That is known as a kernel panic.

Have you tried cloning this system to another computer? Typically this is due to bad memory. A simple test, if it has two DIMMs is to swap them. It won't fix the problem but it should result in a different symptom. If it does then one (or both) are bad. I worked in a grade school and used CCC to install the OS several times on about 250 computers. I perhaps had a problem a handful of times, all related to the specific computer and not to the cloning process. I may have even had a kernel panic (KP) but I can't recall it happening. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
