Hi guys

I have just received a Gainward GTX670 2gb card as a nice upgrade for a windows 7 64 bit machine which was happily running an Asus EAH 6850 1gb card until now.

I've had all manner of hassle getting it working properly, firstly with the OS getting corrupted due to the drivers not removing/installing properly when removing the old stuff and adding the latest 3.20 drivers from nvidia.

The new card functions now in the sense that I have output from it, and the PC knows it has this card installed etc. But there are problems:

I cannot refresh windows user experience.
GeForce experience software has a 'no entry' sign against the icon representing my card, but ticks against the rest of my system.
In device manager the card has a yellow exclamation mark, but when searching for an updated driver states that it has determined the software is up to date.
GeForce experience states that an update is available, but has no link to this, only a button to search for updates, which the use of results in the 'update is available' text showing again!

What is the best way to ensure my system is devoid of add on graphics drivers so it gets a clean sweep with just the default OS drivers to give a basic display? That way I know I can start from scratch.

Or should I just try an earlier version of the drivers perhaps?

Is there a way to determine if the card has a fault, or is this likely just a driver thing?

Appreciate the advice as I've spent the evening trying to get this done and am not making progress other than rescuing the OS after the initial problems!

Cheers :)

I would first try uninstalling the current graphic driver and re-boot. See if Win7 loads its generic driver normally. Then run CCleaner and do the Clean and Registry both. http://www.piriform.com/ccleaner You may need to run it more than once if your system is pretty messed up.

Then download and install Driver Sweeper: http://www.techspot.com/downloads/4266-driver-sweeper.html
Run DS from safe mode (tap F8 at boot) and have it remove any AMD, ATI, and Nvidia graphic driver remnants it finds. Re-boot and install the latest driver for your card: http://www.geforce.com/drivers
