Many of my friends complain that their computer worked faster when it was new, but with time the computer has become slow. There are few reasons behind this, first is that when you compare your old computer to some new computers, you may find old one slow because of old technology hardware. The second and main reason behind the computers getting slow is because of lots of applications added to Startup or AutoStart list.
The solutions to this problem is to prevent the un-necessary applications from starting automatically each time the computer is started.
Start up applications keep consuming precious memory and CPU even when these applications are not in use. So its better you know what applications are running and remove them from startup.
