My system installed he Windows 7 SP1 a week or so ago - immediately had a problem: my ATI 9600 graphics card stopped working with the upgraded driver
giving the error message: Windows cannot load the device driver for this hardware. The driver may be corrupted or missing (code 39). The legacy drivers
from AMD/AT also did not work - so I am currently stuck with MS standard VGA driver and oval shaped circles at a resolution well below thy native resolution of my monitor. Feedback from MS is that the card is not supported (legacy), however, their Windows 7 hardware compatibility webpage shows the card to be compatible (at least the original version of Windows 7 was)
I had thought of buying a new graphics card until I discovered today the neither my DVD ROM (Samsung) or DVD RW (LG) drives are working, both also showing the same error message as my graphics card showed. As Windows describes both the ROM and RW drive as 'generic', I wonder whether the upgrade to Windows 7 SP1 has caused a more fundamental problem. As with the graphics card, updating with drivers from the manufactures websites has not helped.
Has anybody else experienced similar problems with the installation of Windows 7 SP1 or know what how I can solve these three problems - unfortunately, I can't use restore as the only versions available are post SP1?
