I purchased my mother a Gateway computer and decided to tweak the graphics a little , so I bought an Nvidia GTX 650 TI video card I installed the card and could not get the monitor to come on at all. I did some research and found out that this card requires a minimum PSU of 450 so I bought and installed a 550 Modular PSU with the necessary 6 pin power connector for the GTX 650TI. The monitor still goes to sleep and the computer is not recognizing the Card any Ideas or suggestions would be appreciated..
