Problems Starting Up - Power Computing PowerTower Pro User Manual

Chapter 1, Getting Started
When the computer Þnishes its start-up procedure, you should see the Mac OS desktop.
If you see a blinking question mark, you need to install the system software on your
hard disk. See Chapter 4, ÒTroubleshooting,Ó on page 29. If you see a blank screen or
anything not already described, see the next section, ÒProblems starting upÓ
When you need to shut your computer down, follow the instructions in ÒShutting down
the computerÓ on page 12.

Problems starting up

If you see a blank screen when you start up, check the following items to identify the source
of the problem:
Are the computer and monitor plugged in? If they are plugged into a power strip, is the
power strip plugged in and turned on?
Are the computer and monitor turned on? The power button on the front of the
computer should be lighted. Most monitors also have power lights, which should also
be on if the monitor is on.
Is the video cable securely connected to the monitor and computer? (If you need to
reattach the cable, Þrst turn off the computer and monitor.)
Are the keyboard and mouse properly connected to the computer? (If you need to
reconnect them, Þrst turn off the computer to avoid damage.)
Is the brightness control on the monitor turned too far down? Check the documentation
that came with your monitor for instructions.
