I have almost finished my computer and only need the garphics card for it to be complete. I installed the sony dru-810a last and decided to power up my system to see if everything turned on, fans etc. My questions is whether or not the dvd drive should open and close despite the computer build not being complete. Right now it does nothing, no lights and it doesent respond when i push the open/close button. It is hooked up to the motherboard and the power supply.
