Thanks trying the software now. Do you know any cpu clock control software so that I can control how fast or slow it goes?
The simple thing to do is to go to Control Panel>Power Options and select Power Saver mode. That will reduce your cpu speed to the minimum. For more control, you can use Throttlestop. It's for overclocking, but I believe it can also be used if you want to underclock. Be warned, it gives you a lot of control and is not very intuitive.
