Pc games have started to lag and make crackling sounds

1

My pc worked fine a few days ago but suddenly my pc games have started to lag a bit and make popping crackling sounds especially when the videos and cutscenes play.Google chrome 1080p60 videos also lag and make the same noises as the games but every other browser works fine in 1080p60 videos (microsoft edge, firefox).I've updated to the latest nvidia drivers & sound drivers,downgraded to beta drivers,temp inside is also fine,I've dusted everything & re positioned the ram sticks,defragmented drives and I haven't overclocked my cpu.The games and videos still work but they're now choppy and I can't find where the problem is coming from.

Try downgrading to previous Windows version, if you have the time. My CS:GO got laggy and the only significant thing happened was a big Windows Update to version 14393. – pedro – 2016-11-06T22:13:07.730
