[2020] Runescape is crashing my PC?

So as of the past couple of days RS3 has been crashing my computer and puts it to an auto restart of some sort. Its not giving me the blue or black screen of death just shutting my PC down and restarting. I can play any other game with no issues which makes this even weirder. I've tried clearing my cache and deleting and re-downloading the client itself. Am I missing something, was there a recent update that could be causing it? Any help would be greatly appreciated!
