ROFL. You guys are crazy. You don't need to replace your power supply ASAP. Worst case scenario, you'll start getting BSODs more frequently until your computer either won't power on or will power off randomly. If you're worried about a power surge to your components, I doubt a failing power supply would be able to create a high enough voltage shock to damage components unless it was seriously faulty. I'd say replace your PSU if you keep getting them, otherwise don't worry about it. Not everything works exactly the way it's intended to 100% of the time.
