Thread title pretty much sums up the issue. It started a few weeks ago. When I press the power button, fans spin up, it starts booting, then powers down after a couple seconds. Then it powers back up again (without me doing anything -- I don't have to press the power button again) and boots normally. Haven't had any other issues. I've tried googling but haven't really come up with anything. All the results are PCs that just shut down completely a few seconds after booting. I'm no expert, but it seems like a PSU issue. I have a Corsair TX850V2 that's about 14 months old. Anyone have any ideas? I'm stumped.
