At this point, Regnenth, I'd suggest getting an external hard drive or a larger internal hard drive. 64 gb isn't that much esp. if you are like me and have music, games, programs, and other stuff to store. Even if you just get a 320 or 250, it will be a great improvement. I'd suggest getting a newer hard drive. Formatting really won't solve your problems. If you end up reinstalling most of that stuff, you will still have 64 gb of space to use again. The answer should be get more space, not reformat your computer, although that would help and probably work in saving a little extra space. I'm afraid it just won't be enough.
