[SOLVED] Did I brake my psu, or short circuit my motherboard?

[eydanlav]

Recently, I messed up. I just fixed my pc and I might have broken it. I was connecting my case fan after everything was powered off and tried to reroute my 24 pin cable to the motherboard. I disconnected it and realized there was no other way to route it, so I reconnected it. Now when ever I turn my computer on, it loads windows and lets me log in. Directly after I log in, my computer abruptly shuts off. No explanation from the computer (I mean like a screen saying it’s shutting down), it just shuts down like I am unplugging the computer from the outlet. I tried rebooting the system and once again, the same thing happened. What did I do to my pc? Plz help

You need to doublecheck ALL the PSUto motherboard connections and make sure they are correct and fully seated.
