Well, as I was moving my computer to my living room, I plugged it in, and, as I set to press the I/O button, I accidentally pressed the voltage button 115/230 and then I heard a click, and a faint smell of burning. My entire flat's electrics went out, and after restoring, my PC would not start. I have tried turning it on/off, nothing happened.
My PSU, according to the handbook, has the following "protections".
Over voltage protection
Short circuit protection
Over current protection
Input over-current protection
I know I have f****** something up, but I hope that it isn't fatal to the rest of my components, as the power supply wasn't as expensive as my brand new GPU, which, luckily I have 28 day warranty on, so if it is broken, it's ok.
I'm such a t*** by doing this, I know, I am quite possibly the clumsiest guy in the world, but I would appreciate any help I can get.
Since I am no PSU expert, I think I may have failed to properly connect my hard drive, as it says there is no boot device selected when I start up. The monitor previously not displaying was due to an underpowered graphics card, which I then switched to motherboard graphics, and the monitor starting displaying "Select boot device" showing nothing below.
