How about telling us your exact model you have as there are issues on some versions of the 21.5" systems that can effect things here.

It sounds like you need to do some TLC on your drive:

  • Start off by making a good backup of your stuff.
  • Using an external bootable drive run Disk Utility from it to make sure the drive is in good shape.
  • You'll need to clean off at least of 1/4 of the drive (the more the better) of old documents and apps.
  • Next we want to get rid of the old cache & log files using an app like this: Disk Doctor
  • Last step! Run a drive defrag program like this if you have a HD (not SSD): Drive Genius

Other things that can help is add more RAM if you can with your system. If you have a traditional HD consider upgrading it to a hybrid (SSHD) like this one: Seagate FireCuda but be careful here as these drives only work in SATA III (6.0 Gb/s) systems if you have an older SATA II (3.0 Gb/s) you'll need the older series. The other option is to upgrade to a SSD drive like this one: Samsung 750 EVO SSD which will work in either a SATA II or SATA III system but the larger drives do get a bit costly so make sure its a wise investment given the age of your system.
