So you finally saved up enough money for a top of the line multimedia computer. It has that super fast Pentium IV processor, enough memory for a super computer and an ultra fast video card. Problem is youve noticed that it is slowing down; month by month the performance seems to be getting worse. Your DVDs start skipping; your MPEG3 files are halting in the middle of a song. Its frustrating isnt it? The fault is not yours, its how the Microsoft operating systems were designed. Over time they get clogged up and the performance takes a nose dive. What we are going to discuss here is what you can do to keep your home computer working at the best level possible. While this is important for any Microsoft based computer those machines that are expected to play audio and video files are especially susceptible to the slow downs.
