Ok guys its kind of similar but im not quite sure. Im currently running a 150gb Raptor X and the 850w pro PSU from cooler master. When i first plug in my computer everything boots fine, then ill shut down and leave it plugged into the outlet. Then when i try to power it on again, my raptor x spins then stops then spins then stops. It just keeps on doing this and nothing comes up. I have to unplug the PSU and and wait for the red LED to disappear then plug it back in and everything works fine. I know its similar to issues you all have but would my situation qualify as well? Any help would be appreciated.
