RAM guru question?

[mike enriquez]

Is there a RAM Guru in the group that can shed some light on my RAM 
question?
I understand that programs upload into ram when a computer starts, but 
how can we make sure that the ram gets emptied when a computer is shut 
off. When a computer is shut off are there any program still living and 
enjoying themselves in the RAM chip?
I would assume there is software to make sure your ram is clean but I 
don't know anything thing about this.
Can anyone in the group explain this to me.

Thanks
