I have two custom built computers that I use frequently, and they are both in different places with different parts. The first one¹ recently shut off while I was playing games and now it wont POST, so I started using my other computer more. A day later the exact same thing happens to my secondary PC². The first time it happened, I was playing Dishonored 2 and my screen suddenly went black and I heard the fans stop spinning. When I went to turn it back on, I heard all of the fans spin and the lights come on (and stay on, they do not power-cycle), but there was no beep from the case speaker and no display on the screens. I restarted it again, plugged it in elsewhere, tested all the ram, removed the graphics cards, and even unplugged every non-essential fan and light but it was all to no avail. I used my other computer for the rest of that day trying to come up with a solution as well as today before it too turned off in the exact same way, this time shutting off the second I opened Dishonored 2. Because of the nature of the issue, I feel like Dishonored 2 is a coincidence and I believe that I have it narrowed down to a CPU or motherboard issue. Short of replacing the hardware, I am out of ideas. I was going to use the second computer's motherboard to test the CPU, but because that one just died too, I don't know how else to test it. Please let me know if you have any suggestions.
