So my wife's computer is now no longer opening anything or if it does, it takes forever. Instead after it boots up it, you try to open a file, etc. and instead of doing it, it will "whir" in a cycle over and over like it is trying to do something but nothiing ever happens. Is it beyond repair? or should I go to the expense of paying for an "expert" to look at it? She is very frustrated (understandable).
