A few things to check:

Do you have any errors in the Event Log?

Did you try shutting down the WWW Publishing service in the Services applet in control panel, instead of rebooting? Or ending the aspnet worker process through the Task Manager?

If you have Windows Server 2003 and IIS 6 are you using Application Pools to separate the processes within your Web Server? Did you try recylcing these?

I find it strange that a reboot does not fix the problem. Are there any processes which start up at boot time, or is it possible that users are hitting your site as soon as it comes up? It may be a single process that hangs your entire system. This is possible if you are not using Application pools, and/or if you are not isolating your individual web apps. Did you recently install any new application or software?
