4850 Problems in Win7 64bit RC

[fsarfino]

Over the weekend I installed Windows 7 64bit RC. Everything went smoothly until I went to update my drivers. After installing ATI Catalyst™ 9.7 Suite for Windows 7 (64 bit). The OS no longer recognizes my card.

Just for the heck of it I even tried to use windows update to update to the 4800 series driver they had and again the OS will no longer recognize my card.

However everything is fine with the driver that was loaded at install. Anyone have some advice for me ?

Here are my system specs

MB-Jetway HA04
CPU-AMD 9850BE
Videocard- Asus EAH4850

Bad driver install maybe? Remove the old driver with driversweeper or something like that and try again.

I seem to recall one of the windows update drivers nuking my display way back with one of the W7 betas. The W7 beta driver ATI had up seemed to work fine for me with RC.

I'm on W7 RTM now and haven't had any issues with dual HD 4850s. Quad monitors & crossfire work fine with 9.7. Even the hydravision grid and the avivo encoder are functional now.

Did you try rebooting into VGA or safe mode, running the cat uninstaller, and re-trying 9.7? Perhaps as was mentioned it was simply a creepy install. Also ensure that it didn't simply swap your display outputs. I've had new driver installs pull that trick b4.

The 9.8's are not on ATI's website. 9.7 is the last version.

9.8's can be found on guru3d's site.

Thanks for the replies !

I pretty sure I figured out what it was. I'm thinking that since in my bios I did not have a IRQ being automatically set it was causing a conflict after updating the driver.

Ahh. A quick fix would be setting evrything back to their defaults by clearing the cmos. Then all you do is set the main settings to your liking.

Things like IRQ I leave untouched as the bios will set them accordingly. Never had a problem since ;)

Yeah normally I wouldn't mess with it either but I bought my MB and CPU used and I'm guessing the previous owner wasn't to tech savy
