By default, Vim will only pop up a completion menu if you explicitly tell it to, by pressing one of the completion key combinations: <C-N>, <C-P>, <C-X><C-O>, etc. If your menu pops up automatically as you type, it must be a plugin doing that.

You can check to see what mapping is actually active for the <Tab> key, and what file defined that mapping:

Insert and command-line mode:
:verbose map! <Tab>

Normal, operator pending, and visual mode:
:verbose map <Tab>

If these commands show your mapping, then there must be some problem with the mapping or Vim settings interfering. If these commands show some other mapping, check the file it says created the mapping.

Note, if you have the 'paste' option set, your insert-mode mappings will not be used. I'd double-check that option value before doing anything else.
