Disk Space Disappearing by the Minute

[annie_time]

Hi all,

The disk space on my Windows Vista machine has been disappearing very mysteriously. I tried what lots of pages on the Internet suggested, which is to remote restore points and shadow copies, but apparently I don't have any of these. I tried a virus scan and a SpyBot scan, and I also downloaded CCleaner, but none of the above helped me figure out what the problem was, and none solved it. The disk space is disappearing ridiculously fast, on the order of say 100MB disappearing in an hour. Does anyone have any idea what might be causing this?

Thanks!
