I would have looked at it too before, but I struggle with these kinds of things now. This PC I bought rather than building myself, because of the challenges I have with that kind of learning. I am not "not" technical, but not as technical as I once was :)
Wasn't heat and all PC components were performing well. Very strange.
That's good you have that fear, because if you didn't, you'd be a whole lot more vulnerable.
Fear is good. Most people are scared of the wrong things.
