小弟幫你查了一下....

停止錯誤編號： 0x00000051 (parameter, parameter, parameter, parameter) REGISTRY_ERROR

解釋：
This is a Windows 2000 Executive character-mode STOP message. It indicates a Registry or configuration manager problem. An I/O error might have occurred while the Registry was trying to read one of its files. This could be caused by hardware or file system problems. This message might also appear because of a failure in a refresh operation, which occurs when resource limits are encountered.

參考看看吧....
