Start with enabling development mode to see what error the 500 is hiding:

You might also look at the php error log of your server.

Are you sure you theme is 1.7 compatible?

Sounds like something theme specific. The best is to contact the supplier of the theme.

[chamiyapk]

could it be my hosting server problem? i check with another theme bought from store.same problem occurred.

tt_productimagehover is not a standard Prestashop module. So I don't think it is a hosting issue. You might try what happens if you give the theme what it wants and install tt_productimagehover first (just copy the files below the modules directory and you can install it in backoffice).

You might also spend some time investigating the documentation of your theme. Some themes have special installation instructions and cannot be installed the "normal" way.
