Question What is wrong with my laptop?

[Rochah]

So, my dad bought me a dell inspiron 3585, it has a ryzen 3 2200u and Vega 3 graphics with 8gb of ram and 120gb nvme. But i have this problem that suddendly it starts to overheat getting at 105 degree even if it´s on idle, when that happens, it gets buggy and even the connected earphones sound really terrible. Checking the task manager it does not get above 70% of usage

Sounds like a heat problem and consequent throttling.

See that your cooling airways are clear.
Check that your cpu cooling fan is operating.

You may need to contact dell support for a rma.
Possibly the cpu cooler is loose or not pasted well.

As an interim solution, limit the cpu% in windows power management from 100% to something less.
