I wanted to ask why my pc keeps going out when I play bigger games like Rocket league, Csgo, Fortnite, or Rainbow, but when I play smaller games such as Minecraft or anything else never do anything Lie? (If the pc goes out then the fan is always full and can't overheat.)
Is the power supply sufficient? Are you sure he does not overheat?
How can we give you an answer when we know zero about your Haedware. In other words, what kind of graphics card, CPU, motherboard, how much RAM, what kind of power supply?
My first guess would be that your power adapter is too weak.
It happened to my girlfriend sometimes, after she has built a Vega 56. After a stronger power supply was installed, the problem had been solved.
Yes, have been pretty sure the other day just tested it, pc is very warm but not overheated
