After cleaning Asus K53SV fan always on and GPU not recognized

[Giovanninowawa]

Hello everybody, first question on the forum from my side!!!

I decided to clean my Asus laptop from dust but when I reassembled it the GPU is not recognized anymore and the fan is always on (even before the boot) at the same speed (with temperatures around 30-40 c). This is not the first time it happens that the GPU is not detected: first time it was enough to open the pc, put again the thermal paste, close it and tatam: it was in the device manager. Now it doesn't work :-(

I tried to find the fan with speedfan but nothing...

Is there some saint that can help me? Thanks!!!

I also noticed that the fan, which speed is costant, starts after 1 minute and in case I swith the pc off, starts immediatly, so I think the fan is connected to the sensors!

Do you think that the fan works so much because of the temperature?

Do you think that the GPU may be not recognized because of the temperature?

Thanks!!!
