    I have an Acer Aspire 5315 laptop on Windows Vista. I installed a 3G
    RAM. It has a 1.73 GHz Intel CPU.

    Often the computer gets very slow and windows task manager will show
    CPU usage 100%. I counted the Memory (Private Working Set), the total
    of these running is never more than 0.5 G RAM.

    I did virus scan by avast! and do not have any virus.

    Please help and suggest.

  2. Which Image Name does Task Manager show to be using the CPU.

    Try booting into safe mode and see if you still get the same slowdowns.
    You can get safe mode by hitting the F8 key on a reboot. If it does, then
    the logical conclusion would be programs running in startup. You can
    disable all of these without affecting windows itself by running
    "msconfig" and disabling the startup there.

    Click on the "CPU" tab in "Processes" to sort by which one is using the most.

    Write back with your findings.
