then i tried pressing all these key combination to make it get out of the weird screen thing . i pressed esc and ctrl alt del and all these things and nothing happened then i heard weird vista sounds . I have vista by the way . and i heard the log of sound . Then with no luck i tried pressing the off button on the tower of the computer and held it down for 20 seconds but it failed .

Question: Why did the writer press many key combinations ?
Answer: Because they have vista .None of the above choices .Because they wanted to turn off the computer .Because they wanted to hear weird vista sounds .
