I just added new memory and a new graphics card to my dell dimension 3000 desktop computer. when i added the new memory the computer was fine, but when i put the new graphics card in and started it up the fan started going really loud. (sorry not very technical). Is there any way to make the fan quiet down? the new card I put in did not have a fan attached to it. The card is a PNY GeForce 5200 PCI card.
