Question Computer shuts down and reboots while gaming!

[MadMango69]

I just built this new PC and now while I game my computer will randomly shutdown and reboot while playing games. There is no frame drops and the parts are not overheating because I checked the CPU and GPU while gaming and the temp stayed in the safe range. I also don't think it is the power supply either because the light on my motherboard stays on so it doesn't lose complete power do y'all have any idea what component could be causing this or what the solution could be???
