I have recently decided to save money and build my own computer. I purchased a case with a 420 watt power supply, a DFI Lan party kt400a, 512 mb ddr3200, and a video card and hard drive. The video card and hard drive are irrelovent for this question.
I switch on the power supply in the back of the case. The power supply makes a small hum for half a second and then stops. When I press the power switch in the front of the computer it does nothing. This led me to believe that my Leds, power switch, and reset switch were hooked in incorrectly. I reffered to the motherboard manual and found that they were hooked in correctly. I messed arround with them trying different directions to plug them in but the same thing happens everytime. Another note that may be important is that when I simply remove the switch it does the same thing.
Any advice would be beneficial.
