Not all TV Tuner cards are recognized by Media Center. If the tuner card doesn't have hardware encoding then it may not be a supported card. Also if it's an HD tuner card Media center requires at least one analog tuner card.

I suspect you may have already done this but .... Try re-seating the card again.

Is the video integrated into the motherboard or a separate card? If the video is on a card then try re-seating the video card.

Is the TV tuner a separate card or part of the video card (ATI All-In-Wonder)

Almost worse case scenario:

try resetting the CMOS. If that doesn't work then You may need to get down to necessities and remove any add-in cards (except for video) and disconnect all data and power cables to the HDD, CD-rom,and Floppy drives. Then try booting up with just the motherboard, processor, memory, and video.

It's a common occurance where someone opens the case and reseats or installs cards without ground protection. First, I never unplug the power cord, there's nothing in the PC that can hurt you and by doing so you have just ungrounded the case and the only protection you could have had. The power supply has a case around it the prevents you from getting into any hazardous voltages. I always have a ground strap in my pocket so this likelyhood is not going to be created to start with. With a grounded case, just removing the cover will have eliminated any static charges that can kill anything you touch.

ok i had a ground strap on i also never work on my baby without it.That's hat i don't understand.The t.v tuner card that i had installed in the pc was a rather odish one,but never caused any trouble.
