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 fi nd out if a system extension is the problem, hold down the Shift key
while you restart the computer. This temporarily turns off system
extensions. If the computer performs better without this software, one of
the system extensions is likely to be the problem. (If you just added a new
system extension, it is the most probable cause of the problem.) Return the
system extensions to the System Folder one at a time, restarting and
checking your computer’s performance each time until you identify the
extension that is causing problems. Contact the software’s manufacturer for
information or an upgrade.
m To find out if a new control panel or custom utility you’ve added is the
problem, drag it out of the System Folder. (This software may be in the
Control Panels 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 don’t know which control panel or custom utility is causing the
problem, you can drag all of these items out of the System Folder and
restart the computer. If the computer performs better when the software is
removed, you need to find out which item is causing the problem. Return
the control panels and custom utilities to the System folder one at a time,
restarting and checking your computer’s performance each time until you
identify the one that is causing problems.
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.
