You can make some simple changes to your BIOS (the initialization program of your computer that runs every time you start up) that will drastically increase the speed of your system. To enter your BIOS, press the designated key during the power-on self-test. If your computer doesn´t appear to have a power-on self-test, and instead you have a splash screen with the name of the system builder, check the computer´s manual for information on how to enter the BIOS (or, worst case, you could always call the manufacturer).
