I have one of these computers and it worked fine  (for about two days) until it loss it power and then i couldnt even log back into it asked for a password that i wasnt even famliar with. It had a white screen and asked for a admin password. I took it to "the geek squad" they told me i had to pay around $250 for a new upgrade system or something like that. I am not a technical person with computers but i can navigate. I would knew buy a computer off the internet again, lesson learned.
