I just got an EVGA GTX 550 Ti, and installed it in my new computer build. When it is connected to a standard monitor via DVI out, everything appears fine. However, when connected to my HDTV (my intended primary monitor) the computer will power on for about one minute, and reboot, and repeat. I do not see the BIOS screen on this configuration, however the HDTV does detect an input. When I disconnect the HDTV and connect it to the standard monitor, wait until windows is loaded, and then disconnect the standard monitor and replace the HDTV, video is displayed and everything seems fine - that is, until I try to power on with the video card connected with the HDTV, in which case it just reboots, as described above. It should be noted that no problems with either display occurred prior to the installation of the video card. I've already tried disconnecting all other devices - no joy there either. So what the heck is going on here? If it might help, the box the video card came in was all banged up, and some of the pins on the back of the circuit board had even punctured the bag it came in.
Thanks for the help, it is much appreciated!

Yes, I had this issue before and after installing drivers from the Nvidia website. I could not see many of the caps because of the plastic bezel on the face of the card, but all I could see looked fine. I tried the driver sweeper, but I didn't see anything other than nvidia drivers.
By the way, I've done some testing on the vid card with the standard monitor (playing games, etc) and everything seems fine... is it possible that it is the TV?
thanks for all your replies. Unfortunately, none were to any avail; I was not able to find a manual for the TV, so I was not able to confirm that it was a TV issue, nor do I believe it to be a driver issue. Ultimately, I ended purchasing a different, smaller, TV, on which the graphics card works fine.
