Long story short, my computer wouldn't turn on anymore after a hard reset. However, if I left it plugged in, it would spontaneously turn on but wouldn't POST. All the fans would come on, along with the lights. It wouldn't respond to the power button and I've checked all the cables along with buying a new PSU. My question is, could my motherboard have been fried by my old PSU? And is there any way to check this without buying a new one. Also, could my CPU, RAM, or Video Card have been fried too?
