Driver not working for network adapter (Windows 7)

[jlens]

Hello guys I have a problem.  A couple of days ago my computer went to a blue screen for around 5 seconds and then it shut down.  It then showed me when  I turned it on that there was a problem and it gave me options on how to start it.  I chose last known configuration.  Ever since then my network adapter driver has been not working. That means I can't connect to the Internet. When I turn on my WiFi, the computer recognizes it but it says that the settings saved on this computer do not match the requirements of the network.  Even if I use a cable and I directly connect it to the computer, it still does not recognize it. This is very frustrating because I need badly for school.  Pls help and thanks in advance.

Do you have Anti-Virus protection?
In the device manager, are there any marks  that indicate a failed device?
Did you attempt to install the Wi-Fi again?
