   OK, looking forward to giving these a go. As-is, I attempted to rule out the   
   USB   
   stuff already (for what it's worth)...I removed ALL the USB drivers, that did    
   not appear to have any impact on the situation.    
      
   I also removed the 'Legacy' support in BIOS...that appeared to have hung my    
   system hard (no keyboard response, etc).

   Yes, tried this approach as well. Hard to tell if it had any impact, the total    
   number of complete boots today was about 2-3...so no different from last   
   night.    
   Mind you, I am trying such a large combination of stuff it's getting hard to    
   track it all...even when I'm writing this down...LOL
