Use your computer for some time and you'll soon find your system tends to slow. This isn't due to the installed software requiring additional system requirements, such as more memory or a better graphics card. It's simply due to the way Windows will write data to your hard drive. After a few months, it will stop trying to store information logically and data will be located all over the drive. This means it takes far longer to start your computer, load important software, write files to your drive and more.17 Mar 2009
