I keep getting a BSOD when I start up (well actually the screen goes back and forth from black to grey) and then eventually an error message appears which says that windows is gathering information about the problem and will restart, and that there is "critical structure corruption"... However, when it restarts, the same thing happens. I have a Dell Inspiron laptop, running windows 8 release preview. What should I do????? Thanks in advance, Jody Anderson.
