运行MVC3应用程序时出现浏览器错误

当我试图编辑或删除时，我的浏览器上出现了一个错误，上面写着：

Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.
Requested URL: /console/Delete/PS3

但奇怪的是，当我把鼠标光标放进浏览器地址栏并按下回车键时，删除和编辑页面就会出现

你能帮我做这个吗。如果你需要任何关于这方面的信息，请告诉我，我会提供。
