    Yesterday, I was on my computer, when I decided to unplug a USB connection to my printer off from a USB port at the top of my PC. Upon doing so, my monitor went blank, and I think I heard the fan levels increase. My keyboard lit up all of the lights, which only ever happens while the computer is booting up.

    I waited for a while for the display to return, but nothing happened, so I attempted to manually shut it off by holding the power button down. Nothing happened. I managed to unplug the cord, to turn off the PC. Upon plugging it back in, the PC would not start.

    So far, I have concluded that, the power socket and the cable both are fine. The GPU LED light is also not on. I checked the connections to the motherboard from the power supply and they seemed all in place. I also ran the 'paperclip' test on the Power Supply, which worked. I moved the RAM sticks to different slots, and even took out the memory, but didn't hear any sounds or notice any power.

    Interestingly, the LED power light on the case seems to occasionally work. Hoping that the issue is not the motherboard.

    SPECS:
    Motherboard: MSI Z97 G55 SLI
    POWER SUPPLY
    Cosair CX650

    All help is appreciated. Thanks

    If your mobo didn't create beeps when memory was removed, then ur mobo is bad. It's possible it was shorted out somehow when the USB was removed?
