Answer: Technically, you could have a laptop that functions very well after 10 years, but that isn't very useful with many contemporary applications. Most programs will place high demands on your CPU, on your RAM, and on your graphics card in order to function properly.
You should expect to replace your computer once every four years. That's based on a cost analysis, plus the average time it takes to wear out the internal parts of the computer. For new computer contact R Computer Clinic
