Hi - I need some help figuring out why my computer is powering itself off after about 10 minutes of use.

History: System was ongoing for months no performance issues. The other day I powered it off to relocate and it wouldn't power back on. I noted that the power light on my mobo was flickering so I decided to replace my PSU. Doing so allowed the system to power back on. However now it only stays on for about 10 minutes regardless of what I am doing.

In addition to the power supply being replaced, I also replaced my MOBO and Video card. I did this both individually of each other and the behavior is still happening.

I don't get any errors or hear any beeps on boot and all the fans run no problem

Hoping it's not my ram, cpu or hard disks that are causing the problem but I really have no way of telling

I am running centos 7

Please advise on how I can resolve
