Hey,
A couple of days ago my Mac 'died'. I turned it on and left the room for a few minutes and when I came back, the cooling fans were on maximum and script had appeared, on top of my usual backdrop, saying something about a system failure. At this point, thinking something was overheating I did a force shutdown. Unfortunately I didn't get the entire message.
The next time I tried to boot it up it got stuck at the grey apple screen and the fans slowly sped up until, once again, they got to maximum and I had to force shutdown. I then did a PRAM reset which did nothing, then an NVRAM reset which worked!! Once.
Things I've tried since then:
1) PRAM and NVRAM reset
2) Cleaning out my machine
3) Replacing the Logicboard battery
4) Swapping RAM chipsets
5) Reseting PMU
6) Repairing the Disc permissions via FireWire Target disc mode
7) Apple hardware test. All systems passed (?)
8) Booting from disc, but holding C on startup doesn't work
9) Asking nicely
10) Tearing my hair out!
Nothing has worked. The HDD appears to be fine as I have used Firewire Target Disc mode to transfer some files onto my Macbook. The RAM chipsets seem to be fine as I have tried them in all sensible combinations.
I've seen a few threads on various sites about similar problems. Worryingly, the most common outcome seems to be fried processors.
Does anyone have any words of wisdom out there?
How do I check if one of both of my processors are fried? Where can I get replacements?
Thanks
Buzz
