Some background knowledge for right now, I bought this computer in mid Feb, 2015, and its worked fine since. (Custom built) However, all of a sudden it starts messing up and won't turn on again.

Alright, so I was just playing SMITE with a couple of friends and we were talking on teamspeak, when I left the server, I unplugged my tablet, and then plugged in my wireless headset t charge it. (I was also charging my tablet). All of a sudden, a couple seconds after plugging in my headset, my monitor goes grey and displays the message "DVI - Port Missing" or whatever. So at the time my screen goes grey, my mouse turns off, but my keyboard's lights are still on. I just thought this was some weird unusual thing going on, so I hit the power button but my pc wasn't turning off. At that moment, I looked inside the pc (my keyboard was still lit) and saw all my fans were off. Then, being an idiot, I thought I could fix this just by resetting the power supply. I went to the power supply, pressed the flippy button thingy to the O, flipped it back to I. I then went the front of the pc again and then pressed the power button, and it wouldn't turn on. No fans, lights, nothing at all. The power outlet is perfectly fine, I've tested it with lamps/phone chargers/etc. When I press the power button, nothing happens at all. No lights or sounds, and the PSU fans don't even spin. I've checked the other components of my computer (cpu/mobo/gpu) and they all look fine, but honestly I don't know what a broken one looks like.

My question basically is, do any of you guys know a fix? Ask any questions you'd need and I'll try to respond asap. Otherwise, this sounds like just a broken PSU. I also rarely turn my PC off, (usually for updates) so thats probaly the main reason my pc died. Please, if you know a fix, or a solution other than buying a new PSU, please share! However, if you do believe that it's the broken PSU, please recommend me a PSU that doesn't burn out in 9 months.

PC components-
Mobo - MSI h87 PC Mate
RAM - HyperX Savage
GPU - AMD R9 290
CPU - Intel 4460 (non over clocked, stock cpu cooler)
PSU - EVGA Supernova 750W Semi-modular.

I took it to a repair shop earlier today, and they said that the part where the PSU plugs into the motherboard was shorted and bent, so I ordered a new one. But thanks alot for telling me how to test my PSU!
sounds like a new power supply is needed. to test the psu, disconnect all power cables coming from the psu to the motherboard, drives & videocard. with the psu plugged into the wall, use a bent paper clip or needle nose pliers to short the green & black wires on the big motherboard connector from the psu. the psu fan should powerup & if it doesn't then get a new psu.

Thanks alot! Ok, so the fan on my PSU spins, with the paper clip in the green and the other end in the black. But then, I plugged the wires back in the mobo and HDD, but my fans on my PSU didn't spin. Then I shorted just the plug that plugs into the mobo, and the fan spun fine, and I could even hear my HDD spin and could open the disk reader. Does anyone know a fix?
