There are numerous software applications in the market that will help you speed up your computer. However, you may be forced to make hardware changes to your computer if none of the options work. If installation of software applications does not improve the speed of your computer to your satisfaction, then you should opt for hardware changes.
You should first consider your hard disk capacity and the size of your RAM installed in your computer. The device uses these two parts for all its functions. If these two parts are not adequate for your requirements and usage, then you will definitely face problems. If your hard disk remains filled at all times because of excess storage of data, you have no option but to go in for a bigger hard disk. Do not go by size alone. You will also have to consider rotations per minute of the hard disk. If you opt for a hard disk with lower rotation per minute, it will seem slow despite the fact that there is a lot of empty space.
If the speed of your computer does not increase even after enhancing capacity of your disk and your RAM, then the best option is to enhance the configuration of your processor. The processor is the brain of your computer and a faster brain will definitely help make your computer function faster. You will have to consider hardware compatibility when making any change to these components. You cannot install the latest processor or RAM to any and every computer.
