LAN Disconnects/Reconnects contantly

It does this every 2 seconds or so continuously. I just built a computer and I have XP Pro 64bit SP2. I just downloaded teh LAN driver from here: http://www.biostar.com.tw/app/en-us/t-power/driver.php?S_ID=365

Are there any OS drivers i'm missing possibly?

It can be an issue with either the NIC card or Network Cable.

If you have an integrated Ethernet Card you need to disable it in the BIOS and Add a new NIC card in the PCI slot. dont forget to update the driver for the new ethernet card.

Also, check the network cable
