First of all I don't know much about computers. I just installed a fresh version of MS windows and I dont think my video card is working anymore. I think its a Geforce FX 5200 but Im not sure. Also I bought new speakers and I cant get them to work. When I tried to play an audio file windows media player said "Cannot playback the audio stream, no audio hardware is avaliable or the hardware is not responding". I searched for my card and my speakers in a hardware list i found somewhere in my control panel but I couldnt find them. what to do?
