Slow start up after sleep

Question

hey all,
when I wake my computer up from sleep it makes a gearing up noise as if the hard drive is getting ready, and the screen stays black for 7 seconds, then blue for about 3 seconds, and then finally the desktop appears. All of the other iMacs that I've used start up immediately, and this slow wake from sleep is affecting the performance of some of my important applications. Does anyone know how to speed the wake from sleep issue?

Answer 1

1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
