So i got my bosses computer in my home shop. I dusted it out and did a fresh install of Windows 7 32-bit from the Vista that it had on it. The computer is a Dell Inspiron 530s. After installing Windows, the computer would not connect to either of my 2 routers. The green LED on the Ethernet port stays on and has another orange one blinking while NOTHING is plugged it... once i plug my cable in, ALL LEDs turn off... Please help. He needs his PC back for tomorrow and i am stuck. I tried driver installation again but there is no exclamation marks next to anything in the device manager.
