Hi guys! I have some trouble with my Acer Aspire for a few days now... If I'm watching online videos (mostly when it's buffering), I can only watch a few minutes and then my computer shuts down by itself with no error message, not even in event viewer! I tried different things, but I don't know what to do anymore. It does the same in safe mode too! I have an updated video card, I have all required codecs installed, including the latest Flash version. I am beginning to think that is a fan and temperature problem . Do you know any good software that monitors my PC's temperature or things related to the fan in real time as I play a certain video? Or you know some other things that could cause this problem?
