The computer industry moves forward at a rapid rate, and that machine you bought new last year was probably out of date when you unpacked it !! To most users this is not a real problem, as long as it does the job required they are happy, but eventually newer programs will slow down the speed of your machine and the time it takes to boot or load a file gets longer and longer.
At this point most people go and buy a new machine, but there is a cheaper option, certain elements of the computer will not have been significantly improved since its purchase, it therefore makes sense to only upgrade the parts that are out of date, this can get you a new specification machine for up to 50% less than buying a new one.
If your computer is past it's best, consider an upgrade, call us for more advice.
