When your power supply is literally smoking but tech support insists on running through their entire script before admitting the obvious.
This is the perfect illustration of the eternal battle between users who can see their computer is on fire and tech support who needs you to turn it off and on again first. Because clearly, the NOSMOKE module being incompatible with your power supply isn't as obvious as the actual smoke pouring out of your case.
And the final punchline? Microsoft can't help because NOSMOKE isn't compatible with your power supply. You don't say! Next they'll tell you that water isn't compatible with electrocution.
