Windows 7...I cannot download any programs

If you're using a brand new computer direct from manufacturer, your activation should be taken care of. Are you sure you're not actually downloading? Check your internet options to see where downloads should be saving. Now check that directory after clicking this link: Download SpeedFan 4.40

If you have a secondary computer, download an installation of Firefox and install it. After it's installed, come back to to this page and attempt to download from here. Once you click the link hit Ctrl+J if a dialog doesn't come up. That will tell you whether or not you're downloading the file.

Sounds like your internet is down for some reason.

Make sure you're activated for posterity's sake.

Start > Right Click Computer > Properties > You should see a line that says Microsoft Windows is activated and a software key.

I.E.

But you can't download anything through IE or FF? Did you check the activation?

What security software are you running? Preinstalled OEM crap antivirus? Stuff like that?

Good Point, Turn off your anti-virus and/or firewall and try to download.

BTW, What happens when you can't download? Do you get an error or a not 404 page like before? Do you just not see anything?

Did you run and malware and antivirus scan as suggested?
