Boots, runs for a few minutes, freezes
My iBook, over the last few weeks, has grown increasingly worse at booting up and staying on. Three weeks ago, we could use it for upwards of a few hours, and it would eventually freeze and become unusable. That is, you can still see whatever you were working on, cursor, time, etc, but the cpu simply didn't respond.
As of now, it takes slightly less than 2 minutes, once it has booted, to freeze up. Post freeze, it doesn't want to boot for multiple hours, if not days. The hard drive and RAM are less than two years old, and though I have not tested them for solvency, I believe they are ok. Battery is also new, and takes and keeps a charge. Symptoms occur with airport on or off, doesn't seem to matter.
Does this sound like anything to anyone? My suspicion is a logic board, but the fact that I can boot at all makes me doubt.
Help my iFixit, you're my only hope!
