Fail to install my graphics card

hello, a game freak is here. i love playing games when i am free. so i recently bought a new graphics card for my computer. i attached in graphics slot then install the disc which is given with the graphics card. but i think i could not install it properly. when i clicked Nvidia geforce 8800 GT properties i found this error.
windows has stopped this device because it has reported problems.(code 43)
click 'check for solutions' to send data about this device to Microsoft and to see if there is a solution available.
now what can i do?? i bought it new. is this hardware problem or my computers problem. help me to solve.
