Have you wanted to upgrade to Microsoft Windows 7 or just do a fresh install and don't know where to start? Running Windows 7 can be a huge time saver, and, in many cases, will run much faster on the computer you already own, with not much required. Maybe a memory upgrade to give your computer a little more speed. The computer may not be the fastest one on the block, for more speed you need at least two GB of RAM for basic computing.
