It has been a week since I made sure that the two ram cards were securely in their slots on the motherboard.
I honestly saw nor felt any difference when I inspected them and wiggled them around.
When I last posted, it had only been a couple of days and things were still working correctly.
I think it is safe to say that problem has been fixed.
The system has been closed back up and put back in it's spot beside the table.
It took a while to figure this one out, and it was so simple a solution.
Keeping things simple is always the best!
