New build, GA-A75m-UD2H motherboard
A8-3850 (integrated Radeon HD6550D
8 gb Corsair Vengeance RAM
System boots initially following installation of Windows 7 64-bit on standard VGA drivers.
Install ATI Radeon graphics drivers from CD. System will boot as far as the 'starting windows' screen and then go blank.
System will boot fully in Safe Mode (using standard VGA drivers, of course).
If you uninstall the Radeon HD6550d display adapter from Device Manager in Safe Mode (but do not delete the drivers), system will reboot (again, on standard drivers), auto-detect the HD6550d and reinstall drivers. This install reports as having completed successfully, but the AMD Vision Engine Control Center will not run, reporting that there is no AMD display adapter installed, or that the drivers are out of date or damaged.
Rebooting the system from this state (with the AMD drivers installed and enabled) will result again in the blank screen.
If, in Safe Mode, you uninstall the Radeon adapter AND delete the driver, the system will boot in normal mode, as standard VGA, and apparently function quite happily for as long as you like.
Bottom line: System runs fine if AMD drivers are not used. System will not boot if AMD drivers ARE used.
Same results with a) the driver package included on the CD with the motherboard; b) the newer driver package downloaded from Gigabyte's web site; c) the driver package recomended and downloaded from AMD's website; and d) the driver package that comes from Windows Update.
To stress: there are no errors, no beeps, no BSODs, no core dumps, no logs, nothing. You see the 'starting windows' screen and then blank. After you reboot (manually) the Windows bootloader will report that the system was previously unable to boot and offer to repair the installation. If you say yes, it will think for a few moments and then report that it can't find anything it can fix, and offer to restore. If you say yes here it will then boot up fine, after, of course, the restore has removed the AMD drivers.
If past experience is any guide, I won't hear from Gigabyte's 24-hour tech support response line for at least another 70 hours, and the AMD website appears to offer nothing.
An oddity: Windows will only recognize the HD6650d if the drivers happen to be present on the system. Otherwise a hardware scan shows it only as a standard VGA adapter. A side effect of embedding the GPU on the processor die?
Anybody seen anything similar or can offer any suggestions on where to go next?
Thanks.
