Is it possible you are using the reminder part of Entourage, Eg. A little window pops up telling you that your late for an appointment.
Try booting in with extensions off, might even be called “safe mode”. Now your going to call me stupid and say that MacOS X dosn’t have extensions like MacOS 9.
Holding down shift at startup, in exactly the same way you did in MacOS 9, prevents MacOS from loading kernal extesnions and such, I think it also prevents any startup items from starting. This might allow you to move the files. Otherwise there is single user mode (expert), or try things like duplicating the files first.
