I bought a warranty and my wife says she did not cancel it and I know I didn't cancel it.  It makes a long continuous tone as if it is memory-related.  I  changed out the RAM but got the same result.  It's just plain dead and won't do anything.  Only my wife and I have had access to this piece of junk and we both claim we did not cancel the warranty.I'll probably have to rebuild it from scratch.  I'll have to buy Windows 10, a new m.2 memory module, and who knows what else to fix it.  It's almost worthless.  All I have is the case and physical hardware.  Even the power supply is suspect.I'd like to know how my warranty got canceled.
