I recently just got a new case for the wife and graphics card(1070), the case is on the cheaper end (raidmax neon). during installation and my first attempt to turn it on worked, unplugged in walked over to the desk plugged everything in and no power. took it back to work desk and figured out the PSU is toast for what ever the reason is. will not power up the motherboard I had an extra 850 watt and hooked it all up, it powers on flipping the switch on the back ( like automatically without pressing the power button) when I shut it down from the start menu I cannot turn on the PC with the button, and it will not start flipping the switch on the back, I have to unplug the button and short it out to start it back up. any clues as to what it might be?
