Troubleshooting Windows NT boot
problems
This chapter deals with problems that occur between setting the switch to “on” and
the appearance of the desktop on the monitor screen. During this period, the power-on
self-test runs and Windows NT boots.
Pre-boot problems
The pre-boot sequence of events occurs when you first turn on the computer before
Windows NT loads and begins to run. The problems that occur during pre-boot are
primarily hardware problems. These problems are typically in the Applications
Processor board or in one of the peripherals attached to it: the display, the keyboard,
the mouse, the system drive, or the diskette drive. When these events are complete,
the computer is ready to begin loading Windows NT.
The following table lists some possible problem symptoms that you might see as error
messages that appear during the Power-On Self-Test (POST).
