The symptom you describe is more likely from a faulty card or cable/cable
connection. DVI connections can caused problems. Make sure when you tighten
down the connector you take a turn or turn on each side and then do the same
for the other side otherwise the connector may install crocked if you
tighten one end all the way before you tighten the other end.
The latest Vista drivers are the ones at the NVIDIA Website and are the
162.22 drivers. New NVIDIA drivers always appear at the NVIDIA Website
before MS also starts shipping them with Win Update.
Also you might try just using one 8800 card at a time to make sure they are
both working correctly.
Also if the problem normally happens under high activity you may have an
underrated power supply.\
