Problem description: My computer started doing this about once a night for the past week but is now crashing VERY often. The monitor(s) (one or both depending if I have 2 hooked up) go black and lose input but the computer keeps running. It seems to be running fine still after the crash ie. if twitch or some video is playing in the background the audio keeps going normally. This led me to believe it was almost certainly the GPU (wrong). I can only get back to desktop by hard rebooting (holding power until it shuts off).

Attempted fixes: I replaced my GPU with a brand new one.(GTX 970). I have checked all temps that I can with HWmonitor and all seems fine. The only thing it doesn't seem to list is RAM but I did touch the ram after a crash and it did seem very hot. Could this be the cause? The other thing is the machine is old and I have never replaced the thermal paste on my CPU but the temps read okay (60C max). Can the computer still function (sound, power etc.) if the CPU crashes? Other culprit I am thinking is PSU but again would the rest of the computer continue to function in that case?

Recent changes: Added a new monitor because my old one was seemingly dying. It would lose signal and then come back every so often. Perhaps this was actually not the monitor afterall?

I have Googled and read the FAQ: Yes, all advice pointed to GPU but this is 99.999% certainly not the case.

What's the brand and model of your power supply? I would try resetting your CPU back to stock speeds for testing as well.
