Hi, my pc shut down a couple of times on its own. Then two days ago my wife installed her new phone software on it and was coverting mp3s etc to mobile friendly format then it shut down. Since then it won't start Windows. I can't even start it in Safe mode although I can get into the Bios. In fact it doesn't seem to shut down in Bios, only when I try to start Windows.

Those picture are hogging memory and could be slowing down your phone.
