Geforce 7950Gx2 choose GPU

[KiiWeee]

Hi,
I have some trouble with my graphics card while installing windows 7.
My card is a Geforce 7950Gx2 and it reecently ''split up'' into a 7900GTX 7950Gx2. But it does work, and i read somewhere that i need to send it in for it to get fixed but f that i'll rather buy a new pc. And now to my problem, when the finishing touch of the installation is about to happen (enter user name and password etc) the screen goes black, no cursor, no nothing. Pure black. i friend told me that i could boot in safemode and enter compmgmt.msc thought the cmd and disable the 7900GTX gpu so that i run 7950Gx2. but since my pc is obviously running on the 7900GTX i can't do that. So, i ask,

How do i make the pc use the other GPU, the 7950Gx2???? This is a single card but nVidia built it out of two older cards (7900GTX)

Does it boot up and show display in safe mode?

Damn u guys are dast
In safemode it boots the installation but shows that it cannot continue in safemode, but i can access cmd, Shift + F10

I have no idea how, it just instead of showing two 7950Gx2's in dev ice manager it shows one 7950Gx2 and one 7900GTX

I have allso a dualbooted XP on my second HDD so i can access windows xp atleast. Allso i tried to install window xp instead of 7 and it all went good, but i was not able to install nvidia drivers inside windows,

Can you install them in safe mode at least?

All your hardware supports win 7? If XP works looks like you might have driver issues.

monsta: i don't know, i removed the fresh xp installation to try 7 again :/

rolli:Yes, that's what i believe too. I installed the new drivers i had on the xp (downloaded w7 drivers) and installed through compmgmt.msc while in safemode install.
