Hi, as the topic says, my screen isn't working after I put in a new graphics card. it was a Nvidia Geforce 9500, I put it in the correct slot, PCI or PCIe, and the screen doesn't even DETECT the computer now... the first time, I put it in poorly, the second it went in perfectly...but the screen still didn't work, I have been at this for 2 hours. Any help would be greatly appreciated.
