For me three years is about the time I consider doing two major service things to laptops.
1. Replace the CMOS battery. One thing you might consider doing right now is to reset all the CMOS variables to their default values. If a battery is low the values can change on their own and create strange problems that go away when the default values are reloaded – until – the machine is turned off again (and perhaps left for a time) so the battery voltage goes low and the bits slip again. Anymore I consider replacing the battery every other year.
2. Clean and/or replace the cpu/gpu fan and heat-sink assembly. The accumulation of gunk in these assemblies (often combined in a laptop) is dependent upon how much use the machine gets and where it is used. Blowing air through the assemblies may or may not be good enough. Local changes in air temperature, humidity, and altitude can make quite a difference in how fast heat is removed from the active components. As well sometimes the heat sink compounds degrade and/or mechanical issues change the heat-sink to cpu/gpu fit.
fwiw

Firstly, GPUs are not suddenly start eating CPU one day. System has
been running fine for 3 years and months on exactly same setup.
Secondly, if you look into this screenshot[1] I have just booted ON
the laptop and it was already running at 84C. The only thing that was
started was Chrome newtab. You see load is way to high but none of the
processes are taking up too much resources.
