My PC shuts down by itself gracefully. When it's turned on, it works just fine but only for 3 to 4 minutes. And then, it tells itself to shut down.
Initially, I thought it was due to overheating.
Decided to open the chassis in order to be able to hear any loud noises, and what I found is that my PSU was generating some noise during reboot period and then went a bit quiet after loading the OS (linux - Ubuntu). After a few minutes, it shut down itself. And if I turn it back on after being shut down, it will start again with no problem. It turns itself off again after a few minutes later.
Just wondering if this is a sign that I need to replace my PSU. My understanding is that if this issue was caused by PSU, it would not get started in the first place?
I didn't find the right solution from the Internet.
