I've had this PC for a year, the problem is that my PC shuts off when gaming, I play a game for atleast 20 minutes and bam it turns off, the GPU temp rises to 62C and stays there, CPU goes around 57C-64C, while I play I can just hear the PC fake shutdown twice, like you can hear everything stopping and starting again, but it just keeps working and it shutdowns the third time, I can also hear fire type noises coming from the computer, like if you've been close to a fire you'd know what I mean, also don't joke that theres a fire flaming inside, what I've done so far is I changed the thermal paste in the GPU and CPU which helped the temps, I've added 2 case fans, I've tried cleaning the PC and I tried using old drivers, nothing fixed the issue, the only thing that fixes it is underclocking it by a lot, what could be the problem???
