The average lifespan of a new PC is now just 2 years, but desktop PCs can easily be upgraded over a period of time to keep them from becoming slow. Processors, graphics cards, power supplies can all be upgraded to make your computer run faster and more effecient, When a PC is new, the amount of memory installed is sufficient to keep it responding smoothly but in time more programs are installed, newer programs have greater requirements and the Operating System is updated to fix bugs and security problems, all of which use more resources and Suddenly your PC is a lot slower than it used to be, but with a few inexpensive upgrades we can have it running as fast as it did when it was new which saves you purchasing a new one.
