Why does computer freeze ?

[Myron]

When I use my friends eMachine PC using Windows Vista, it works fine for awhile but then it starts to load slower and soon after it, it keeps freezing no matter what I do. I use Optimum online service. Is the problem with the PC, Windows Vista or with the internet service? It is very annoying.
