Windows 7 video card problem

I'm installing Windows 7 Beta Build 7000 on my computer:

Intel Pentium 4 2.8 Ghz
P4S800 motherboard
Kingston Memory DDR (1 1gb and 1 512mb)
Video Card ATI Radeon X1650 series

My problem is during setup when windows 7 checking video performance, it will hang up there, after forcing it for re-start, it will continue the setup.
But the problem is i can't open any application, it says you have no administrative rights for this applications.

Is the vide card problem preventing the windows to be accessed?

Anyone, please help

Thanks

It is highly unlikely that the video card is producing this problem.

Im not sure but i think your board has an onboard VGA slot on it. (leaset i know the P4s800-MX version does)

take out your video card and plug your monitor direct into the M/Board.

reboot and see if the error still continues. If it does not then you know its the graphics card. Of course being in the beta stages the vast majority of companies will NOT be developing drivers for their products yet for Windows 7. some companies are still getting problems with VISTA.

Hope this helps you
