My laptop is Samsung np300e5e (series 3) and has intel graphics and I played a game which worked fine but its speakers were not working so I gave it to a laptop repairer.

When I got the laptop back its speaker was working fine but every game started lagging.

Problem

Whenever I played the game (Inversion) laptop expelled much heat out and laptop fan would start running faster and faster and temperature of air coming out of the laptop was too much but now laptop does't go very hot and the air coming out is also not very hot and fan is also not going fast and the game also lags after being repaired.

What I have tried..

I think this is some hardware related issue , I have tried updating drivers and updating the setup settings (F2 to go in setup when booting) and now I am going to install windows again.

What I want

can someone please help me or guide me what could be that is causing the issue that every game is lagging.I have read much about thermal paste but I don't know if thats the problem.

I'd initially check up on the power setting and make sure you're running in High Performance.

Perhaps it may be worth giving the repair shop a call to get a detailed overview of the work carried out on the machine?

Thermal paste is like glue to make ur processor cold.

Okay first check task manager.and see if ram/cpu usage is high.show detail and find any process that make ur laptop lagging

Second,try update ur windows.and install all ur driver with driver pack solution

If none of them working,return that laptop to that laptop repairer and ask him to be responsible
