1Gbps card

Howdy Geeks,

I have a few systems that are connected to a 1Gbps switch. They are all at default network settings and connected at 1Gbps except for one. I can't get it to connect at 1Gbps.

I connected another system to the line and it went to 1Gbps so I know it is not the wiring. I've compared drivers, bios versions, and settings to working systems and they are all the same, but it will not connect. When i change the setting of the speed and duplex to 100mbps half the system connects. The card is built onto the mobo. I don't know what would cause this other than a bad card(?). Any ideas? Thanks!
