Computer Issues

I have used about 65 GB of my Hard Drive, but an extra 80 GB is used up and unaccounted for. Does anyone have any idea what could be causing this? I'm kind of nervous because if I keep losing hard drive space my computer will be inoperable.

In the great tradition of Physics, I am naming this phenomenon "Dark Gigabytes".
