Serial Port Not Working

So I've been having a problem with get the port COM3 or over. I did everything in installing stuff. So I'm on the device manager. No ports listed. So I went to Action and clicked Add legacy hardware. So I click add hardware and click the ports section. There's a list of Manufacturers. I've click on all of them. But for this example I clicked Arduino LLC (www.Arduino.cc) and there's a list of Models so I clicked Arduino Uno. And I've try every different model for every manufacturer. So after I added hardware it says Arduino Uno was installed. The software for this device is now installed, but may not work correctly. The device cannot start. (Code 10). So now on the device manager I have to port that says Arduino Uno (COM3) but there's a yellow triangle with an explanation point. I just need help trying to fix this thing.
