Maybe resetting the entire TCP/IP stack would help.
Lets try flushing DNS cache and renewing your IP.
Flush the DNS cache and restore MS's Hosts file ...
Copy and paste these lines in Note pad. @Echo on pushd\windows\system32\drivers\etc attrib -h -s -r hosts echo 127.0.0.1 localhost>HOSTS attrib +r +h +s hosts popd ipconfig /release ipconfig /renew ipconfig /flushdns netsh winsock reset all netsh int ip reset all shutdown -r -t 1 del %0
Save as flush.bat
to your desktop. Right click on the flush.bat file to run it as Administrator. Your computer will reboot itself.
If that doesn't work I would try clearing the cmos on the board before I reformatted. Sometimes power surges or other problems can wreck the NIC and it won't function any longer until the cmos is cleared. Reinstalling the driver
for this adaptor might also be worth doing.
I may be able to spot other problems if you can post a screen shot of your ipconfig/all.
