1) There is no way you are getting more than 70 nF capacitance from twisting a few inches of wire. Not even 70 pF. 70 nF is HUGE!
2) All signal pins on all devices will have some value of capacitance that renders them inoperable. The value at which things fall over is usually related to the signalling speed, and sometimes related to the driver design.
3) Power pins are not signal pins. They need capacitors.
4) If rebooting your computer addressed the problem, then your circuit was fine all along. But it's hard to see how it could have had any impact at all. Very unusual. I think there's still "some 'splaining to do"...
