This only happens when my computer has been on for a while I will hear a ticking sound inside the computer. If I'm playing a high demanding game but not too demanding it will start to tick earlier than if it was idle. It happens every time. I'd say an hour after just browsing youtube it will start. I typically restart my pc or put it in rest mode and turn it back on right away. It solves the ticking noise for another hour or so everytime. Not just once in a while. It happens every time and I resolve it that way everytime. Started about a year ago. Anyone have any ideas?
