Error Message: Primary Slave Drive – ATAPI Incompatible

So I recently switched towers and now, all of a sudden, I’m getting this error message as soon as I boot my system. The error message reads “Primary Slave Drive – ATAPI Incompatible”. This has really been frustrating since there’s NO Primary Slave Drive even installed in my computer!! I have one hard drive installed which is recognized as the Primary Master & a DVD Drive which is recognized as the Secondary Master. My old system ran flawlessly. I’m beginning to think maybe my motherboard is bugging out cuz I fail to understand how it can be telling me that a “nonexistent” drive is incompatible. Any suggestions??
