13" Macbook slowing down

I'm real sick so this has to be short. up until recently my macbook has been running fast. Now it takes awhile to do anything, it's logs on without the menubar. Can anyone help

This is always a good starting point.

If this doesn't provide a fix... then post back with a little more details such as the version of OS X you are running, whether you've tried logging in to a different user account and seeing of the problem persists, and what if any other troubleshooting you have tried.

Have you tried repairing permissions?

How full is your hard drive?

thanks alot mos def with the troubleshoot

Applications>Utilities>Disk Utility
Select Your HD then the Repair Permissions

Go to application>utilities>disk utility and select Macintosh HD (under the name of your HD), and click repair permissions tab.
Best to do this by booting from your install disk or using OnyxOnyX

Ok Tattooed friend of mine.... who was first? LOL

You got more words in than me ;P lol

I get more words in than most people most of the time when I'm typing, otherwise, I go with the less is more approach!
