I did a quick search through the forum and didn't see anything specific about this problem. It just started to occur yesterday and nothing has changed on the computer. (Nothing new installed and no external hardware plugged in.) Basically, it just pops up with the grey screen advising to restart. Sometimes it occurs after waking from sleep, sometimes it occurs after starting up, and sometimes it occurs in the middle of a task. I haven't noticed a specific pattern. I ran the AHT and everything passed. I also ran Rember and the memory seemed fine in the test. I reset the PRAM and VRAM and the SMC after speaking with Apple. Finally, I reinstalled the OSX clean on the machine and the panics are still occurring. This is the last panic report from the Macbook 1,1 2.0 with 1.25 GB RAM. I'm hoping it is the RAM and not something with the logic board, but am not sure if that can be ascertained without finding replacement RAM first.

EDIT: I just unplugged the power adapter from the wall and after about a minute or so, the computer restarted on its own. The battery was fully charged, but perhaps that information could shed some more light on the issue.
