Display Driver nvlddmkm Stopped Responding, ive come to live with it, but gah its annoying. Options

[Dagger]

im hoping windows 7 fixes this..

running Vista
gigabyte ex38-dq6 MOBO
gigabyte ga9800GTX (runs at 51 degrees all the time)
8GB RAM

ive had the mobo, power supply and ram replaced (under warrenty ).. and i still get this problem :S

i cbf playing any games other then TF2, CS or COD4 as they only cause this error once in a blue moon. (COD4 doing it the most)
but yeah it wont let me play RA3 (only tried once or twice)
do i just get a new graphics card??? updating drivers hasn't helped over the past year .
