I think your 9800 GTX running in PCIe x4, when it should be running on PCIe x16. Are you sure you connect the card into the PCIe x16 slot right? Try reseating the card in the slot. Additionally, you have adequate power for the card? Look at the label of the total power and the amount of current your +12 V (s) can provide. The 9800 GTX requires much more power than a 220 GT. Have you connected the required 6 pin PCIe connector of power supply to the card?

Thanks for the help. After referring your post I have connected my graphic card in 16X PCI and after that when I start the computer at that time graphic performance was nice. now all the things are working fine.
