Okay I had to do some work inside the pc so to make some space I disconnected the power wire to the cpu and forgot to reconnect it. Started up the pc and nothing showed up so then i remembered to connect it. I turned off my pc by disconnecting the power to the whole pc because it wasnt turning off any other way. Then i reconnected the power to the cpu. BUT I reconnected it the wrong. I turned it on but nothing showed up again. Then I fixed the way it is connected and it still wont turn on. Fans work and everything works just nothing shows up on the screen. Did I screw up any of the parts? Only parts I can think I might have screwed up are the cpu, the mobo, the hard drive or the power supply
