  1. You would like to change or already changed ?

    And PC usage 40-60 : what do you mean by that ?

    What is the exact make/model of PSU ? Just telling 500W wont help. Though GT430 requires little power to run.

    And yes you can down load drivers from internet.

    I already changed ( forgot to mention )

    i didn't open anything and when i check my CPU Usage ,its became 40~60% somehow.
  3. It could be the process it taking place in background, so the CPU usage is that high. Check the Task Manager to see which application is using the CPU that much.

    And did you properly connected the GPU and installed the driver for it.

    Already check and already end some processes but still the same
    Well, i download the latest driver at www.geforce.com though and not from Installation cd coz my cd-rom broke :<

    I told you to look for which process is taking up so much of CPU usage, so that you can get a idea what is going on.

    Can you tell me exactly which application is taking up so much of CPU juice ?

    Else backup everything and format the OS, then clean install it with a bootable media(DVD/USB). I think the problem has something to do with the driver level/OS malfunction issue.
