Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. Create a new account in which to test, and delete it, including its home folder, after testing.
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
- Be sure your Mac is shut down.
- Press the power button.
- Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
- Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.
Okay, followed everything you said. logged in to both multiple times and tried them out for a few hours at a time. I haven't seen the problem since ( i saw it 2 times) however, I am getting a lot of beach balls. from many programs. I am very puzzled, and cant get AHT to boot at all. I've never formatted the machine, but it appears I don't have it, no matter what I try. Any other trouble shooting you'd try? Activity monitor always shows I have enough RAM and cpu is next to nothing.
The AHT is on one of the two DVD's that came with the machine, unless it shipped with Lion. It sounds like you have a failing hard drive, or some other hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros (do this only if you know how to restore, and you have at least two independent backups.) Don’t erase the Lion recovery partition, if present.
I was wondering, thanks for your help. I have Lion on the machine, but can't get this mythical AHT test to boot. I don't know why I didn't get it but I guess I didn't, so that makes things more unknown for me of course. It used to be that I had disks and everything was easy. Easy tests, easy formats, easy installs. My closest Apple store is 4 hours away, so that *****.
Again, thanks for your help. I suspect the drive is going bad too.
Press and hold the D key before the gray startup screen appears. If Apple Hardware Test does not start up, see the Additional Information section at the end of this article.
Have internet, tried wireless and wired directly to router-
Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
This, led me to this-
If Apple Hardware Test does not start up, see the Additional Information section at the end of this article.
Apple Hardware Test is included on the DVDs that are shipped with some Macintosh computers. If the copy on your hard drive becomes unavailable, use the DVDs to run Apple Hardware Test.
or some Apple computers that shipped with OS X Lion, if Apple Hardware Test cannot be found on the hard drive, an Internet-based version starts up instead. An Internet-enabled connection via ethernet or Wi-Fi is required to use this feature. Some computers that shipped with Lion require a software update to use this feature. See Computers that can be upgraded to use Lion Internet Recovery for more information.
I Checked this-
Macbook Pro EFI Firmware Update 2.3

I've tried holding the D key. I've tried option D, tried command D. I've tried all kinds of combinations. nothing. weird right?
Sorry to be a pain, I really am. Thank you for your help.
I have a cable modem that is always on using DHCP. I'm hooked up direct right now via a cat 5 cable. Extemely frustrating. I can't imagine what if anything I'm doing wrong. I got this new at christmas and haven't touched the install, so I don't think it's "missing." Maybe it is, but still. Hold the D key does nothing. I feel so stupid, like I don't know what I'm doing maybe...
