I have an Aspire E5-511 notebook. It is a great computer except every once in awhile the fan will go off at high speed and then my system locks up. It doesn't matter what I am doing. It has done this while surfing the web, using Photoshop, or Open Office. The only way out is to shut off the computer. There is nothing in the event logs - only that the computer was shut down unexpectedly. Anyone have any ideas?
Thanks,
Deby
