Does anyone have any idea what I get this image in my Mac Pro 4.1 + ATI 48xx graphic card?

It happens every 1 of 3 times I boot up in windows.
If I can enter my session and close the session I get the image correct next time in the session's login screen.


Thankyou
Gus

Are they using the same resolution? Without knowing what you're using for running windows, it is hard to just guess. There could also be a hardware fault, but that would take more testing and I dont see that as being what is wrong, provided you are having no issues in OSX.

Specs:

BOOT CAMP 3.2
WINDOWS 7 64 BITS
ATI RADEON HD 4800 SERIES
AMD RADEON CATALYST CONTROL CENTER 2011.0524.2352.41027

Never had any issue under Mac OS X.

Are they using the same resolution?
It's not related to resolution, I can login (with luck if I can put my cursor on my login icon) and I got the same distorted image.

Thankyou

I installed the last
Catalyst Software Suite 86.4 MB 11.6 6/15/2011
drivers.

I got the same problem, first with apple bootcamp drivers and now with AMD "official" drivers.

But "the problem" is that only happens 1 of everery 3 o 4 times I boot with windows/bootcamp.

Download the correct driver and try that. You will need to be in Windows to do that, and install.

I have done that.

BTW harryb2448 I have the same machine like you ant the same SSD.

Have you had any probem with OWC SSD?
Sometimes it doesn't wake up from standby and I have to reset the Mac Pro, (in Mac OS X)
