Downloading is incomplete

Hi there all, I'm the super newbie.

I'm running win 2000sp4 with IE6 sp1. When I try to download anything from various websites, the download starts, but only goes to about 3-5% then it shows that it is finished. When you try opening the downloaded file it is corrupt or cannot be opened. The file size is also smaller than shown on the site you are downloading from.

Any help will be appreciated! :sayno: :sad:
