Somehow my fps drop a lot while gaming (Every games ) and it just drop for 45-60 seconds and it go back to normal .Some time there is a notification pop ups say'' Display driver stopped responding and has recovered'' . When this notification came up my PC lag and drop fps from 200+ to 30+fps in CSGO.

Reinstall your Nvidia graphics drivers or try Updating it at least, btw check your temperatures while your playing, could also be the problem, but with that notification i would assume its most likely a driver issue
