I got my new parts the other day (eg7650 cpu, gigabyte ga p35 ds3l mobo, corsair 620hx) and today I went about removing my old mobo/psu/gpu etc. Installed everything, seemed to go smoothly, no issues getting anything in there and connected. Replaced the cover, got my monitor/mouse/keyboard plugged in, plug in the power supply, turn it on, and hit the power button. Nothing. Turn it off, unplug, open it back up, check the connections, everything looks fine so I try switching the power/hdd/power led wires to see if i had them the wrong direction, close it up and try it again and same thing. As far as I can tell all my connections are good but I can't get it to start up, I don't get any response whatsoever, anyone have any ideas?
