I created the Partition, I then set the power management to sleep
after 2 hours. It was not set to sleep at all, so I am not sure what
it was doing. It just turned the monitor off and locked up eventually

When I got up this morning, the pc was "sleeping" I hit the power
button and it came right up. So I guess this is resolved. Thanx for
all the help
