Thanks, pc & nasty. I do not think this is pirated copy. Wallpaper stays in place. It was given to the Hispanic husband of a friend of my wife's, for helping move furniture (that's his job). He would not know to ask about such things, nor know what to look for. from what I can tell they are fairly tech illiterate.
I will try nasty's suggestions as well. I did not know about Smitfraudfix, but have already run the others, but not in safemode. will do and see what happens. But this thing is sssoooo ssllooowww. takes a night to run 1 scan.
It has 1gb mem (win7x64, 5400prm HD). I was going to bump it to 2gb. any reason to go 4gb for web surfing, youtube, netflix, office, kids games?
