Basically to make a long story short,

I have a computer built using the Asus A8N32-SLI board. It ran fine, and I want to add a second hard drive, and When i did, it BSOD'd on me (Looks like the ACPI BSOD it was a big blue flash) when I tried to boot up the computer, When I unplug the drive, everything is fine. both HDDs are SATA.

Any Suggestions?
