Windows 7: windows 7 ultimate can't detect nvidia 9600 gt card

Are you rebooting after every failed install?

yah i have i will try it n reply later

not after all but some times...

What I'd do is uninstall the current driver and reboot, let Windows reinstall the driver, then proceed to try and update with the NVIDIA drivers.

yah man but windows itself installs SVGA driver after every restart and while trying to update it says driver is up to date.and if i try to install drivers from nvidia site it says "not compatible with current hardware".

i checked the motherboard now and everything is okay . can you tell me why it is not being detedted....
if windows cant detect hardware how can i install drivers???
are there any methods to detect connected hardwares?

waiting

PSU is rather crap - have you connected the 6 pin connector properly?

Did you try what I suggested using drivers & a modded inf from laptopvideo2go as well?
