I have tried to open old word docs in vista but they will not open. Any
advice?
Although I don't know for sure that I'm right, I'll guess that you
don't have Word installed.
If you expected to find Word on your new Vista machine, let me point
out that neither Windows Vista nor any other version of Windows has
ever come with Word nor with any other significant application
software.
If you want Word, you need to buy it, either alone, as part of
Microsoft Office, or, most inexpensively, as part of Microsoft Works
Suite. Or acquire an alternative word processor such as WordPerfect or
OpenOffice.
If your previous computer, running an older version of Windows, came
with Word, it was because the vendor who sold it bundled it as part of
the package he sold you, not because that version of Windows came with
it. Some, but not all, vendors do the same with Windows Vista.
