*Network Cable Unplugged-Known Good connection. Help!

Team,
OS: Windows XP 64 , Windows XP Pro
Hardware: Nforce 4 Asus A8N-Sli , AMD Athlon FX-60, 2x 8800GTS , 80gb HDD Sata, DVD-Rom , 4gb Ram.
Software: Drivers used : Original known good Mobo Driver disk, Updated Chipset Drivers (Same issue replicates on both.)Display Drivers (Legacy and Updated- Sirob). AVG 8.5 - Disabled during appropriate points.
Current Stage (After several Attempts): Completely Fresh install of XP64, installed mobo driver disk (known good). Installed AVG checked for any network applicable settings before plugging in network cable.
Other Trouble-shooting : Cleaned contacts and left to dry (alcohol). Tested network Drop on another PC. *Cried

Result = *Network Cable Uplugged, and no lights.
Driver installs without error, network card properties look normal as well as the bios.

Previous attemps:
Known good motherboard used to replace this motherboard + windows reinstall = same issue.
As above with PCI network card installed (known good) = same issue as above.

Notes: When attempting to uninstall/reinstall driver for network card the following occurs: Using only the onboard nic it installs and renames device "Network Adapter #" such as 2, and there are other nic's installed physically or software wise. If you repeat this process the # raises I got it up to like Network Adapter 9.
This started happening after I left machine sitting next to my desk for a month or so upon booting up.
I've also tried to find an settings in bios for network/lan onboard, all thats present is is disable onboard nic and disable network boot.

I've got 9+ years IT experince I'm hoping a vetran out there has ran into this and can help shed some light on this problem that I have exhausted myself on. Thank you for your time and input.
