My computer keeps saying ti has run out of disk space, and when I delete some old programs/files it will seem to have deleted some from the disk and shows how much free space I have, but when I check again, there is less disk space again and I haven't loaded any files, what gives? How can I get my disk space back?

I did that, and the site doesn't even appear in the history folder, but when I type the letter the site starts with, the site name pops up in the address bar.

Oh and I DID try to delete the internet history, but it still pops up, please help!

I was looking online at rings (for my girlfriend) and now when I go to type in an internet address the site pops up, i don't wnat her finding out what I'm going to get her, so how can i delete this?
