Okay, Windows XP has an excellent troubleshooting tool- the Event Viewer. These are logs of everything that happens on the computer for System, Apps and Security Audit. Follow this please:
Control Panel> Administrative Tools> Event Viewer: Click on System and Apps, one at a time and do this:
Right click on Error that corresponds to the failed load> Properties> Click n the Copy icon below the down arrow on the top right> Paste Error to Wordpad or here Ctrl V.
Ignore Warnings and Information Events. If you have multiple, recurrings Errors with the same ID#, the same Source and the same Description, I only need one copy.
Going by what you describe, it sounds like a connection and/or server problem. Your browser may not be set up correctly according to your ISP, or the home page you have might be having a server problem.
