I have looked at the other questions, but none of them have done me any good. I have been having an issue lately. When i start up my macbook pro (2009 or 2010 i think), it will start up nice, then it'll have a spinning thing under the apple like usual, and then the screen will literally flash. It will go white/black/white/black/white/black 3 times just as i described. It will then go to 100% brightness, and lessen itself back to what I have it set as. I've tried SMC reset, but not sure if it actually worked or not. I've read somewhere this could be some kind of video card issue, which i'm hoping it's not. Could someone please explain what is happening, and what I could do to fix this?
Any help is appreciated!
