I have a problem with my P50t A119, Windows 8.1, all up to date: After a couple of minutes the message "there is a problem with the cooling system" appears.
The CPU/chipset fan is not working at startup and does not start at all. I replaced it with an identical model, but the Problem remains. Even after power on the fan does not work.

Anyone with the same Problem? Ist the Mobo wrecked? Or can a Windows update interfere with the BIOS fan operation?
