I purchased this PC less than a week ago, and it ran smooth, but now while playing Civ 6 or Final Fantasy 15, it will run for a bit, then crash. The the whole system will lock up with the screen looking like the image attached. If I leave it without a hard boot, it will go black, then come up to the log in to windows screen. Any ideas of what's going on? Or should I just take it back and exchange it?
