You need to give more info. What Mac do you have? What System are you running - 10.5, 10.2, 10.3, etc?
How much ram do you have installed?
Get Cocktail, or any cron programs from
http://www.versiontracker.com to run the cron scripts, empty cache,etc.
Run
fsck
To run fsck, you first need to start up your Mac in single-user mode. Here's how:
1. Restart your Mac.
2. Immediately press and hold the Command and "S" keys.
You'll see a bunch of text begin scrolling on your screen. In a few more seconds, you'll see the Unix command line prompt (#).
You're now in single-user mode.
Now that you're at the # prompt, here's how to run fsck:
1. Type: "fsck -y" (that's fsck-space-minus-y).
(If you're running Panther, v 10.3, then type this "fsck -f"
2. Press Return.
The fsck utility will blast some text onto your screen. If there's damage to your disk, you'll see a message that says:
***** FILE SYSTEM WAS MODIFIED *****
If you see this message--and this is extremely important-- repeat running fsck. It is normal to have to run fsck more than once -- the first run's repairs often uncover additional problems..
When fsck finally reports that no problems were found, and the # prompt reappears:
3. Type: "reboot" to restart,
or type "exit" to start up without rebooting.
4. Press Return.
Your Mac should proceed to start up normally to the login window or the Finder.
