Question GA-78LMT-USB3 not booting when port 4 is used for a drive.

When I put 6 sata drives to use, it will not boot to windows. I normally have the sata port 4 used for my esata on the front panel and 4 drives and a dvd burner. I pulled the connector and moved my 500 gb boot drive to it and it wont boot. Put everything back and it boots. The Bios has the latest update, running win 7 64 bit.

The drive you're moving around, does that have the OS on it? If so, that drive should ideally be on the first SATA port. In this day and age, I'd ask you to ditch the ODD. What is the make and model of your PSU and how old is it?
