I need to know where to begin to fix my pc because something must be fried. I had an iPhone charger cord plunged into the front usb of my pc. The other end that connects to the phone got stuck in the wall socket. Caused a spark and shut my pc off. Now it won't power back on. I don't smell anything burnt and after taking side off nothing looked burnt either. So is my psu bad or my front panel on my case? Or did I fry my MOBO or CPU.
