first of all when u install a new window the system needs some time so that wei can rate the system after a using many times wei adjust the system rating
make sure that the card require 2 6pin pcie connector to run it
u have to update bios also for system stability
and what version of nvidia driver are u using on it i prefer 301.42 whql driver for gtx 560 ti
Updated Bios already (Should of included that), The driver I was installing was 301.42 - WHQL which didn't help fix the black screen problem. The card has two 6pin slots so I can only assume it requires two six pins to run at maximum capacity.
