then either something is reserving the space (such as system restore, which can reserve 15 to 30% of your hard drive space) or your explorer window is not showing the correct amount of free space.
In your explorer view, where you see the amount of free space, have you pressed F5 on your keyboard? This refreshes the view, and should also refresh the amount used...if it still remains the same after that, then I guess windows restore is reserving space. In which case you will need to plow though some tutorials to limit the amount it can use.
If I recall correctly, you will need to open a Dos box as an administrator, and type vssadmin shadowrestore resize /on=c: /for=c: and then one more value shoud be added...I think something like /size= or something..... We have a great tutorial section, you will find the answer in there. If I have the time I will look it up for you.

Also, have you run a defragmentation lately?
And, have you run checkdisk yet?
Also abudabu12, you don't have to make a new post every time. If no one else has replied to your post yet, you can simply click edit at the bottom of your previous post, and edit and add to that post. Otherwise we will have a whole stream of posts by one person, and that kind of clutters the threads.
