it just started working again. Can't explain it, but i can't afford any repairs now anyway, so i'm just going to cross my fingers.
I should add that when i replaced the PRAM battery last year, i noticed that the clip that holds the battery in was not that tight on the battery. It was a little loose, so I might look at that should the computer start acting up again.
Thanks for your help everyone!
well, it happened yet again. I'm sure its time to replace the PRAM battery now. It's about 2 years old. The weird thing is that this happened last year and it just fixed itself, and has been fine for a year. It still doesn't seem like its the PRAM battery, but that's what I'm going for.
By the way, the problem is that every time i clean out the fans and put the air deflector and cover back on, the computer doesn't boot up, the keyboard is unresponsive (can't reset PRAM, and can't boot up from install disk holding the C button), and the display won't turn on. All that happens when i push the power button is that the fans start spinning slowly, as if the computer is idle (it never makes the apple sound, nor does it go through a boot up process), but after 30 seconds the fans go full speed. Still no display.
Anyway, i'm ordering the PRAM battery...
Dear guitar guy,
FYI, japamac has left the forums. This is not the place to discuss reasons, of which I have only partial knowledge, but he seems gone for good. Last post was in August 2012.
He still has his web site. You might see if you can find some useful info there:
We all are missing his wisdom.
