ATI drivers causing System Freeze at Windows Logo

Hey everyone.

I am stumped. I have:

Asus Sabertooth Z77
i5 3570k
2x 8gb Gskill Ripjaws X DDR3-1866
Gigabyte 620w PSU
Sapphire 4850X2 2gb
Cheap Wifi USB dongle which I use to connect to my Android hotspot
Newly installed Win 7 x86

Windows loads fine without a VGA Card, using the onboard HD4000.

Windows loads fine into safe mode using discrete VGA card.

Windows loads fine in normal mode the first time I install the VGA card. Windows then installs drivers for the card, which I immediately uninstalled and replaced with catalyst 13.1

Windows now will not load past the windows logo. It locks up every time. Just as the speakers click and the logon page should show. I have also tried Sapphire's 12.6 drivers with the same result.

Anyone had an issue like this? All the individual components have been tested and working, except the m/b itself. It is clearly an issue with drivers, dx11, or hardware compatibility. Will do a format and reload tomorrow and see what happens. Any other ideas?
 
Hi Joker. I see you have been MIA for a while. Hope you are well. It is a Gigabyte Superb 720. 610w (sorry) , Max 720w.

Cronus, have tried catalyst 12.6 which I have used successfully with Win 7 32 bit on my old LGA775 board.
 
[SOLVED] No. Had the same freeze on x64, so tried x86 but the problem persisted.

Just did a format and reload of Win 7 x64. Installed every driver one by one and found it to be the Intel 4000HD drivers which were conflicting with my Catalyst drivers. The motherboard is supposed to automatically disable the onboard VGA when you plug in a Pci-Ex device, but it seems to get confused as to which display to use when you boot up, causing it to freeze at the Windows logo just before entering Windows.

So I booted to safe mode and disabled Intel 4000 in the device manager and it solved the problem immediately when I rebooted.

My only question now is: Why should I have to disable my iGPU? Isn't it supposed to assist my VGA Card? Perhaps intel will resolve this with a later driver release.

Thanks for the help all.

It provides no assistance, the only place integrated can help really in your case, is if the integrated could handle PhysX processing, then its possible to have that happen on the separate device.

If your not using integrated try disabling it in the BIOS, anything that's on uses some (even if just a tiny amount) of resources and I think there is still a system memory map created by the device being active meaning it's reserved some of your system ram to output nothing.
