I just applied the fix on my 7900gt as well. It works fine once the computer loads the settings, but still scrambles when I first enter windows. How do you set Riva to apply the settings so that it works on boot up? I applied the box to load at startup but still isn't working. Once in windows, it works fine from there on out.

RivaTuner can only react after Windows have logged on, not before. I have that exact same problem as you and that is mainly the reason why I don't use that card anymore! I think that you'll have to get a new bios for your card my friend. What manufacturer is it? XFX, Gainward, Asus or....?
I think that I may need a bios upgrade myself("contacting XFX customer suppport")
My card is an EVGA. I tried it out at home on my HDTV. It sinks so fast that all I get is a split second after the TV locks onto the resolution and you see the zig zags. Then its fine. I can live with that. I was also having the problem where windows 7 wouldn't run the program automatically. It was waiting for me to hit "Ok" to run a non verified windows program. I had to set the user acount settings to the lowest setting. Now it loads without a prompt.

Just curious has anybody made sure that their display driver is installed and their dispaly is listed correctly under device mngr? Smetimes you will get corruption if the generic PnP driver is installed. Fabe
this is the driver i use for the same card you have. It is a WHQL release
Link to nvidia download loc: NVIDIA DRIVERS 190.62 WHQL
I have been using the nvidia driver installed by windows 7, it seems though that there may be a newer version available directly from nvidia as posted, i will try that and let you know how i get on.....
Though the overclocking method previously noted works fine.......
I have had the same with gfoce 5200 but I have update windows and automaticilly installed ... try it
Ive since installed the latest version from the Nvidia website (190.62), rebooted and my screen went all horizontal lines again. Knew though that if i clicked left and enter it would allow Riva tuner to start. Did this and screen went instantly fine. Curious.
Can i make riva tuner start without having to allow it every boot? or is there nvidia software i can set up to perform the same function?
check this out...
Huge Problem with geforce 7900 GT --- horizontal lines
maybe the 7900GT issues should become a sticky...
Hi all, Just thought i'd report back after trying the firmware overclock solution posted above. Its now working great with no problems right from boot. I didnt change the boot settings as my card has stock boot settings which become OC after boot, and as boot was working fine i didnt see the need.
I just increased the core clock from 580 to 582 and the memory clock from 750 to 755 (although nvidia sys info reports 757).
My only problem was i couldnt get NIBITOR to run under windows 7 64 (though i only tried once) so booted into xp to do this.
The link above has good easy to follow instructions and required downloads.
Good Luck!!
Jonny
