I recently added a SSD to my build and did a fresh install of windows on it. Without my regular hdd in, the computer boots and runs fine. I have it set up in IDE and when i add the 2nd hard drive, it hangs in the windows logo screen and reboots, then continues to cycle that way. The ssd is a samsung 840 and the hdd is WD 500 blue. In a gigabyte 970ad3 mobo.
