought it 1.5 months ago.. with Vista Home Premium preinstalled. 

    Added 2GB after noticing the slow down. which did not help:-((.

    With Dual Core processors and so much ram IT SHOULD FLY BUT  doesn't even show decent speed.

    I noticed the following..

    1) - System starts OK  TaskManager/Performance shows
    Total Memory = 3070 (Why not 4GB?)
    Cached ~
    Free ~ 1700

    2) Gradually Cached RAM goes upand Free memory goes down  (as expected?)

    BUT Slow down starts when free memory approaches zero

    e.g. Cached = 2042  and Free is below 30

    I see about 89 processes at the beginning.
    Processes go up to 93  as I start programs and CPU usage may go up to 25% 
    Physical memory is always below 50%...

    3) If I close some programs Free memory may go up to 50+ and response gets better..(Still slow but not that much)


    A) What may be the root cause? Is there  way to fix this?
    B) Is there a dependency on Free Memory vs. Cached memory?

    The issue is likely to be caused by third-party programs or viruses.


    I suggest trying the following steps to troubleshoot the issue:


    Clean Boot


    1. Click Start, type "MSCONFIG" (without the quotations) in the Search Bar and Press "Enter" to start the System Configuration Utility.


    Note: Please click Continue if the "User Account Control" window pops up.


    2. Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray).

    3. Click the "Startup" tab, click "Disable All" and click "OK".

    4. Restart the computer and test the issue.


    Note: Clean Boot is a troubleshooting step. If some programs have been disabled, we can re-enable them later. If you see the System Configuration Utility, check the box of "Don't show this message" and then click "OK".


    Please test this issue in the Clean Boot environment. If the issue disappears, we can use a 50/50 approach to quickly narrow down which entry is causing the issue.


    If the issue persists, please update your anti-virus program and scan for viruses.


    For the reason why only 3GB memory is recognized by your system, you can refer to the following article:


    The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed



    In addition, we usually set the virtual memory 1.5 times as big as the physical memory.


    Hope it helps.
