Razer Blade LOW FPS

[Rav Rommel]

I had my razer blade for about 3 yrs not at first my maximum fps was about 120 as for as i can remember not the fps is now ranging from 15-30 just from playing Dota 2 . What could be the problem? could i still fix this? or is its just because its old?
I tried refomatting the laptop , disk defragment and high performance

RAM:8GB
PROCESSOR: INTEL i7-4702HQ 2.20Hz

Thank you !

Do you know the gpu of it? Is it dedicated (gtx or Radeon rx series) or integrated (intel or amd)
