community i need some help...

ok, so i play other games besides league, not many problems( ie this error i keep getting constantly whilst playing leauge) once in a while it happens in WoW but every single time the past week after about 5-10 min of game play i get a "No signal" error where my screen goes black, i can still hear the back grounds and things, yet have to turn off the comp, and turn it back on for the screen to come back. I've checked my PC specs they are good, have no issues on most other games or at least get a good hr or 2 before it happens... yes cords and parts are good, but it seems to have gotten worse with the windows 10 update, and i cannot communicate via League chat anymore from it. I've tried to update driver and it say that the latest update it has no compatible graphics card.... its just really weird that it really only dose this to league....any help would be very appreciated...
