Hi, I have 2 computers and whenever I put the graphics card (only one i have) into either of them, they will not start. They start fine on their own without the graphics card. Also i recently got some money and would like to buy a new part to raid but I don't have much and i'm not sure what i need to buy and i wouldn't want to order the wrong part. The card I have is a GeForce GT 120, and the computer with the largest Power supply is 450w. Thanks in advance!
Edit: Whenever i try to start it up on the computer it came in, the fan makes a "whirring" noise for about a second and then stops. Doesn't light up at all.
