I've tried installing the drivers on the ASUS cd, the latest stable (13.9?) and the latest beta (13.11beta9.5?). All appear to install, but the card is never detected correctly and I'm still on the basic VGA driver. I've tried installing manually (run the msi files in the display driver directory), but Vista refuses to use the newer drivers. I also tried forcing it to use the 13.4 driver for the 7800 series. It worked, but the screen was scaled oddly and windows thought that there were like 6 displays attached. Not quite good enough. I've also tried using
pnputil -i -a C:\AMD\path\to\driver\*.inf
to install the win7 drivers directly. I then tried to update the driver manually from the list of installed drivers, but the R9 200 series still isn't on the list. I haven't tried post reboot, however. I'm starting to suspect a bad card, but I don't want to saddle newegg with a return over a driver problem.
