My computer will randomly shut down, usually it's while playing a game or doing a high processing task, and the last thing I will hear is my loud fan. But sometimes the fan won't be too loud and I'll just be doing some basic internet browsing when it abruptly shuts down.
This has only started happened recently, when the only thing I have done is add more fans.
Is there a way to find out for sure if my computer is overheating?
Is it possible for me to save temperatures to a text file so I will know the temperatures right before my computer shuts down, to find out if it really is overheating?
