Looks like a video card problem. Make sure the vid card is seated correctly. Also, if you have a really new vid card, I know some require a 4 pin power connecter actually on the card itself because the monsters need so much juice to run. If those don't work, you may have discharged some static electricity when you installec the power supply and fried your vid card

Good luck
