I have never seen a bad battery on a new board before....
I have heard very bad things about the Agility 3. I think one of our regulars here got 3 bad ones in a row or something crazy like that.
Are you overclocking at all?
Run Memtest to rule out bad RAM. What timings are the RAM running at?http://www.memtest.org/
What power supply are you using?
Try a diffrerent SATA port for the SSD.
