And that the XBox is fine it means there's something wrong with the PC. At just a few weeks old this is NOT YOUR PROBLEM to fix. Let the maker fix it.
I bought my PC pre-built a couple weeks ago and I had bad artifacts, what the tech guy diagnosed it with. So I had my gpu replaced, now im having a different issue with static flickering across my screen. Also the screen has gone completely black and I was forced to power off. Also im using a tv instead of a monitor, with a 60hz refresh rate. Is there something else that could cause this static or do I need another new gpu? (My tv worked fine for my xbox)
