I have been using Macs for years and I have always been able to keep them running smoothly. My brother recently gave me an old Power Computing PowerTower Pro 200 machine. He said that it has never worked properly and just crashes for no apparent reason. I took the machine, stripped it down, re-formatted the hard rives, put new RAM inside, and did a clean install of OS8.5. I even rebuilt the DeskTop file as outlined in the Apple Technotes library.
It did no good. I get errors like:
"The Finder has unexpectedly Quit"
"App [appname] has unexpectedly Quit"
Sometimes the thing just freezes.
I have run out of ideas. The only thing I can think of is that there is some sort of hardware problem. Any help would be appreciated. I am spending a lot of points so I want a well-thought-out reply.
