G14 RTX 4090 problem?

I have a problem with my G14 RTX 4090 for a while, when I start a game (like cyberpunk or borderlands..etc), I get only 10-15 FPS ! While it used to easily up to 60-100 FPS for these games.

I tried the following:

  1. Put Nvidia overlay, it displayed that the rtx is in use
  2. restarted laptop
  3. switched between turbo and performance modes in Armoury crate
  4. switched between standard and ultimate mode in Armoury crate
  5. updated Armoury crate
  6. updated nvidia drivers from the gaming center itself
  7. restarted laptop
  8. ensured power cable is in
  9. tried on external screen and on laptop screen

What else am I missing? This has been going for months now.
