This is my first time using a m2-atx (ist carputer!), I am using an Asus ionatx-I mb and I have room for 3.5 desktop dvd drive, I am powering the drive from the pwr harness provided with the M2. I have the mb powering up fine but when i open the dvd drive to load the system disk to install operating system everything shuts down. Can someone help? Thanks
