Apple Power Macintosh 8100 Series - Manual (Page 83)

If your computer’s performance decreases
If you notice a decrease in your computer’s speed and general performance
after you add special software (a control panel, system extension, or custom
utility), it may be because your special software does not work well with
Power Macintosh computers.
m To find out if your special software is the problem, hold down the Shift key
while you restart the computer. This temporarily turns off certain kinds of
software. If the computer performs better without this software, the
software is likely to be the problem.
m Use the Extensions Manager control panel to turn off a system extension or
set of extensions. For detailed instructions, see the “Setting Options” topic
of Macintosh Guide, available in the Guide (
h) menu. If the computer
performs better when an extension is turned off, contact the extension’s
manufacturer for information or an upgrade.
m Drag special software items out of the System Folder or remove them
permanently. (The special software may be in the Control Panels or
Extensions folder inside the System Folder.) If the computer performs
better when the software is removed, contact the software’s manufacturer
for information or an upgrade.
Hint: If you have more than one special software item, drag all the special
items out of the Control Panels and Extensions folders. Then return them
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.
