If your PC has been in use for some years now, you will probably be seeing some critical issues and problems in it. Well, this happens with all computers and it could happen for several reasons. For instance, over time, PC components break down, the software turns obsolete and dust accumulates in cooling fans. All this prevents your system from operating the way it is meant to. And just like humans, your PC begins to age. In fact, your PC needs not to be old, to slow down. Furthermore, with regular usage, your PC is constantly accessing the Windows Registry. The registry keeps track of all programs installed on the system and contains thousands of configuration data files which prompt your PC to run the way it does. When it is cluttered with junk files, the PC slows down, crashes and is exposed to viruses. Temporary Internet files can also cause your PC to slow down.
