Performance way less than should be

[Praxfrl]

So recently i built a pc with an asus 1080ti poseidon and r5 3600, 16gb of ram and 750w of power and im really not sure what's happening, at first it was fine i could play games but after a week or less it all went downhill so fast, minecraft completely crashed and sent me an error about old drivers or a recording software interrupting the pc, but i rolled back my drivers, reinstalled new ones, tried all of that, deleted any recording software or benchmarking that has overlay yet nothing changed, now recently i can play a little again but the fps is horrendous, with my specs im only getting about ~48fps averages and 1% lows of 15-30fps, i only play mc with shaders and minimal graphic settings, on other games too like assassins creed i just crash or get REALLY bad performance, someone help!

check the cpu temperature, if the numbers look normal then open up gpuz and look for any power/temperature throttling in the sensors tab, under PerfCap reason

Check temps in HWinfo64, CPU and GPU hotspot temps
