Hey guys,
I have been getting a problem since I built my computer 2 months ago and on random games i get a black screen saying signal lost. It doesn't happen on say games like the division playing at max settings but on other games that generally have worse graphics such as overwatch or rocket league i get a black screen after 15 minutes and i have to reset my pc using the reset button.

I have a 550w power supply a gtx 970 and a i5 6600
im pretty noob at computers but any help would be appreciated, I have tried reinstalling drivers and checked if its a hardware problem and my gfx card runs fine in my friends computer.

Thanks,

Sam
