I have a Dell inspiron n5110 with a dedicated graphic card. My laptop was running fine till yesterday but today as i started gaming on my laptop it started to shut down. I tried many things but to no avail. Then i uninstalled my nvidia graphic card and tried to run the game again it wroked just fine but as soon as i installed my nvidia card and triend running it on it the laptop again got shutdown. i searched the internet and found a software named GPU-Z.
I tried to monitor the temperature in case the laptop shuts down due to overheating. The results were very weird under a VERY VERY small load the temperatures rose to a staggering 100c. and the pc got shutdown like it was doing before the exact same way. Even when only running Google Chrome using my GPU it goes upto 80c
.The GPU ideal temperature was around 58c.
Again i searched the internet and everywhere i found out was change the THERMAL PASTE as my laptop is two years old now and i do a lot of gaming.
I have not overclocked it ever. I have latest drivers and BIOS version installed.
Please guide me. I really need some help . Thank you.
