As of the last two days I've had an issue where upon starting vr for the first time that day, I'll get a complete shutdown. Upon it shutting down it'll refuse to power on until I hit the psu off switch and turn it back on, where it'll boot perfectly fine. It will also run VR fine after that from what I've seen so far.
I'm guessing this is a PSU issue, based on how it's shutting down and refusing to turn back on, but I really hope it's not, anybody have any other ideas for what might be causing it?
