Hello I am Currently running a dell XPS 8700 equipped with a graphic card of Gtx1060 but recently I have been having no monitor signals pretty frequently , usually when i am gaming or in windows . My monitor was at first not starting up so I had a new monitor to try to fix the problem. However , The problem still persists whenever i open games . Whenever a no signal pops up i have to restart my computer , I also have trouble booting up to windows as I lose signal whenever i am booting on halfway . I have tried testing multiple DP cables to connect , check that my ram is working fine and there were also no loose cables . Now i am not sure whether it is a graphic card problem or power supply unit issue , please help!
