I'm from a 240v country and accidentally when I was changing my pc case moved the 240v and 110v switch, so when I was trying to turn on my pc the power supply just burned out so the question is that I don't know what is dead, so my motherboard is an ASrock 960gtm and my cpu is an AMD 6300fx the power supply is a Sentey 750w (generic brand), btw my gpu and other things like cpu fan are brand new so I don't think that they're the problem, I bought a new power supply an 850w EVGA Gold and it is still not turning on, then it came to my mind that the cpu or motherboard is dead, what should I do?, like I'm not sure in buying another motherboard or cpu.
