Not booting up even in safe mode

Hi, My Mac seems to have developed several personalities. Sometimes boots ok, some of time half boots then white screen, sometimes when turning on get a blue and white vertical striped screen, sometimes half boots then shuts down and restarts. Various issues. Anyone got any ideas?

Answer this question I have this problem too

Is this a good question?

@arbaman - Some of the systems in this series uses a combo PCH/NVIDIA GeForce GPU chip setup which had a fair amount of problems.

@terrych “blue and white vertical striped screen” Most likely faulty graphics

“some of time half boots then white screen”and “sometimes half boots then shuts down and restarts“ MAYBE the drive is failing
