My PC has been shutting down by itself (however its only when its idle) So when I don't move it for a couple of minutes (not when in sleep mode) So if I leave it alone for a while it just shuts down abruptly.

Sometimes the PC just freezes, but doesn't shut down. (usually happens when I don't move the mouse while watching movies/videos, or just leaving the PC idle when listening to music)

Is this a heating issue?

What is the time setting for your screensaver? Try a different one.

I have screen savers turned off.
Also I turned off sleep mode and display off modes just to see how long it would take for the computer to freeze.

Not sure if I am allowed to double post, but bumping here.
My GPU temperatures are stable at around 42 degrees Celsius and reaches up to 60 on a decent load
Core temps stay around the 25 area on idle and go up to around 45-50 on a decent load.

I don't think this is a heating problem, but I can't say for sure. Does anyone know why the PC may be shutting down or freezing?
