I built my first PC in late 2013 (Haswell i3). In late 15' or early 16' I started having trouble. My PC will try to turn on and then turn itself off over and over every time I restart. I have to unplug it and plug it back in, and it works fine. It only does this during restart. I tried some basic troubleshooting and nothing seemed to work, so I chalked it up to a power supply problem. I've lived with it since.
I don't tax my PC hard and decided to upgrade rather than build new. I figured I could survive with this system for a few more years. I bought a Haswell refresh CPU and enough RAM to max out. I figured I'd pick up a modular PSU as I can transfer it to my next build and perhaps it would solve my issue. I just installed the PSU (nothing else), and tried to restart. Same issue. I'd like to get this fixed prior to my CPU upgrade because I need to update BIOS to accept the Haswell refresh. I'm concerned about restarting after BIOS update.
Any thoughts on how to solve this?
