I have 2 microphones and my computer won't pick up either one of them. When I bought my manufactured computer the speakers and microphone from my HP mx70 monitor would not work. So I plugged in some old speakers and they work, but I went to my volume control and made sure that the microphone wasn't muted and the volume was turned up. After that I went to the Control Panel and went to Sounds... then went to Voice and tested the hardware, but my microphone still wouldn't pick up. I figured that must also be because I don't have an HP tower anymore so I bought a new microphone (Labtec desk mic) and my computer won't pick it up either. I have a Nvidia nforce sound card (don't know if that helps, but I thought I'd mention it). Oh yeah, I can't seem to be able to contact the man I bought the computer from. Is there any hope for me?
