Hello,

               I have installed SharePoint 2013(Enterprise Edition) on my server .I have followed whatever the steps given.Their is no installation problem at the time of setup.Setup is completed very well.After that I have able to open SharePoint Central admin also,Using central admin I have created new site but problem is that,the new create site are not opening it gives error

but I am confusing because I am not understanding what is the actual problem because,when opening new site it asks for UserName & Password ,I am giving credentials but after processing it will gives error like (500 Internal server Error)also

I have checked the all IIS setting  It is working fine

-The Application Pool is also created and it is started still the new site is not opening.Please give me the solution regarding same

     Thanks,
