You are supposed to have enough so that the heatsink doesn't touches the heatspreader directly, because it would make short.
You said that happened before, when you unplugged your PC/power goes out. It sounds like the Power Supply is making ground with something in the PC and/or with the wall plug. Is it a cheapo supply? Try reconnecting everything or try replacing one component at a time.
