remove the NIC if Found in DEVICE MANAGER,,
then remove the card from the PC,, reboot,, without the NIC in,,
let the machine start,, then power down normally,,
then re-insert card,, try a different slot too,, then reboot machine,,
As Stated ,, the Hardware wizard should find this automatically and install drivers to run the card,, SOHO is not an unknown vendor,, so it should find it,,
cheers
