I took apart my computer about a week ago to put more RAM in and when I put it all back together it was working fine, and I was able to play games easy. The day after I started my pc while it was loading up the fans were spinning as usual, but when it hit the windows boot, they turned off and won't turn back on so when I get into a game the FPS drops and crashes because it overheats, I'm assuming from lack of airflow. One of the times it said that it was reading only the onboard graphics and that made the game crash as well. I took out the RAM and put them back in assuming it was being faulty but no luck. I even tried to take out the sticks and just have the 16gb I had before and still no luck.
