Graphics card not detected

I recently installed a 32bit OS on a 64bit OS laptop. But the problem is it doesn't detect any video card at all. even the integrated one. (Intel Graphics HD family)

So I reformatted my laptop to factory settings,It worked and it's back to 64bit but my only problem is it isn't detecting the dedicated graphics card. (geforce gt 520m)

When I try to install drivers from nvidia the installer only says "this graphics driver could not find compatible graphics software" and tried looking at device manager and the graphics card is not there.

Does anyone know a solution? Thank you in advance!

Systems specs, btw.
Intel Core b960 processor (2.2ghz)
GeForce GT 520m
2gb ram

Oh, and my Laptop is an Acer 4752ZG. Only bought this year.
