a few month ago my old gpu died.
i build a new one (gtx 1060), and everything was working fine. after a about a month my fps in games suddenly dropped and my sounds cracked. i reinstalled my drivers and it worked again. now i have the same problem again, but nothing i try fixes the problem. i even completely reinstalled windows, but it didn't help. the fps drop is around 75% (in gta V, from 80fps to around 18fps) and the sound crackling is now also outside gaming, watching videos and such as well.
i have no idea how to fix it.

extra info:
gpu: gtx 1060 msi gaming X 6g (nvidia 379.20 driver)
cpu: intel i7 930 @2.8ghz (overclocked to 3.7Ghz, liquid cooled)
motherboard: flamingblade gti
ram: 16GB
monitor: 1080p
headset logitech G430 USB connected, logitech gaming software 8.87.116)
windows 10 .

test:
msi comombuster stress test: pc freezes have to restart
intel diagnostic tools: all passes
memtest: pass
prime95: at least 1hour without errors

the fans are not spinning, they only do when temperature go above 50C.
and with gaming i don't get them above 47. but i can turn them on if i wanted.
i also tried stress testing using msi combuster, but my pc completely froze.
i registered if you mean loging in when installing nvidia drivers/geforce.
