Windows 2000 may stop responding (hang) for up to one hour during the startup process. This behavior may occur if you are using some USB keyboards that have an incorporated PS/2 mouse port, and a mouse is connected to the port on the keyboard.
The delay occurs because of a longer response time for the chain of devices.
