No video or Black Screen when windows loads<ATI 1900XT

everything works fine untill the the windows loads the ATI driver. my 2025wm SonicView goes black and says no signal. When i use safe mode it works fine or when i enable VGA mode too. I used driver cleaner and reinstalled ATI 6.9 drivers. I also installed viewsoince drivers too. But nothing working. I formated windows and installed it again with no luck. I tried different tricks such as disconnect the screen cable during boot and then hook it when windows loads with no luck either. Now, the only way the 2025wm works if i use the older analog cable but as soon as i switch cables and use the native digital cable the problem appears again. I should also mention too that the 2025wm worked before on digital but i dont know what happened to it now. I also changed the refresh rate and forced different values but nothing happened. Please help and thanks for ur input!

This Win7 Black screen seems to be a common problem. I have tried windows 7 on 2 laptops, one with ATI Mobility x600 and one with ATI Mobility X700.
On both, Win7 works fine with the VGASAVE graphics driver in Safe mode, but as soon as the ATI drivers are used, the laptops internal screen turns black. However, an external XGA screen, using an analog cable, works just fine. The Win7 ATI drivers just wont recognise the laptops internal digital flat planel.
Is this Microsoft's fault or ATI?
I had similar problems under Vista, but solved that by using some pre-release Vista RC2 drivers. These dont work on Win7 though, so I've switched to Ubuntu Linux.
