thank you folks for the guidance as it has been a minute since i have looked into these things. Current model is a Dell insperion XXXx...vintage 2006! Has worked 100% flawless till...the other day it would NOT boot up...drive sounded like a struggling 4 banger trying to go up a hill.....it had to "repair" itself and restart 2 times before OS was operable. (hasent been shut down since....is in hibernation mood till i get a back-up) about to just that. I do need to run excell, word, and probably do some autocad as well.
