"I shut the pc down by pulling the plug. Maybe a cold boot could fix this. I turned it back on and still that Can't locate Signal or Find Signal in the middle of a black screen. So then I shut it down. Cleared the cmos on my pc. Then got it back up and running finally again. Now it is running fine."

The 'no signal' message was coming from the monitor. It was not receiving a signal from the computer's video adapter.

Since a cold boot followed by clearing CMOS memory solved it, I'd put my money on static discharge. Classic symptoms.

Were you wearing shoes on a carpted surface, by any chance?
