Several second freezes… Is my GPU dying or is it something else?

So i’ve downloaded the latest AMD driver for AMD RX 460(Adrenalin 19.12.2.) and since then I’ve noticed several second long freezes in games like League of Legends and Heroes of Might and Magic V. CS:GO has no problems whatsoever.
I’ve tried downgrading the driver and updating it again since downgrading didn’t help either.
Could my GPU be dying?
When i stress-test my GPU I see no freezes in FurMark.
