At times we would be faced with situation that the page does not load, due to some webpart issue. In SharePoint 2010, there might be a link in the error message to open the webpart maintenance page directly. In certain cases, it is not provided. So to open webpart maintenance page directly from url just append ?contents=1 at the end of the URL of respective page and SharePoint will open the Web Part Maintenance Page for it. For e.g, if the url is http://sharepointserver/sites/pages.aspx, make the url http://sharepointserver/sites/pages.aspx?contents=1 to open the webpart maintenance page. Note - the user need to have edit access on the page to open the webpart maintenance page.
