Hello all. Not sure if I should have put this here or in the building one but here goes. I built my own machine and it has been working great except for one thing. I have the LOGISYS Computer Area 51 CS51WBK Black Steel ATX Mid Tower Case which has the plugs for my headphones in the front including a plug for a microphone. Neither one of these work. I tore it back open today and everything is connected to the motherboard. Any suggestions? Also, my CPU is running at around 40 as well as my system, is that acceptable? Thanks
