Can't install Nvidia driver,it says"it is not compatible with this version of windows".Onboard IntelHD graphics is Disabled.So googled it and decided to download update.My current OS is Windows 10 x64.But the intial download took more than 5 hrs! and even after that it again got back to 1%!!!The big problem is I have lost the DVD,while shifting to new house.Please guys help me,it would be foolish to purchase a new one...So please provide me alternatives..
