Typically, the model number for your video/graphics display card will be located along the top edge of the card. It will resemble either "CT-xxxx" or "GB-xxxx" (x represents four numbers).
If you do not see the model number along the top edge of the card, it should be located above the heatsink on the component side of the card.
Note: The CT-xxxx model number will be printed on the board itself, not on a chip. (There may be CT-xxxx numbers on some of the chips, but those are not the card's model number).
If your model number is one of the following, please also include the serial number of the card. This serial number will be represented by "T-xxxxxxxxxxxxx" and should be located on the FCC sticker on the back of the card.
I already knew this info. I just didn't want to open the case of the PC...Anyway thanks for the try
