Hi, recently I purchased the above mentioned card. Ever since whenever I play Oblivion, the pc will crash either to desktop or will restart by itself. It does not happen with my old card which was Geforce 5600. I would like to ask if the above mentioned card need to be connected to my power supply. I think that could be the problem but I could not find the source to connect to the power supply if any. I have also updated to the latest drivers. Any help would be greatly appreciated. Thanks and regards.
