1 week ago,
my cpu began to overheat. I reinstalled the cooling and everything was fine. But then, pc started to get weird microfreeze really often.
In games and on the desktop, nothing was really smooth too.
In games, I get really high framerate but nothing feel smooth and I get those glitches. Like my games are in some sort of ''desync'', feels like I have lags from High ping, but my connection is fine.
Yesterday, I made a full reset of the pc.
Launched csgo, still lagging. But one micro freeze every 1 min. I was annoyed with the performance, So I played with the cpu power consuption settings,
I enabled in the registre some Settings for Core Parking. I went back into csgo. It was worst than ever. Glitching 100% of the time, stuttering, freezing for 2 seconds. I disabled the core parking setting. Still getting this insane lag.
My pc specs:
i7 7700k
1080ti rog
16 gb of ram
New ssd from september.

What should I do next?
