Q: After startup screen flashing and turning blank

When I turn on my MacBook Pro 15 " mid 2010, I can see the apple logo and status bar for few seconds and theN the screen starts flashing and goes blank which is grey in colour. This thing has suddenly started and I think the reason for happening this is the recent update I have installed of Yosemite. Please help as I am trying to start my Mac since past whole week, I am unable to get solution for it. I have tried resetting the PRAM and also googled it everywhere.
