I have a rig with a ryzen 5 3600, x570 mobo, 2060 super, and a 600w EVGA PSU running Windows.
About 3 days ago I rearranged the room where my setup is (not sure if related or a coincidence) and since then, whenever I turn my pc on, it’s only a matter of time before it shuts itself off again. But it doesn't turn off completely when it happens, it’s more like it just loses power for a split second. Just long enough to reset the system.
Whenever it does happen I do hear what sounds like a switch or relay being flipped somewhere on my mobo. I’m unsure of what it even might be and I’m also unsure of whether I'm hearing this because it’s turning off or if it’s turning off because of whatever is causing the sound.
ive tried changing PSUs, I’ve disconnected and reconnected all the headers and connectors, I’ve reseated my CPU, I’ve tried booting without my GPU, tried disconnecting my extra drives, all with absolutely no change in behavior so I’m beginning to think there may be a bad capacitor or something. I’m not sure if it’s related, but I also have a problem with my GPU fan going to max whenever my system goes to sleep or gets turned off by the initial problem.
I’ve had my system build for a few months without issue up until not and any help would be greatly appreciated.
P.S.
After typing the above but before actually making this post, I decided to try a few more things, I tried to reset the bios by removing the CMOS battery and unplugging everything and letting the power drain. I’ve kept the battery out and it was working for a while before it cut on me again.
UPDATE: after talking with an EVGA rep, I happened to mention that I looked at my PC health in my BIOs and saw that my 12v rail was reading something like 12.6xxx, he said that was outside of spec so it is most likely my PSU causing this issue.
