Which motherboard is it? A1278?Thanks, you guys. Turned out to be a dead lower ram slot, apparently a known problem on this model. And of course, it didn't happen to me until 4+ years after Apple stopped fixing it for free. So I can replace the logic board, or be happy with 1GB of ram (instead of the 1.5 that I had) until it dies and save the money for an upgrade (my next mac refurb). This thing's 8 years old, so it's time to let it go anyway.
Maybe we could take a look on the schematics and fix it. Got any soldering irons?
if they ever make a mod...the shape off a cat....i could be tempted
