Caution
If you turn off the computer, always wait at least 20 seconds
before turning it back on to prevent damage to its circuitry.
If your computer is set to boot from drive C, make sure that the
IDE hard drive is formatted, and that the primary IDE
controller is enabled by checking the setting of jumper JP25 on
the system board; see “Changing the Jumper Settings” in
Chapter 4.

Make sure the power cord is securely connected to both the
AC inlet on the back panel and an electrical outlet.
The power cord is securely connected but the computer
still does not start.
Check the electrical outlet for power. Plug a lamp into the
outlet and turn it on to see if it works.
You installed or removed system components, and now
your computer does not start.
Check to make sure you have reconnected all the internal and
external cables correctly.

are securely installed in the correct sockets.
