System not modified

[Marty_uk]

Hi guys

Recentley i had a mail from nvidia stating the new drivers were out for downloading so yeah i went ahead and downloaded them.
Now when the installation is complete i get a message saying "This system has not been modified" since this has happend my Geforce 9800 Gx2 (vista64) has disapered from my display settings,i cant run games at all as it says it failed to find a suitable video card.
Ive spent hours searching online in forums for answers and ive pretty much tried them all Ie.

Changing regional settings
Running driver cleaner
Tried installing in safe mode
Tried running as admin
Used windows update to try install them and no luck
Tried deleting from device managed and refreshing to find drivers still no luck

None of these work at all and now i my restore points have disapeared too so i cant even do that i am totaly baffeld in what to do ive never even attempted a reformat since im not to sure on how to do it.....Any advice would be great thank you
