What pc build is better ?

Hello,

I am suspecting that it is shutting down because I haven’t been able to change the thermal paste that was pre applied into the CPU and the GPU before I bought it. Also, I am a noob when it comes to detecting the cause of the problem, but whenever I play games that require a bit of extra power like GTA V, NBA 2K17, and some other games that require a GPU, it automatically shuts down without any notice after a few minutes of play. Also, I decided to remove the GPU if the problem still occurs, but to my surprise, after using the computer without the GPU for almost 2 hours and gaming on light games that doesn’t require the use of a vc, it didn’t even shut down. So I am very much confused on what may be the problem, is it overheating or my GPU is dying (I hope not)? Thanks for your answers.

I didn’t find the right solution from the Internet.
