Hello community, my friend just bought a gtx 770. He doesn't have an account here so i thought id ask for him. Everytime he reboots his PC, he gets alot of lag in games and he has to reinstall the drivers. After reinstalling he can play normally. But when he reboots it starts to lag. He erased his old nvidia drivers completely before installing the new ones. I hope you can find a solution! Thank you!
