Recently my card have been working fine and I was playing LoL for a few hours and I turned my computer off since I'll be eating my lunch. Then after eating I went back to my computer, turned it on then for some reason there is no display but e components are working. So is this a sign of a dead graphics card or what? I tried reseatting the card and replacing the power cord. So yeah, any suggestions? I don't know if the store where i bought card would replace it with another one since they are only a retailer. My card is a MSI GTX560 Ti Twin Frozr II.
