That’s odd. Maybe your network card is not properly installed in Windows 7. Try booting on Windows 7 then uninstall your network card’s driver from the Add or Remove Programs then go to the Device Manager and see if your network card has the yellow question mark in it.

This means that the device is already uninstalled. Restart your computer then boot again to Windows 7.

Check if Windows 7 will detect the device and asks you to install its driver. If Windows 7 did not detect any hardware during boot, I think you need to remove the network card from its slot in the CPU. Before doing this be sure to turn off the computer. Just remove the network card from the slot then re-attach it back. Then restart your computer under Windows 7.

Check again if Windows will detect the device. If it still did not detect the device, turn off the computer again then transfer the network card to the other available slot. Then start again the computer in Windows 7.

Do this until Windows detects the hardware then install its driver back.

You may also check if the network card’s driver is fully compatible with Windows 7. Check the system requirements of your network card. Maybe this is also one of the reasons why your network card is not working.
