i just had "issues" with a new upgrade to a 460 GTX and it may not help you out but this is how mine was resolved:
Quote:
ok, final update because im pretty sure its fixed now
after "JrRacinFan" suggested the older drivers i tried the oldest i could get to work which was the 261.01 that was on the disk that came with the card then i reinstalled directX 9.0c (for about the fifth time) but that didnt fix it so i realised what i did not do before was use the video card disk to download directX 10 & 11 (since directX 11 comes with win7 i figure there was no point) then i updated it to the latest 266.58 driver from Nvidia website.
something in this combination did the trick because now it works fine AND things seam to be running faster so it was possably a DirectX issue but i think it was also missing some Nvidia files too so i guess the Nvidia download was only meant as an upgrade and only included the display driver and maybe there were some other "needed" files that i must have only gotten from my disk.
i'm just so used to tossing the disk aside and going straight to Nvidia because all the times before this i never needed anything besides the download they offered and we all know the disks that come with cards are never up to date.
the changes i noticed to my computer files was that before when it didnt work all i had was just one Nvidia folder in the main C drive directory called "NVIDIA"
now that it does work i still have the folder in the main C drive directory called "NVIDIA"
but now i also see 2 more Nvidia folders that were not there before, one is in the "Programs Files (x86)" and is named "NVIDIA Corporation" and the other is in "Programs Files" and is also named "NVIDIA Corporation"
thank you to everyone for all the help and advice

bottom line of what you should do:
install the CD driver package that comes with the card and only "then" should you upgrade your drivers, dont just go straight to the latest driver download. (which is what i always used to do and never had any issues until now)
next install ALL versions of DirectX 9.0c, DirectX 10, and DirectX 11 yourself and dont depend on whats supplied in Win7. (i installed DirectX 9.0c and the driver CD with the card had DirectX 10 and DirectX 11 on it so i installed them from the disk).
take note of how i had files that werent there before and see if you have those files or if you are missing them as well.
and finally its basic info but easy to forget, reboot after you finish before deciding if it works or not
