So as the title suggests, when put under any noticeable load (launching just about any game under the sun) my entire system crashes and then instantly reboots.There is no BSOD or error message, just instant reboot. I have already checked thermals, and cleaned out all the dust. I have also re-seated my GPU and RAM. I have done a fresh install of windows 10 Pro 64-bit and nothing has changed. I only have one idea. My power supply is really old so it may be failing. If anyone can identify this problem before I start replacing hardware bit by bit then let me know.
