Apple 8500/150 Series, 8500 Series appendix If your computer’s performance decreases

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.

mTo 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.

mTo 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.
