Troubleshooting
2. Use the Extensions Manager to test the computer with Mac OS 7.6.x
Base extensions only.
The Extensions Manager is located in the Control Panels folder and can be
accessed via the Apple menu. You can also access the Extensions Manager
during startup by holding down the spacebar as the computer boots. You
can use the Extensions Manager to test the computer with only the Apple
system software, excluding all non-Apple extensions and control panels
which may be causing conflicts. You can do this by selecting "Mac OS 7.6.x
Base" from the Sets pull-down menu. Once you select "Mac OS 7.6.x Base"
you will notice that the check marks next to several items in the Extensions
Manager's extensions list disappear. A check mark next to an item indicates
that the item is active. The items without checks marks are non-Apple
system software and were disabled when you selected "Mac OS 7.6.x Base".
3. If after setting the computer to "Mac OS 7.6.x Base" the issue does
not occur, it is most likely related to a conflicting or corrupted
extension. Turn the disabled extensions on one-by-one, restarting
the computer each time, and verifying that the extension you just
added back is not the source of your issue.
If your issue returns after adding back an extension, disable that extension.
Remove the suspect extension and try re-installing it to see if the copy on
you hard drive is corrupted. If replacing the suspect extension with a fresh
copy fails, contact the manufacturer of the extension to report your issue.
They may have a newer version which resolves your issue.
4. TEST the issue when booted from the Power CD.
If the issue does not occur when booted from the CD your issue may be a
corrupted System Folder. If it continues to occur, the application you are
trying to use may be corrupted.
5. If the issue appears to be related to one application and does not
occur in other applications, RE-INSTALL the failing application.
The application may be corrupted. Replacing the suspect application with a
fresh copy may resolve you issue.
