Reasons behind a slow computer

Most of us generally wonder that when we had first purchased our computers, they had been in such perfect shape and worked at such fast speeds, but what makes their performance dwindle and deteriorate with the passage of time. As is very obvious, the most superficial and obvious reason could be that a new computer is virtually free of all possible garbage. With the passage of time the system starts posing troubles like a slow processing speed, frequent freezing of the screen and forces restart prompts. The reasons behind all this could be many. It could be attributed to an insufficient RAM. Every system has a distinct and specific minimum RAM requirement that must be fulfilled for the optimum performance of the computer. Another reason behind a slow working computer could be the exploiting of multitasking beyond limits. True that technology has made it possible to open more than one program at a time but opening too many applications at the same time is due to slow down your system. Also, a large number of start-up programs also slow down a computer system. Disabling these applications would lead to a visible increase in the speed of your computer.
