nVidia GeForce 9800M GT problem D:

Hello there, i've been havin problems for the past 2 days regarding Windows 7 64 bit; first i installed the 32 bit version, as my Alienware m15x came with a Vista Ultimate 32 bit version, but Windows Update on Windows 7 made me get blue screen because of unknown issues, so i thought the 64 bit version of Windows 7 would help me.. but it didnt.

So, i became desperate and managed to find that in Device Manager, my nVidia GeForce 9800M GT driver was with a little yellow attention icon, so i clicked it and it turns out that "Windows has stopped this device because it has reported problems. (Code 43)"

So i was lookin everywhere, on different forums and i couldnt find a solution.. My graphics on Vista were lovely and i could get Aero up and running, but now everything seems laggy graphic-wise.. i went to the Alienware support page (My Hive) but there are very few drivers there and none of them were for my nVidia card... Even on the nVidia website, i let their software scan my computer for Graphic Drivers so i installed the one they recommended, and hoped it would work after the reboot.. but it didnt. Blue screen...

So im helpless, and i come to you guys with hope that you could help me.

Thank you for readin my wall of text and i hope you have an answer for me.

PD (if u need to control my computer [Via TeamViewer software which i trust] u may, because if that's what it takes, im down for it)
Oh and i also posted this on the Drivers forums cuz i didnt knew on which one was more appropriate

I already have the 197.16 driver installed, and no luck...

EDIT: None of the drivers from Dell support or Alienware support apply for my graphics card. ):

News: i tried installing the 197.16 via Device Manager, but it didnt work... should i uninstall my current NVIDIA driver, reboot and reinstall? because i got the 197.16 saved to my desktop..

It still doesnt work, is the only way to fix my pc is going back to Vista?! Please help me!
