I forgot to say that when I rebooted it, the old problem returned, the fans were going full blast and nothing on the screen.
So we took the battery out and put it back 10 mins later and rebooted and went into Bios and reselected, rebooted and now everything ppears to be fine.
I think maybe it was headed towards this before it failed, maybe the F-Security was just a coincidence.
It was running hotter and was slowing down leading up to this. :?
