Wow, what a coincidence, my friend has exactly the same card, manufacturer and all (btw, a giant card, its about the size of a two liter soda bottle) anyways, I built his computer almost a year ago, but its never worked quite right, and recently (last month or so) its been freezing up his computer, so traded him to see if it'd work in my computer (i have a 9600GTX) well I got as bsod (with win7) turns out its the same issue, but with vista and win7 there is a built in freeze timer that will crash and shut down your computer if the gfx card freezes for too long. After pulling my hair out and searching for days I find there is no real solution that will work (a couple of solutions work for some people) for what is called the nvlmkm.sys error. look it up a lot of people have it, you might want to read what it does but yeah, we just rma'd the card about 3 days ago, so you talking about this card on here is kinda ironic.
