ATI Driver Issues!

Hi,

I've been experiencing a few issues lately with the last few releases of the catalyst drivers.

I'm running a Sapphire 4850 and 64 bit Windows Vista.

Everything is fine until it boots into windows. I can see the BIOS screens, RAID screen etc but when it gets to the green loading bar before going onto the desktop the screen goes into standby and displays 'No Signal'. The PC continues to boot into windows without any problems. I can log on through LogMeIn and everything works as expected...bar the display!

If I boot into Safe Mode everything is fine and if I uninstall the catalyst drivers and run driver sweeper it then works fine.

I have tried catalyst versions 9.1 through to 9.5 but all do the same thing. 9.2 used to work but has now stopped.

Has anybody suffered the same issues or know a resolution to this?

Many thanks

It's to do with Vista setting the incorrect refresh rate. Normally it can be resolved by using DVI if you connect via VGA and visa versa.

Like yours has ;)

Ok, so is there a fix for this? I don't want to be connecting via VGA as it doesn't look to good! I get a kind of shadowing around icons etc.
 
Once you get it fix try in future not to DriverSweep the ATI drivers.

I very much doubt that ATI DriverSweep the drivers when testing. ATI are aware of what gets left behind from a normal ATI uninstall.

The only time besides the one driver set with the 8GB ram bug that i have problems with was when i driversweep the drivers.

I don't even uninstall now, i just install over the top since 8.12 & have had no issues.

Yeh I usually just install over the top and have never had any problems since 9.4 was released.

I was only using driver sweeper to remove everything as I was installing older drivers to see if they worked!
 
Have you tried using the F8 menu when loading Windows, and choosing VGA mode? This should lower all your settings to very basic. Change to <insert resolution> here, and 60Hz which is fine for all monitors.

As mentioned above your issue is usually down to incorrect monitor frequency listings, which the ATI drivers read on first loadup via your DVI connection, set themselves to and eh walla, your screen can't show the settings.
Worst comes to worst, uninstall your drivers in safe mode, then reload windows with default vga drivers, install and older set and then upgrade without the driver/settings wipe in between.

I've tried the VGA mode and it does the same thing! I've also tried installing older drivers and have always upgraded without uninstalling first in the past.

Go to the DVI control and try to change the alternate DVI operational mode or reduce DVI freq. on high res displays.
