Q: Macbook Pro grey / blue screen
MBP (2009, Snow Leopard 10.6.something - need to update my profile product) all of a sudden won't start. I shut it down properly, went out for half an hour, came back, booted up, and it stuck on the login screen with a spinning wheel for about 10 minutes. There was a crackling sound coming from inside the laptop (as if the processor is running in overtime - lasted a good minute), around the area just below the arrow keys (or if you're looking at it from a side profile, from just to the left of the CD drive). I force shut it (holding down the power button), and tried to restart. The chime started, but this time the screen just went blue / grey (was hard to tell, not obviously one colour or the other!). Crackling sound still there, but in shorter duration (10-20secs).
Following some troubleshooting tips, I've done the following:
1) boot in safe mode (using both methods: start & shift; and start & shift-cmd-v). No progress.
2) reset nvram/pram (start & cmd-opt-p-r). Screen now obviously grey, compared to the previous blue/grey colour. Did this twice. Otherwise no progress.
3) boot from install disc (start & c). No progress.
Now the install disc wont eject. Have tried to use the hardware test (start & d) but it does nothing and I can't put the Applications Install DVD in because the install disc is stuck in the drive.
The remaining steps according to the troubleshooting guide for grey screen problem don't seem applicable (it's not a peripheral problem and all my RAM is apple).
Gut feeling is that it's hardware related, largely due to the crackling sound, but not sure. Any suggestions to other steps I can take to diagnose the fault, before taking it in to a pro?
Cheers
