Please someone help, after trying to get nvidia drivers working and having to call nvidia support they made me update to windows 10 version 1607 and said that would fix all my problems and then the drivers would install correctly, well after literally waiting 9 hours for the update to download it installed and i let the computer restart itself to adhere the new update. After booting the computer the next time and everytime after that it freezes, stays at 100% cpu load, lags extremely bad, internet it less than half the speed it used to be and the problems keep coming. So i did a clean install of windows 10 again and the problem still persists. Everywhere i looked people say to roll back to 1511 that i had prior to the update, but when i try to roll back my system doesnt have any previous versions of windows at all, this is is even before i did a clean install again. What do i do??? my pc is literally useless and cant even open up the start menu without freezing.
Clean install, no antivirus, no other programs at all only what comes with windows
