GPU Usage drop all of a sudden in Laptop, asking for solutions

[cobainnn]

Hello, I have a gaming laptop from HP Omen 15 series, with:

- Intel I7-7700 2.80 GHz
- Nvidia GeForce GTX 1060 with Max-Q Design

I have a constant FPS drop in any game that require quite strong system requirements such as; HITMAN 3 (also 1 and 2), Dark Souls, Elden Ring, DayZ and even Fall Guys after some time.
I have already discussed this with several Technical departments of certain games in case it might've solved quickly but their advices:

- Doing a clean boot and running several commands with the prompt such as "-sfc scannow"
- Updating the driver from it's official site or simply re-installing the driver with DDU (Display Driver Uninstaller)
- Initiating the MemTest86 (i won't be doing this until something serious had been detected)
- Scanning with an Antivirus and try it again with using EVERY single IObit application (that was actually my dad's advice)

Didn't work either.

I'm suspicious of my fans being dusty enough for this Laptop (again, because I had came here for the same reasons before), due to stopping my routine monthly fan cleaning like for a year. But i won't be doing anything until i receive a good advice or solution. Additionally, below are the tests from the GPU-Z and lined when Laptop is in default, in HITMAN 3 and DayZ orderly. All of them are tested for straight 30 minutes, if needed, i can also give a glimpse of how it seems because i also have several videos uploaded on YouTube.

Thank you all for your responses already.

Temperature throttling ? 91C is very high for a Pascal GPU.

Did you proper re-assemble the laptop after you took it apart?

Since it's an older laptop, clean-out the dust bunnies from inside and the airvents.

Are all the fans spinning correctly?

Otherwise you could try a TIM repaste / thermal pads replace.

Firstly yes, i don't have any misplaced element on the laptop fortunately.
One of the fans had problems like 4 months ago which was because one of their wings were broken and had to buy the same model, works perfectly now.
Other than that, i can try re-applying thermal paste and cleaning the fans if there are no other possibilities i should know.

Most of the games i play here exceed my overall systems although the laptop was running them perfectly well until this month, not sure if it's high or not
