[Bamboozled]

Now I need help. All of a sudden, my computer (a Gateway) is moving soooooo sloooooooow. I read through this post and got some great ideas, but I now have more questions than answers. This defragmenter thingy of which y'all speak..... is this something that comes standard on most PCs or is it a program/device that needs to be purchased? What about the Disk Clean-up?

I have downloaded LOTS of songs to my hard drive, so I'm thinking that may be the problem. I'm going to delete a bunch of songs to free up some space. I plan to purchase more memory very soon, but in the meantime, I'd appreciate some assistance from my computer savvy GC crew.
