5 Stars!! Internet on the computer is NOT working but ipod touches and those devices are working?

Coincidental. They've been phoning around saying that someone's computer isn't working and that they need to open a connection over the internet to your PC and steal stuff. So it's fine. Just a regular scam trying to fool the gullible.
As for your actual connection... I can't suggest anything more except unplugging and replugging the Ethernet cable (if it's not wireless) and if that doesn't work, turn the router off and on? It does the trick for me when I have Ethernet cable issues.
If it's not an Ethernet cable, it sounds like the wifi might not be enabled. If it is enabled, try disconnecting and reconnecting, if that doesn't work, turn the router off and on. That should do the trick.
