ATI 4850 crashes 64 Bit Pro on startup

[pjfouler]

I did a clean install of 64 Bit Pro and it will start up fine the first time. As soon as it updates the ATI drivers, on restart it will crash as soon as the desktop appears. The card works fine on another system using Win7 RC. If I put a nVidia card into the new system it works fine with no problems what so ever.

Why is the 4850 causing the system to crash?

Thanks

Try updating your chipset drivers.

Install latest video driver from safe mode, using the device manager and pointing specifically to .inf. Reboot to normal mode and see how it goes.

Device manager ---> right click standard vga, update driver software, browse, let me pick, have disk, browse. Now navigate to the .inf and double click on it. Hit ok.
