I've had my GTX 470 8 months now works fine but last week when i booted up n i tried play black ops i got artefacts so I restarted n the driver keeps crashing repeatedly uptill i get the blue screen with artefacts on it. i removed the driver and tried older versions as well as newer beta drivers and still nothing. i tried the card in another computer and it does the same, the driver crashes as soon as ur into windows but the card works fine with no driver installed i coudl browse the net and even play solitare but as soon as the driver is installed it keeps crashing as soon as windows boots up. if anyone ever experienced this or know a solution plz let me know
