A few days back I had a display problem with my HP Pavilion DV4 laptop. I took it to a service centre and they told me that some NVIDIA chip on the motherboard needed to be replaced to fix this.
After replacing the chip, the display problem was fixed but the fan started running at high speeds – even if there were no application running. The fan is noisy, its speed does not drop even little bit but remains running while I use the laptop.
When I asked the service centre guy, he said the reason was the new NVIDIA chip etc. What could be the cause of this problem?
Is it because of the new NVIDIA chip installed on motherboard? Could it be something different?
