Did you optimze Windows for use with a SSD? Here's a link to info that might help:http://thessdreview.com/ssd-guides/optimization-guides/the-ssd-optimization-guide-2/
Is your ssd plugged into the SATA port marked "SATAII0"? Your motherboard is two years old. My memory isn't the greatest but I seem to recall the boot drive was supposed to be plugged into the SATAII0 port on the motherboard. I might be wrong. Also check you SATA cable. If you have a spare cable try swapping cables.
