inputlag Razer Cynosa v2 INPUT LAG/LATENCY issues

[eexotm]

In every game, i feel like there is a bit of an input lag and a DELAY when I let go of the key. What I mean by that is let's say I Press the w key and let it go. the character goes front but still keeps going front when I literally let go of the key a second ago.  I have a razer cynosa v2. my pc has other problems like underperforming even though I changed my mobo, gpu, cpu with new ones couple times.  I did another thread about this. people said it could be my ssd. Well I don't have another choice anyway. so keep in mind that I might have a broken ssd too. can ssd cause input lag in devices? I would be happy if someone helped me. thanks
