The network card in one of your computers is failing and sending out junk data on the network.

Does it tell you which port is causing the error?  If so, you could figure out which computer is attached to that port and replace the card in that computer.

Is that what it is? The computer connected to that port is a web server... it has two cards I will switch to see if it stops...

If that computer is a Web server, it could be the network card or it could be a Denial of Service attack.  I would start by trying the network card.

You can run wireshark on any port in the same VLAN to see what is the source MAC address of the excessive broadcasts and then track down that device using the forwarding database of the switch.
