problem in display incompletely wp site on local host

I used to work with my wp site without problems before but I have a problem now and that is that my site is displayed without style(just html) on local host. -I think the problem occurred after installing IIS or Microsoft SQL Server or VisualStudio. -I also stopped the IIS through the "IIS Manager" but the problem was not resolved. -I use xampp. Please help me get my site fully running again on local host.
