DiskWarrior on HD

[Grunze]

Hi,

Is there a way I can use disk warrior on my imac internal HD?
It tells me that I cannot due to it being the OS HD..

or perhaps, can someone recommend an other way to breathe some new life in my computer? (24" white imac) I notice it moves a bit slowly wen opening and closing applications.. including simple ones like firefox or safari. I've alreayd maxed out the ram at 3gb.

Any ideas?
Thanks!

If you bought DiskWarrior, it came on a bootable disc. This is what you are supposed to use.
