Welcome to SevenForums are you running 32 or 64 bit Seven?
Also when you go to device manager do you see any yellow exclamation points? If so could you please post a screen shot of your device manger so we can see which drivers you need.
You can find them here Sony eSupport - VGN-NS101E/S - Software Updates & Drivers
Just use the drop down menu and select which version of Seven your using. I could only find the model # VGN-NS101E/S.Thanks Fabe
