m Reduce the size of the disk cache in the Memory control panel.

m If you use a RAM disk, reduce its size or turn it off in the Memory

control panel.

m Use the Extensions Manager control panel (in the Control Panels folder

inside the System Folder on your hard disk) to turn off extensions you don’t
need. Then restart the computer. (You can use Extensions Manager to
create different sets of extensions for special situations.)

You need to restart the computer for these changes to take effect.

If these suggestions don’t work, you can increase memory by installing a
RAM expansion card in your computer. See Appendix C for information.

The computer won’t restart.

m If the computer freezes, you can try to “force” the program you’re using

to quit by simultaneously pressing the keys Command (x), Option, and
Esc on your keyboard. Then click Force Quit in the dialog box that
appears. (Note: Unsaved changes in your current documents will be
lost.) Immediately save all open documents, quit all other open programs,
and restart the computer.

m You may need to reset the computer. The method of resetting you should

always try first is to press the Command (x), Control, and Power keys
simultaneously. If the computer does not start up, connect the power
adapter (if it is not already connected) and press the reset button (marked
with the icon I) on the back panel.

Note: You will lose any work you have not saved.

m If the problem recurs, reset the parameter RAM (see “The Computer

Makes an Unusual Sound at Startup, or You See a ‘Sad Macintosh’ Icon,” in
the section “Problems Starting Up the Computer” earlier in this chapter). If
the problem still occurs, see Chapter 6.

Every time the computer starts up, it rebuilds the desktop.

There may be a folder on your hard disk that has the same name as a file the
computer uses to keep track of information on your disks. Manually search
for a folder named “Desktop” or “Desktop file.” If you find one, rename it
“Storage.” Then restart the computer. (Do not use the Find File feature to
search for the desktop file. It may find it but you may not be able to access it.)
