I recently purchased a bunch of computer components, all of which were purchased brand new, and I assembled the computer. The computer functions just fine for the most part, and I installed Windows 8.1(from the Dreamspark program), but I'm having two big problems.
Firstly, when I plug in a Logitech headset(speaker/microphone jacks, not USB), audio plays through it fine, and the computer recognizes that there is a microphone, but it doesn't pick up any audio through that microphone. If I look under recording devices, I see the microphone listed and available, but the bar on the side that indicates sound doesn't react to any sound. And if I try to use the microphone in a program like Audacity, it picks up no sound. The headset works fine on my laptop(also Windows 8.1), but I don't currently have another microphone to test if that works on the computer. Since it's the microphone jack, I'd imagine it shouldn't need any drivers or anything.
Secondly, a Logitech Gamepad f310 doesn't work either. When I plug it in, it plays the "device recognized" sound(sometimes), and I see "USB controller"(or something like that) listed under devices. Depending on whether it's set to DirectInput or XInput, my PC either recognizes absolutely no button presses from the gamepad at all, or recognizes the A/B/X/Y buttons, but nothing else. Since the gamepad is USB, I figure it could be a driver problem this time, does it sound like that might be the problem? If so, where would I find the driver? The PC has no Internet connection, by the way, but I can get the driver on through an external drive if I need to. And if it's relevant, in the past, when I've tried to use certain programs, I've gotten errors such as "xinput1_3.dll is missing from this computer." even though the computer claims it has DirectX11 installed.
