Wont boot to a safe mode, wont boot to a saved point, wont boot at all, just comes up, says the .dll is no longer there or something like that, and then automatically shuts down.
I took mine to a computer repair place and even they could not ‘fix’ the problem. So they just reinstalled windows but every since then the computer is not running well at all.
If the dweebs can't reinstall Windows right, then they aren't bright enough to be computer techs. I would demand my money back and try another shop. I have never used I-Tunes at all, much less on a Linux system, but everything else your daughter wants is a cinch on Ubuntu Linux. That's what I am running right now. It updates online like Windows, but is simple to do and has never messed up.
Find a new 'computer repair place'. The one you used is clearly inhabited by Goobers. Not being snide, just stating facts.
