Question High CPU usage frame skipping, crashing 1080ti, 32gb, i7

Apr 1, 2020
I have been having major problems frame skipping and high cpu usage. My build should be more then able to run any game to date, my fps counter (fraps) tells me most games at least run at 70+ fps some going 200+ even though they're clearly running at around 20 - 35 and that's after lowering all graphic settings, the temperatures seem to be fine never going over 45, i dont know what to do, ive also reset windows, ive added an extra case fan, to cool the cpu when running games or google chrome cpu usage sits at 75% - 90% even on low quality games with no background programs running.
My build:
. CPU: Intel i-7 8700 3.20GHz
. Motherboard: ASUS PRIME Z370
. RAM: Corsair Vengeance 32gb ddr4
. GPU: Inno 3D Geforce GTX 1080Ti 11gb
. PSU: Thermaltake 850w
. CPU Liquid cooling: Cooler Master dual fan

Side notes: always takes a while to turn off. Some games and google chrome will make it crash, there is more then enough free disk space. Its kept dust free. Troubleshooting this problem would help so im over sending it to pc repair shops and it still cant run games please help.
