SO I have a 600gb raptor drive for my operating system and 4 2tb drives connected by sata and esata for storage. Recently my computer processor would spike to 100% on all four cores and the computer would become responsive. Trying to restart the computer would freeze at the Win7 splash screen . After trying a million different things turning off the port for one of the drives on the motherboard allowed the computer to run normally. Two weeks later the computer stalled at the start up again and disabling the esata port from bios allows the computer to run normally. I have taken one of the drives in question out and put it in a dock and it seems to run stable. Any ideas? Motherboard? Cables? I reformatted the drives and it seem to help for a short time but then everything went back to the way it was before.
