Apple Power Macintosh 7600/132 Series - Manual (Page 97)

If your computer’s performance decreases
If you notice a decrease in your computer’s speed and general performance
after you add special software like a control panel, system extension, or
custom utility, it may be because this software does not work well with Power
Macintosh computers.
m To find out if a system extension or control panel is the problem, use the
Extensions Manager control panel to turn off system extensions. Next, use
the Extensions Manager control panel to turn the system extensions and
control panels back on one at a time, restarting and checking your
computer’s performance each time until you identify the software that is
causing problems. Contact the software’s manufacturer for information or
an upgrade.
m To find out if a custom utility you’ve added is the problem, drag it out of
the System Folder. (This software may be in the Control Panels folder or
elsewhere inside the System Folder.) Next, restart your computer and check
its performance. If there’s an improvement, the new software was probably
the cause of the problem. Contact the software’s manufacturer for
information or an upgrade.
If you still do not notice an improvement, follow the instructions in
“Installing or Reinstalling System Software” later in this chapter to reinstall
system software on your startup hard disk.
