Question CPU fan spins very fast and I lose video signal. It basically crashes

Jul 18, 2019
I have had my computer for about a week now and haven't done much with it yet. Yesterday I played for about 5 hours and the fan spun very fast and I lost video signal, my friend also couldn't hear me anymore and after a few seconds I lost audio. I turned it off and tried to play and it happened again. I came back hours later and tried one more time and the LED on my cooler mostly stopped working. Someone suggested that I replace my thermal paste and I did so. The LED on the fan didn't work but still spun. I played a game for a little bit and joined a friend, immediately when we got in a game it happened again.

Edit: Part list -
Also the LED Debug on my motherboard doesn't light up at all
