Weird freezes playing CSGO

So sometimes i get these 1 second lags in csgo just randomly and if u play csgo, then you do understand that this is a annoying problem, like if u are spraying at someone then the lag just appears.
I just cleaned my pc from dust so its not that.
Should i check my temps while im playing?
Is there something wrong with my gpu or cpu?

I appreciate all answers!

Hello Tkosj,

Have you tried doing a clean boot and running CS:GO? there could be something running in the background running that is interfering with your gaming? also do you have the latest GPU drivers for your nvidia graphics card? doing a scan with Malwarebytes and checking your temps wouldn't hurt .
