Hi guys.

I re-installed Windows Vista on my desktop, re-installed WoW but then when i try to play it says: "Failed to find a suitable display device. Exiting program." And i have no idea what to do, like... I went to search, typed "dxdiag" and then i found out under the screen thingy it just said n/a, so im guessing i dont have a display device atm, but then i tried downloading NVIDIA GeForce 430, which was the 1 the computer had before i re-installed Windows, but everytime it says it dosent work with my version of Windows or something like that, And now im just blank... No ideas, so if someone got the answer, pls reply, cause this is just getting annoying now :(

Are you 100% sure it was a 430?

What is your machines make/model?

Can you try this driver:
