MacBook Pro 2009 Grey Screen.
I have a 15 inch 2009 macbook pro, and when powered on it produces a grey screen. If I boot it holding Command + Option + P + R the light at the front blinks 5 times before getting to an apple logo after about 3-5 minutes but gets no further. I have tried different RAM with the same result, and I cannot boot into safe mode, I just get the 5 blinks on the light and then the grey screen.
Any help would be amazing.
