My brother and I built this computer six months ago. The problem didn't occur until a week ago.

What is the likely problem? Any solutions?

It depends on your hardware. It could be a PSU issue or if you have a certain CPU, it could be overheating and turning itself off.

How do I differentiate between PSU Issue and overheating CPU?

What are your system specs?

Also, you can download temperature monitoring tools for your GPU and your CPU. Your GPU could be overheating, shutting your computer off, or it could be your CPU. Run the temperature monitoring and watch them very closely, writing down the temperatures that the computer shuts off at. Make sure you log the temps in Celsius too, not Fahrenheit. It'll save us (me) some math to convert XD.
