Boot takes 20 minutes, no bluetooth
I'm looking for some pointers on how to diagnose the issues I am seeing on my 24" iMac (early 2009, 2.66 A1225). Here is a synopsis of what I am experiencing:
1) Boot up takes about 20 minutes, or more... generally the machine sits at the "white screen" for most of this time.
2) When machine comes up, the blue tooth interface simply does not exist.
I've taken a few basic steps like resetting PRAM ... I did boot from the CD to run the AHT but that yielded nothing, in fact, it hung. I let it run over night... about 18 hours straight.
So, I am trying looking for some advice on some things I could look at that could give me a clue what's going on - honestly, at this point the machine is not worth taking to a shop. *IF* I can get it to work it will either be my 7 year old daughter's first computer, or dedicated to hosting my film scanner which requires a fire-wire interface (and for which I have a Mac mini that could do the same thing).
For all practical purposes, this could easily just be sent to recycling but I'd like to use it as a practical learning experience.
Right now, I have two working theories:
1) It's a problem on the logic board (from what I can tell, expensive part if you can find it)
2) it's a problem with the blue tooth module (I am assuming that is a daughter-board)
I am also curious, in terms of circuit cards, what functions of this model iMac are built on to the logic board and which are provided by daughter-boards?
