CSGO fps drops while jumping

[Morsher]

What up. My PC specs: 4670k (4.5 ghz; 1.375 volts), gtx760, z87-a mobo.
I have fps drops every time i jump or switch weapon using buttons 1, 2, 3. And sometimes it drops harshly from 250 to 180-160 and bouncing back. It makes my screen shaking.
Also i have CPU Fan Error on the starting windows. I have Corsair H110 Cooler and i've not touched it since it's been installed. Didn't change RPM in mobo settings either.
So if you know what's the problem and how to fix it please help. I'm tired of shaking screen. Can't play like i used to.

could be a sound problem. I would recommend that you verify the game cache( right click on the game in steam library, click properties, local files, verify cache) and update your sound drivers.

well it shouldn't affect your FPS at all, unless it somehow changed your video settings. Are your temps fine? CS:GO  is pretty CPU intensive so if you have a problem with your cpu fan maybe it's getting too hot .

All fine. Im not getting above 73-74 degrees. Although in other source-engine game (Left 4 Dead 2) i don't have this problem. It's only about CS:GO.

It drops from 230 to 120 when i crouch and press 1, 2, 3 or when i jump and pressing several buttons simultaneously.

do you have geforce experience? I know that the share feature built into it can cause some lag if it is enabled. So I would turn it off if you have it on. Other than that I'm not really sure, seems like kind of a weird specific problem. Have you updated graphics driver recently? if you have maybe try to roll back to a previous version and see if it helps.

I hope you're not using HRTF audio. That thing is pretty bad for frames apparently.

I turned it off immediately since update came.

That might be the case. I'll try today after the work and tell you if it fixes the problem. And yeah i'm updating drivers systematically.

[Morsher]

Yeah. That was nvidia geforce experience. Thank you elpiop.
