5) If the computer boots normally, reinstall an
extension from the Disabled Extensions Folder to
the Extensions Folder and restart your computer.
Do this step with each subsequent extension in
the Disabled Extensions Folder until you find the
problematic extension. Update the file with a
newer version or remove it from your system.
Problem: Computer freezes at desktop or
at random.
Possible Solutions:
This may be due to the hard disk driver being old,
corrupted, or incompatible with the new processor.
You may need to:
1) Update hard disk drivers to the current version.
2) Rebuild the Desktop file (an invisible resource file
where the computer stores important system
information). Restart your computer and hold
down the Command-Option keys until the
Desktop rebuild dialog box appears; click ‘OK’.
3) Zap the PRAM (an area of the Mac’s memory that
stores such information as preference settings).
Restart your computer and hold down the
Command-Option-P-R keys until the computer
chimes three times. Do not reset the PRAM
during a cold start, or you can reset open
firmware required to boot your machine after
the computer finishes booting. Open the Date
& Time control panel from the Control Panels
Folder (located inside the Systems Folder) and
reset the date and time. You may also want to
reset your preference settings for the Mouse and
Keyboard control panels.
