micro stuttering and fps drops

[etze]

hello guys

last 10 days or so (i think) i've noticed there's some micro stuttering going on

 

i was playing a game the other day (lineage 2) and the screen turned black and i had this message:

"Nvidia display/kernel mode driver has stopped working and recovered succesfully." 

 

stuttering occurs every 20-30 seconds for like half a sec 

also, there's weird things going on when i open new tabs on chrome etc

like this (i added the black bar that covers the bookmarks) :

my chrome was not responding and it was like this for like 20-30 sec until i closed it through task manager

 

also, a couple of minutes ago, i started playing with like 10-20 fps for about a minute and then it came back to normal

 

micro stuttering occurs in all games

 

i have windows 7, msi gtx 970

drivers version 384.76

 

any ideas what's going on?

It does sound like a driver error, try reinstalling with DDU.

If that doesn't work you can always try uninstalling again and dowload an older driver that works better for you
