Now a day, event the basic computer configuration provides enough performance to sustain the needs of common man. As computers are made up of lot of things like CPU, mother board and graphic cards hard drives etc laymen often find it difficult to figure out why computer is exhibiting any kind of technical anomaly.
They work fine and better on first use but as time passes with ageing, the device becomes slower and the dust settles on the computer devices. It is also believe that dust settling on devices affect their performance due to negligible electrical charge carried by the dust particles apart from this computer slows down because of accumulation of useless files and programs inside computer, capitalising on its resource RAM, Hard drives and C drive of the computer. So collectively boot up processes of the computer and other start up programs slow downs. Causing inconvenience to the users.
