Nvidia Gt540m card not recognized anymore in Windows 7

Question

Hi there,

?

I recently successfully installed Mavericks 10.9.2 on my samsung rf711 laptop.

It took me a while to get the intel hd 3000 working, but all is running smooth now.

?

There is only one problem:?

?

When i boot in Windows 7 it doesn't recognize my Nvidia GT540m video card!

It's not in the device manager anymore.

?

It only showed up when i completely broke my hackintosh partition due to a kernel panic.

?

How do i get my Nvidia card back so i can use it in windows again?

?

Thanks in advance for any help!

I can't reinstall my drivers because nvidia software requires the detection of a compatible card.

In OSX it does detect my card but without any other information except for the seller id which does know it's a nvidia but says 'no kexts loaded'

I discovered that when I reset the cmos by removing the battery for more than 10 minutes it does recognise it when I boot directly into windows. But after a mac boot it disappeared again...

Okay i removed all nvidia kexts in OS X, so mavericks doesn't detect it anymore.

But it is still not the solution for my problem...

When i reset Bios, restore windows and reset CMOS i get it back in the device manager.

But after each OS X boot it disappears again.

For now in device manager under video cards it only detects my intel HD 3000 , and not both the 3000 and the gt540m
