So I built a gaming pc about 3 years ago now, and I haven’t done much upgrading since. Recently about a month before my problem occurred, I bought a new power supply 750w with the intent to upgrade in the near future. (Have not upgraded anything besides that.) Gigabyte GA-Z97X-UD5H-BK motherboard, Corsair cx750m psu, Intel I7 4th gen, and a Radeon r9 270x graphics card. All these parts were bought and installed 3 years ago and have worked fine. So I was watching a movie on my pc when everything froze randomly. I figured I would restart it and it kept freezing sooner and sooner until it did what it is doing now which is it gets to the main page with the boot menu option and just restarts. Maybe 2 seconds and then it restarts. My problem is I’ve been reading similar posts and I can’t really find someone who has my problem with this happening seemingly randomly. Do I need to replace something?
