When I turn my Toshiba A45-S151 laptop on, I first get the screen that shows the Toshiba logo and has the four icons under the logo. Usually the next screen is black, has a cursor in the top left corner, then a bunch of text pops up on the screen followed by the screen with Windows loading up. My problem is that for some reason, when I get to the second screen (the blank one with the cursor in the top left) NOTHING happens. It just remains blank with the cursor blinking. The fan turns on, but nothing else except for the blank screen. Unfortunately, my cd/dvd drive isn't working anymore either, but this happened months before I started having this problem, so I'm not sure if the two problems are interconnected.
