I recently got an Asus Vento 3600 case and moved all the parts from my old case to this one. I also added an extra seagate 250GB hard drive and upgraded the psu to 550W. But surprise surprise when i turned it all on there was no picture on the monitor but also no POST beeps. Everything was working perfectly before i moved all the parts. I took out the RAM and powered on the computer, it beeped so i replaced it again but still no luck, i then took out the graphics card and turned it on and got no beeps again. Also could someone who has this case tell me how to connect the case to the front header properly.
