So I was cleaning out my fans with some compressed air, and I noticed that on my power supply there was a 115V / 230V switch. My tired mind thought "More volts = more watts" so I flipped the switch, thinking nothing of it. Upon plugging my computer into the wall, I turned it on. When it first booted up, there was a loud hissing noise (which I dismissed, seeing as I have pretty low quality fans.), and after multiple seconds, I heard a pop, sparks came out of the PSU fans, and my computer shut down. Now, even with my switch on 115V, my computer will not turn on, and I'm worried other components might be broken. Can someone tell me if I need to replace anything?
