What makes the speed up of your computer the memory or the hard drive?

The main thing that will determine if your computer is slow or fast is the hardware that it has. The faster the hardware the faster your overall computer speed will be (generally). The main that slows down your computer is the the operating system. If you have used Windows XP in the past and made the move over to Windows Vista you would have noticed a dramatic decrease in computer performance. The reason for this is because Vista is actually slower than XP. The main reason for this is because Vista has a lot of fancy things on in that are designed to make it look pretty which are of no use to you when it comes time to actually use the computer.

So the two main things that you have to consider are your computers hardware specifications and the operating system that you are running.
