First time I got a blackscreen on my laptop was the Toshiba Satellite C50B 14D model. I tried many things and managed to fix it temporarily but it went back to black screen again.
Second laptop was the Toshiba Satellite C50D A133 and that one receieved a black screen again. I didn't understand why they kept getting black screen. But I found out that for both laptops, it always happened after a driver update. I used iOrbit driver booster to update my drivers and when I restarted after it had finished updating all the drivers the black screen occurred and both happened on windows 7 as well. It's seriously a problem.
