after 2 minutes or less of playing game the fps drops from 50-60 to 25- 20 randomly in any game
i tried many of solutions like:
-updating bios
-updating gpu drivers
-clean laptop fan and 
apply thermal past in CPU
but i notice that when the fps drops the gpu clock drop to 200mhz from 600-950mhz 
and the cpu power drops from 15what to 7-10

Thank you for posting on the HP Support Community.

Let's try this:

• Please follow the steps listed below to improve the FPS on your Intel Graphics adapter:

• Increase the amount of RAM - by increasing the shared memory under system properties > Advanced > Performance settings > Advanced > Change Virtual memory > use the recommended file size for paging. 

  • Make sure the graphics card is not in power saving mode - If you are after the maximum performance of your Intel HD Graphics, make sure you have turned off all of its power saving features. That is why in order to achieve maximum performance you have to make sure that your Windows power plan is not on Power Saver, you can use the Balanced or the High-Performance power plan. You can also click the Intel HD Graphics driver tray icon (it should be near the clock in the taskbar), select Graphics Properties, then click the Power tab and select Maximum Performance. 
     
    Please, note that although this tip will certainly improve your Intel HD Graphics' performance it will also increase the power it draws, as well as the heat it generates under heavy load (which is the case for games). Caution is advised, especially if you are on a laptop that experiences temperature problems. 

  • Set the 3D preference of Intel HD Graphics to "Performance" - This trick will help you improve the frame rate in games. To apply it click the Intel HD Graphics driver tray icon, select Graphics Properties, then click the 3D tab and move the slider to Performance. In this way, you sacrifice a bit of image quality for improved 3D performance, which should lead to a few more frames per second (FPS) 

Hope this helps! Keep me posted for further assistance.
