So me and my brother recently got a new rig for gaming after years of pleading and begging. With the help of my dad's friend we assembled a pretty good rig. However, nowadays, especially sometimes when my brother plays Minecraft, the screen sometimes flickers a few times, goes black and then we see the blue screen of death. It's not happened to any of the games I was playing, but the screen flickers sometimes. Its been three or four times its happened to my brother, though, so we're really starting to get worried. This cost quite a bit, and we don't want it to crash in less than a month. I would really appreciate it if you guys could help us find out what's the problem.
