if you are running w7 and all the drivers installed your dragon is working just the graphic driver is playing up and its hanging down load 257.21 graphic driver on page one on this form and see if that sorts your problem then proceed to the next step below w10 will keep all your drivers and it should work like clockwork if you have a problem getting updates when your running w10 download this tool and it should fix it Right click your desktop, select Nvidia Control panel. Under 3D Settings\Manage 3D Settings scroll down to Power Management Mode and set it to Prefer Maximum Performance. Now in the next tab over, Program Settings, make sure that each program is also set the same (either as 'Use Global Setting' or 'Prefer Maximum Performance'). If you don't see a program listed, you will have to add it and make sure that it too is set to 'Use Global Setting' or 'Prefer Maximum Performance'. Though it is better to set to Prefer Maximum Performance in case Windows updates the driver in another build or update. Note though, that setting this mode in Windows 10 results in increased fan RPMS. Similar to the fan noise you would hear if you were in dual screen output mode. And temps will rise to the low 50's or so. ok 2.0 send me this and it works What I've done is to change the Nvidia settings in Win7 before doing an upgrade install to win 10. Even though the settings might be reset to default adaptive after WIN10 installs its own default Nvidia driver, it gives plenty of time to change them to prefer max performance without incurring a crash. One other tip before doing the upgrade install is to reduce the number of background programs you have running, especially any 3rd party anti-virus programs. Also anything the runs in the tray that is third party.
