Been doing some research, and I'm pretty sure I have a kernal panic. It all started with a crash then it was taking my Ibook forever to start up so I started up from the os x install cd (which also took longer than usual). From there I ran the disk utility and tried to disk verify and repair the disk when it told me I had an invalid node structure. No success, so I figured I don't really have anything on it I cared about losing so I erased the disk and did a fresh install of 10.3. Everything was going fine until I got to the internet options portion of the set up wizard. A black screen covered the existing screen and I had a box with a apple power symbole in it that told me in 4 languages that I need to restart my computer. I've been looking around the net and found that I might have a kernal panic, which could either be caused from a failing HD or bad ram. I replaced the ram with a stick that I knew was good and still got the error. Is there anyway to check the onboard ram on the logic board before I order a new harddrive. Also I don't think it can be any of the other causes of a kernal panic cuz with a fresh install I don't really have any third party extensions, and I'm sure I can put 10.3 on it because i have 18gb HD, 700mhz, around 364mb ram. I'm thankful for any help or direction on how to test the onboard Ram. P.S. I ran the Apple Hardware Test before I did a fresh install and everything passed, but I read that it can sometimes give you a false positive.
