The Windows operating system is not foolproof.  Sometimes it gets cluttered with excess files and folders and it can start to get slow.  Instead of buying a new computer, try cleaning up your present one.  I suggest looking into a few software programs to help you optimize your PC, such as a registry cleaner.  The best registry cleaner we’ve reviewed is RegCure, made by ParetoLogic software.  RegCure is easy to use and when we used it to clean up our registry and disable certain startup programs we had a good improvement in the speed of our computer.  It’s also compatible with up to 64 bit Windows 7.
