Problems and solutions
This section lists some problems you might experience along with suggestions for solving
them.
The monitor is dark after you turn on the computer.
■
Follow the suggestions under ÒProblems starting upÓ on page 9.
You see a question mark icon instead of the MacOS desktop when you
start up.
■
There may be a problem with a SCSI device connected to the computer. Disconnect all
the external SCSI devices, then restart your computer. If your computer starts up
normally, verify that the SCSI devices are connected and terminated properly, and that all
devices in each bus have unique SCSI IDs. See ÒUsing SCSI devicesÓ on page 47 for
more information.
■
System software is not installed on the computer. Follow the instructions in ÒReinstalling
system softwareÓ on page 64 to install the software.
A blinking question mark icon appears when you start up.
The blinking question mark indicates that the computer cannot Þnd its system software. This
may indicate a problem with the start-up disk or a problem with the system software.
■
Start up your computer from the Disk Tools ßoppy disk or Power Computing MacOS
CD-ROM. Use the Disk First Aid program to check and repair your disk. (See the Disk
First Aid entry in Macintosh Guide for instructions.)
■
If repairing the disk does not solve the problem, reinstall the system software as
described in ÒReinstalling system softwareÓ on page 64.
A ßoppy disk icon with an X in it appears.
You inserted a non-start-up ßoppy disk during the start-up process. If you wait a few
seconds, the computer will start up normally from the hard disk. Remember to insert ßoppy
disks only after the start-up process is completeÑwhen the MacOS desktop is visible.
An icon with a sad face appears when you start up.
This can indicate a problem with the system software or with the computer hardware.
■
Try starting up from a different diskÑthe Disk Tools ßoppy disk or the Power
Computing MacOS CD-ROM, for example. If you can start up with a different disk, it
means that there is a problem with your system software.
■
If the sad face icon continues to appear, contact an authorized service provider. There is
most likely a problem with the computer hardware.
