How exciting! You got a new computer for Christmas. It’s sleek, shiny, and so much faster than what you had before. That’s great, but it doesn’t mean you should leave it untouched.
Your old computer is beginning to slow down. So, you invest in a shiny new laptop. The clouds part and the sun shines down on this bright and lovely new device. Everything will be faster and easier. Only, from the first day, the new laptop is lagging. Why is it running so slow? One of these might be the reason.
