Unable To Keep Installed 8800 GTX Driver

I installed Windows 7 64 Bit 6 days ago and Im still trying to find a solution to my nvidia drivers. I have a dell xps 1730 with nvidia's 8800 GTX SLI. I have been reading several forums and posts and Ive done just about everything theyve said to do and still no luck.

Here's the scoop, so I have downloaded 186.03_notebook_win7_64bit_international_whql from the nvidia site and 18172_win7x64 from nvision along with the modded inf file. Have installed both as described on both sites.

Ok, this portion happens with the nvidia site driver. It installs just fine the restart where the issues begin. Once it reboots and begins to load Windows 7 it freezes up the goes back to the bios and on to where it asks to do the starup repair thing or start window normal. So Ill hit start normal, same thing will happen. I choose to fix then I proceed to install all over again. Again, reboot same thing, I choose star normal and this time it goes to the screen where you see the cursor and it says welcome then suddenly crashes.

Now for the nvision site driver. Install is same both ways. Restart, goes thru bios now on this driver it hits the Windows 7 and immediately gives BSOD. So I reboot, again same thing. Once more only this time it goes thru and Im able to get into Windows 7 like nothing. Ok great, well not really. No nvidia panel, so I adjust the resolution go into driver manager to check the status and it says that it not working because it needs a restart, ok so I restart. Again BSOD over and over.

After every attempt I have to fall back to a previous restore point and still have had no luck.

Am I getting the wrong drivers? Is there something Im missing? Could it be just a Windows 7 issue?
