HP OMEN fps drops on every game.

Product Name: HP OMEN Notebook - 15-5001na
Operating System: Microsoft Windows 10 (64-bit)

In the summer, I have bought HP Omen which I thought handle every game which was released. Firstly I have installed counter-strike global offensive in which I experienced fps stutters and drops. Then I have installed GTA 5, the game has recommended high graphics, but I customized it and set to normal. After 5-10 mins Omen has started overheating and the game suddenly became unplayable. Now I am playing World of warcraft on LOW graphics which was recommended to play at HIGH, but after 1-hour laptop is starting to overheat and I experience fps drops.


Yes, I have updated all (Windows and PC driver)
Yes, I am sure that PC detects Nvidia graphics card.
Yes, I have jumped on windows 10, but nothing has changed.
Yes, I have a desire to commit a suicide.


Please help. It can be treated as one of the worst nightmares of my life.
