Ubuntu won't detect my GPU (NVidida 520m 1GB)

[ahmed samir]

Tried that already . . Didn't work. Do you have any more suggestions and Are you sure the problem is becausee of the kernel version ? I installed this kernel because the default kernel that comes with Ubuntu 10.04 was too old for my wireless card so I couldn't connect to the internet by any means. It would be really great if you can tell me a kernel version that would automatically detect both my GPU and my wireless card automatically. 
My GPU : (NVidida 520m 1GB)
My wireless card : Intel Centrino Advanced N 6230
Would definitely appreciate your help.
