i turn on my laptop (a levono N500) and it wont load to the main screen, so it gives my two options, "start windows normally" (which doesn't work, it just brings me back to these two options) or to start it using a program to fix problem, and in parenthesis it says recommended so i clicked it. now after it says microsoft window it trys to load then goes to a screen that says ThinkVantage Technologies. it's like wide screen and has a picture of a life preserver on it and it says levono in the top right corner. but nothing else happens. there's nothing to click on and i left it like that for an hour or two and it's the same screen. what do i do?
