I built a computer in 2017 and over the past 6 months I've had a lot of problems with it. I used to leave it powered on all the time and occasionally when I'd go to use it I'd find that it wasn't working, it would be in a half powered on state where it wasn't booted and I couldn't power it off by holding the power button. I'd have to pull power and wait a minute before it would power back up. Over the course of the past 6 months I gradually replaced every component in the computer (motherboard, processor, memory, video card, etc). Lately it got to a point where I couldn't even reboot it, it would never complete the reboot without pulling the power cable for a minute. Finally I tried swapping the power supply out and it's been fine for the past two days. Has anyone had an issue like this before? Is there any troubleshooting steps that I can do on the power supply or should I try to start an rma?
