Richard is right. You can find useful scripts to minimize, warm up and
equilibrate your system at:

I have to warn you that you should modify some parts of the scripts in
order to obtain accurate results (for example, disable the flexible
cell)

Prior to the production run of any simulation you need to do a run with
the position of the protein restrained, with pressure coupling on, to
equilibriate the rest of system. Otherwise this will happen and your
results will be rubbish.
