I have an Acer M3802 desktop pc running windows 7 Home Premium. It is just over a year old and I have had no problems until recently when it just started shutting down for no reason. sometinmes it would run for minutes and others for about an hour or so. Its as though the power has been cut. i downloaded Speedfan 4.41 and it says that the temps are around 16oC to 48oC. I have cleaned out the inside and removed all signs of dust but it is still happening. Is this a heatsink problem or a PSU problem.
I would have thought that if it was a PSU problem it would be permanent? If its a fan problem where do i fit another fan
Anyway if anyone can help it would be much appreciated.
