what should i do to improve gaming performance on my laptop?

[Nikhil_2097]

My processor is Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz (4 CPUs), ~2.4GHz. Operating System: Windows 8.1 Pro N 64-bit (6.3, Build 9600) (9600.winblue_r4.141028-1500) . Ram 8GB (expandable upto 16GB) . Model name HP 348 G3 Notebook PC. Even when Im playing counter-strike 1.6, sometimes fps drops to 30 fps and sometimes it works at 100 fps. its really frustrating when fps drops to 30. i really hope that i'll get help here.
