Problems after SP1 upgrade to Windows 7 Pro  

My system installed he W7 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 W7 hardware compatibility webpage shows the card to be compatible (at least the original version of W7 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 W7 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 W7 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?

Thanks for the reference - not sure if the steps are still relevant after installing SP1. With the exception of installing the latest drivers in step 1 (they were already installed), when through each step: SFC/SCANNOW reported no errors; System Readiness Tool (W7 for x86) reported no report any integrity violations in either of the log files; Ran FIXIT - identified the three problems (DVD ROM / DVD RW drivers and ATI Radeon 9600 driver, but did not fix anything and simply reported that the device drivers needed to be reinstalled.

I can find no other help on the MS site on what is causing these problems, particularly the DVD ROM and RW devices as the drives for these should be generic.

Does anybody have any other suggestions as I'm kinda irritated that SP1 has effectively crippled a working PC - I could have lived with the graphics card issue, but no DVD drive access makes the PC effectively useless.
