HP India — Improper Functioning

Address:

Thiruvananthapuram, Kerala

I own a HP Pavillion 15-P077TX laptop with a Nvidia Geforce 840M graphic card. Within 4 months of purchase I faced complaint that system automatically shuts down within minutes after turning on the system. When iI showed it at the nearby HP service centre they examined and said that the Motherboard & Display cable his having complaint and need to be replaced. So I asked them change it since the laptop is under warranty and I got the laptop back after 10 days. Since then I am facing many issues like systems gets hang frequently, system does not restart, unable to apply any system updates, Nvidia graphic card does not function properly. So again I went to the service centre and again they changed the Motherboard and returned the same to me. But still I face the major issue with the graphic card which is not working properly as when I start any game it automatically goes into a grey screen with the message "Windows encountered an error and prevented this program from running". Someone please help as I spent 50K on this laptop and within 4 months of purchase I am facing a lot of issues. Expecting a favourable response.
