Usually I find that if something isn't DOA and it breaks like a year down the track, it's always an excuse to open it up and try and fix it, if I can't then it's always an excuse to buy something new ;P that's my take anyways 
I had no idea how I could fix it.
It was weird as. When I installed the 465, it would boot into windows fine without drivers. But if I installed drivers, sometimes it crashes on the splash screen, sometimes on the boot screen, sometimes after it loaded. At that point, I swore that it would be my last green card haha. The frustration of failing hardware is quite a thing.
But yeah, $15 postage later it came back working again.
Bought it from MSY on clearance, go figure. It was also recognised as a Twin Frozr card (an MSI card btw) but it had the stock cooler. I'd burn down MSY if I could.
