Yellow Question mark next to all drivers?
I just got a thinkpad T420. Had to do the whole bootable usb/cd with windows 7 iso writtten on it. Since im not that good with computers it took a while to figure out i needed to do that to get my computer to work. Anyways now after ive been able to get on the homescreen i cant seem to connect to my wifi. So i go to device manager and all my drivers have yellow question marks. This is almost guaranteed the problem i believe. I tried finding what i needed off windows 7 download support or whatever and ive been transferring the drives via usb and still my laptop cant seem to find the .exe driver files.
The Point: Can somebody help me find what driver files i need for the network controller and all. Im going to provide some handy info below.
