Hello, i have a GTX 750ti SC and it will either cut signal to the monitor or turn the PC off while the case lights are on, i have checked and it runs from 30-40 degrees, i also switched out the card for an old GT 730 and it stopped, the card didnt do this till today. It only happens while i game on it
