I get a blank, blue screen at startup
My MacBook stopped working. When I turn it on, the screen becomes a deep blue instead of a light grey. I have recently replaced the ram with 8gb from another MacBook (15"). I have tried removing the ram, and it detects the missing memory with the periodic single beep, so I don't think that is the cause. The fans still runs at startup, not excessively either, so I don't believe the cpu is overheating or the sensor is bad. I have tried all key combinations to reset the nvram, startup in verbose, startup in single user mode, safe boot.
When I plug in the charger, the light goes to green to orange so I don't think it could be the battery.
I have replaced my optical drive with a SSD, however, removing the SSD does not help. I still have the HDD in the original location.
If it's any issue, I also have a sticker on the outside. :)
Obviously I want to know what the issue could be, and any help is appreciated.
Is this a good question?
