My Nikon D800 shutter is not working properly. Whether it is in manual mode, shutter priority it fires at about 1/30 of a second. It can be set at a fast speed and still fires slow. Any ideas?

Do you have any Custom Menus set up? Perhaps if you were to go into these and do a reset, you might solve your issue. Does the problem occur when you are in Manual mode or any other modes?
