You can get them from here:

there's also an AMD link, but that's almost impossible to find.
However, for me, i've had this issue from day 1 and no driver since has fixed it... it seems sometimes to be fixed after a fresh install for a couple days, but then crashes again.
I'm not sure if this is a driver issue, a hardware issue, or something inbetween...
