Hello, my sister's laptop recently stopped working at all. Every time I start it up it will say there has been a hardware error and will give me two options: "Launch windows repair" and "start windows normally" When I launch windows normally, it shows a brief blue-screen and takes me back to the two options. When I launch windows repair, it goes to a black screen with only a cursor. Please help! I even have a windows 7 OS disk if that can help me at all.
