Hey this is my first home build and hence my first time dealing with computer parts so id thought i be extra careful and basically copy a video with a few adjustments to suit my specific parts. anyway onto the problem i test booted my computer with just the graphics card, cpu, ram and power supply plugged in however when i turn it on nothing appears on screen and i dont hear the single beep that the guy in the video does.http://www.youtube.com/watch?v=d_56kyib-Ls&feature=relmfu heres the video for reference and the test boot is around 15 min
