Things You'll Need:
A Startup Disk Or A CDROM With The Operating System On It
your desktop computer does nothing at all when you try to start it,
first check that the power cable is securely plugged in at the back of
the computer as well as into a working power outlet. It's amazing how
often this is the case.
If you're starting from a button on the keyboard, make sure the keyboard is connected to the computer.
the computer is plugged into a surge protector, see if the surge
protector has a reset switch that you can push. (If it doesn't have a
reset switch and the problem is with the surge protector, it will need
to be replaced.) Try plugging a lamp or other device into one of the
surge protector's outlets to make sure it's working.
you can hear the computer's fan or hard-disk drive, or if you can see
indicator lights on the main unit but the monitor stays dark, make sure
that the monitor is connected to a working power source, that it's
turned on and that it's securely connected to the computer via the
the monitor and computer have power but the computer displays a
"Non-system disk or disk error" message, check to make sure you didn't
leave a disk in the A: drive. If you did, eject it and restart the
the operating system still won't start even though the computer and
monitor have power, try restarting with a Windows CD-ROM in the CD-ROM
drive or, if you've got a Macintosh, with a Mac OS disc in the CD-ROM
drive. (You can start a Mac from the CDROM drive by holding down the C
key while starting up.)
the operating system then starts, your problem is probably with the
startup hard drive or with the operating system installed on it. If you
can't fix the drive, you'll have to replace it.
