While i was surfing web my pc sparked and then shut off. naturally i assumed it was the psu and went out and replaced it only for the fans and leds only work for a second with no sound or boot up screen. i removed the sticks of ram one by one testing it after each one for it to only spin the fans for a second. i removed my graphics card and also tried booting it up for the same thing to happen. is there any way to test which part i need to replace?
