Fallout new vegas crash with ASUS EAH6850

I have an i5 3.2GHZ computer with windows 7 64bit installed. 4GB RAM, dual monitors connected to an ASUS EAH6850 video card.

I recently purchased Fallout: new Vegas which installed correctly. But when i start the game it successfully opens the main menu, but when i try to actually play it crashes back to windows, without providing any crash details.

I called bethesda softworks and the problem seemed to be my Video card, which is unsupported by the game. I updated my drivers and my card is now recognized as a ATI Radeon. And finally the game works! i can play without it crashing.

but every time i start my computer the next day, and start the game again, it crashes in the same manner it used to before i installed the latest drivers!?! And when i reinstall the same drivers again (the latest drivers which i just updated to) the game runs again.

does anyone know why i have to reinstall the same drivers everytime i reboot in order to play Fallout? And more importantly, does anyone have a solution?

Solution 1:

What I would suggest do is download Driver Sweeper. Uninstall all your video card drivers, restart into safe mode. Run Driver Sweeper, to remove everything related to ATI drivers. Restart back to normal mode, then reinstall the drivers. If I had to take a guess I think it's your video card drivers that keep reverting back to the old ones on restart. By reinstalling it forces the new drivers to be used.

The other option I can suggest is when the drivers are unpacked and placed in a temp file location. To find the .inf file, copy them to another location and before you play force load those drivers.
