Pc has been working flawlessly for 4 years, I came home to my pc running (windows 10 turns on pc for whatever reason sometimes) and the monitpr has no signal. I decide to use the reset button, and the pc refuses. Lets me know through beep signals though, that the processor failed. A forced shutdown and restart lets it boot, and works until I login. 10 seconds after the monitor looses signal again. Same result after 2 more tries.
