[SOLVED] Plz help pc lagging on games

[Binhwin]

Hello, my name is Binh and this is my first post to this website.
Long story short my pc keeps experiencing weird random lag spikes. So I bought my pc used about 7 months back. Spec list will be down below. So first off when I got it I bought GTA v and it ran it beautifully. I recently tried it and it’s laggy for me now. But my bigger weirder problem lies with outer worlds. It’s very weird. So the first time I played outer worlds I streamed it and got some weird lag. The game would experience random short stops for like half a second. Like the game was choppy? So I figured it was the stream. I turned it off and tried it again today w no stream and same exact lag. I switched the settings from very high to just high and got the exact same lag as when I was playing on very high and streaming. I’m very new to pc so any help would be so awesome. I ran a bench mark and these were the results
Here are the results UserBenchmarks: Game 74%, Desk 72%, Work 42%
CPU: Intel Core i5-6600K - 75.5%
GPU: Nvidia GTX 1070 - 79.4%
SSD: Tcsunbow X3 480GB - 91.1%
RAM: Unknown TEAMGROUP-UD4-2400 2x8GB - 79.9%
MBD: MSI Z170A GAMING M5 (MS-7977)

Again if anyone has anything’s I could do please let me know.
Thanks so much for reading!

It’s the Corsair cx750.
I ran some tests yesterday and learned my gpu was running at at 84+ c. I took it out yesterday cleaned a very dusty case and swapped the thermal. Tried game again got same lag, I will say it was a little better though. Gpu temps went way down but the 6600k is still at 100% work load. Is maybe the game just too demanding? Because I thought maybe other stuff is running in the back, and I checked. Nope the game hovers at around 80 usage.
Thanks for reading!

well yeah cpu is made to run at 100% and should do try and optimize your graphics settings how many case fans do you have the more the better larger fans are quieter.

It’s liquid cooled ( Corsair brand forgot exact model) I’m using two vdc brushless Corsair fans inside. I was thinking of mounting another one but it’s hard due to the lack of room in case.
