Hi everyone. I'm new to this forum, I need some help. My brother and I were both playing together in a game. Right in the middle of it, his computer randomly shut off. He said he heard a "pop" noise and then it shut off completely. It hasn't turned on since.

I'm not sure what his specs are in detail, but here are some things to note:
- He has a GeForce GTX 960 and a 500W power supply.
- Computer is pretty low level and only has 2 fans, so it gets very hot.
- When the computer shut off, the peripherals plugged into the computer were still on.

I have already confirmed it shouldn't be the power supply causing the issue (I think), because the peripherals still light up. This should also rule out a faulty outlet or power cord, however I could be wrong, so correct me if so. I have also been looking for components on the motherboard that "look fried", and I am yet to find any.

If you have a solution, please reply and let me know, it would greatly help!
 
As a PSU puts out various voltages +3.3V, +5V and +12V it may appear that the PSU is working correctly but it is not, any significant drop of any output can prevent the system from booting up, the other scenario is a significant increase in the output which can be worse as it can fry one or more major components such as the MB, CPU, RAM, add on video card etc.

Please be aware that there are no user replaceable parts in a PSU so a bad one should be disposed of in a responsible manner and any type of conclusive testing will need to be done by a suitably trained Tech who has the required testing equipment and the relevant knowledge as to how to use it.

Post the brand and model name or number for the CPU, MB, the RAM (including the amount) add on video card and the PSU (power supply unit) providing these details will enable folk to better help you.
