My daughter's computer which I built for her 2 years ago is deciding to turn itself off constantly. My first guess was there was a fan not functioning which was causing overheating and the sensors are just preserving the PC by shutting it down when it gets too hot.
It was off most of the day and as we turn it on, it will shut itself down before it even gets to start booting Windows. And repeatedly shut itself down at different points. Yesterday it was getting to the desktop sometimes and then turning off.
We have taken it apart and cleaned out the dust and things which we are pretty good at keeping up on, but could be better. all the fans are working just fine and it seems like there is not an airflow problem. also the case and PSU all feel pretty cool to the touch.
Looking for any ideas on how to remedy this or anything I can try. My options are limited as I cannot even get it to the desktop now.
I appreciate any help that can be offered.
