The Error Checking utility is provided to check for and repair any disk errors. It is a tool provided by Microsoft that should be used just like the Disk Defragmenter and Cleanup utilities. These tools are designed to help you optimize the performance of your PC. The Error Checking utility will check the files that are stored on your computer for integrity as well.

Over time using your computer can cause bad sectors to develop on your hard drive. These bad spots can slow your system down. Sometimes bad sectors can even prevent data from being written to your drive. The utility that checks for these errors can repair or section off the portions of bad space allowing your system to perform flawlessly. It will also check for misplaced folders and files. This utility should be run weekly to prevent the loss of data.

The amount of RAM you have in your system is also important in how fast your computer will operate. While most systems allow you to expand and add RAM some do not. ReadyBoost is an alternative that you can use if your system is running the Windows Vista or 7 operating systems. ReadyBoost allows you to use a flash USB drive as virtual RAM for your computer. This lets you improve how your computer performs without having to add internal memory.

These are three things you can do to try to improve how fast your computer runs. If they do not work then you may consider buying a new computer.
