Hello, I just built a new custom PC; everything is connected but it won't boot but instead make a high pitch sound. I did try to plug in the VCard, CPU, 1 stick of RAM and the power supply onto to the motherboard on a cardboard box and it seems to work fine but when it's on the case, it still has the same effect as before, no booting and high pitch noise. I also removed any extra standoffs but I still think something is wrong with the case or the motherboard. Any suggestions? ;( GIGABYTE GA-970A-D3 AMD 9 Series FX Motherboard AMD FD4300WMHKBOX FX-4300 Four-Core 3.8GHz AM3+ Processor Coolmax ZU Series ZU-800B 800W Power Supply G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 Corsair CC-9011013-WW Carbide Series 500R Mid Tower Gaming Case If you need anymore information, please ask.
