But as time progresses, maybe months or years, the PC speed decreases gradually. It goes so slow to an extent that we have other thoughts of buying a new system and replace the current system.
So what exactly happens that the speed goes so sour. Computers are made to last very long and help us for our online purposes and tasks. In fact even office systems last longer than home systems. Also offices use older systems that run as fast and neat as compared to newer systems.
At home, we install new software, games, tools and a host of other applications. Over time when we don't need these applications, we uninstall these applications and reduce our memory consumption.
But the most important part is that even the registry goes on entering data for the new applications. When we uninstall our applications, the entries in registry still exist. So our systems always execute instructions for software that are not in our systems and it ends up doping more work than required.
You can remove unwanted registry data by referring the video below,
Also spamware and malware slows down our systems and cause unrequired slow speeds. Viruses and Worms are also mostly responsible for the ever reducing system speeds and drive crashes.
You can scan your system with the newer versions of anti-virus and keep your system safe. Softwares like Avast and Kaspersky are portable and very handy.
My article on Tips and Tricks on better system performance also explains things you can do to keep your system sound and working at its full potential.
