  1. You can check what takes up the CPU time in Task Manager, from the Processes tab.
  2. It could be that your PC is Dell and that the PSU is inefficient. Make sure that it is at least 600 watts.

    Really ? !
  4. If you have a sata hdd and the bios is set to ide mode rather than AHCI then this will reduce performance quite a bit. Unfortunately, you cannot change to AHCI mode after installation, you would need to do a clean install if you change the setting.

    Sometimes, though, the setting is a dual mode for both IDE/AHCI then it might be set to IDE, try to change to dual mode. If it doesn't work, you get a BSOD then just change back to IDE mode.

    You don't get good performance if the PSU is 264 watts.

    Wattage does not tell the whole story these days.

    There are 350W PSUs that are superior to some 500W variants. Manufacturer, weight, Amp distribution, noise & heat levels, ATX specification, form factor, modular connectors etc .... are all things that need not be overlooked when comtemplating a PSU purchase. Hardware, especially graphics cards must be considered.

    Here is a good way to determine what one needs, based on the system being run.

  7. Try defragmentating your HDD, run CCleaner, check in the Task Manager in the Processestab if there aren't any weird programs running.
    Try hitting the CPU Usage a few times so it sorts out the highest usages on the top
  8. @Ksiemb - thanks for the update about PSU's but your link returned -

    "Forbidden

    Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

    Perhaps the Asker could give an update about his rig? It could be mixed ram or has got an older PC running Windows 7?

    @TenPc: Must be your security software - I have no problem with the link.
