    It's possible you have bad card. The unfortunate truth about computer components is one day they can be working fine and the next they are completely dead without any warning. From what you're describing, something went wrong and your card is completely dead now.

    Is it a PCI Express card? Some of the cards have their own power connector that has to be plugged in to the motherboard. If that's not the case, do you have another pci-e slot you could move it to. If you do have another slot and it still doesn't work then the card is probably dead.

    1. Turn off and disconnect the computer.

    2. Open it up and take out the graphics card.

    3. Re-Seat (re-install) the graphics card in the pci-express slot

    4. Disconnect and reconnect any power/fan/cables you have going to the graphics card.

    5. Restart computer and update drivers from Nvidia.com

    Your video card most likely burnt out. There might have a been a power surge through your PSU. You might be able to get a replacement card from MSI and tell them that "it just quit working" via an RMA.

    Out of curiosity, do you have your computer hooked up to a surge protector or UPS? If not, I suggest at least a surge protector be used in the future.
