So the other day I was on my pc and it shut off, followed with some sparking sound and a burnt electrical smell. I assume it was the psu. So I took it out the next day and still has the electrical smell to it. Is that what the problem is? I hope nothing else went with it. Although I don't see why it would take anything else with it. Doesn't power on at all so I ordered another one. Less power so hopefully it will work. To put it back in where do the power cables go? I have no idea where any of them plug in except for like one. Plus pulling off the side panel closest to the mb something fell out of the side of it. It looks like a plate of some sort. Has 4 holes in the middle and 4 lines going out. Also has these standoff type things on it. What is that?
