I'm guessing most of the helpfull people here would like to know the extent of the problem, which operating system you're on, when you noticed the problem, some hardware info - amount of RAM, etc.
I know it's silly to try and solve a problem before I know what the problem is, but, you said optimize, so I say go to start ->programs-> accessories-> system tools, and run just about every utility you find there - check disk, disk defragmentor, disk maintenance, disk cleanup.
OK, I'm done making recommendations before a diagnosis. For now...
