i installed windows vista on my pc, and when i boot up computer it says video card cannot be found. i go into device manger and it says: Windows has stopped this device because it has reported problems. (Code 43).
Iv tried reinstalling software, letting windows install video card itself, and downloading vista drivers for it ..installs fine says everything is gud, then i restart computer and nuffin says cannot be found.
video card im trying to get working iz 8600GT ddr3 512MB which shud work on vista. What can be the problem, vista? or my video card iz faulty?

the answer is by heaVen :
maybe ur video card is faulty or can be u are lacking of 1 more driver.
