The Windows 2000 SYSTEMced error occurs when the system can’t load the SYSTEM hive of the registry. The reasons include the SYSTEM hive being damaged, missing or too large to load.

The cause I’ve experienced most often has been the hive being too large to load. The SYSTEM hive has to share 16 MB of memory with several other processes when it is first read so if the hive is 16 MB and the other processes take up 3 MB it just can’t be read. Microsoft has instructions for recovering from a hive that gets too large in knowledge base article Q269075. However, I’ve never been able to recover a system using only the method they specify. Microsoft assumes that the SYSTEM hive is too large because there are a large number of shared resources and their fix is to eliminate the key of the hive with the shares in it.
