I've never had any issues with the V770 and any i440BX-based motherboards. Which drivers have you been using (i.e. Diamond's or the actual NVIDIA reference drivers)? Please post your motherboard's BIOS settings too, just to be safe (e.g. if the AGP aperture size is set too low or something).

I had a GeForce4 MX card that had the exact same issue though, turns out the card was bad and needed to be replaced.

What type of monitor are you using? Can you get it to boot in safe mode?

V770 has jumpers to enable and disable AGP 4x support. There's a PDF manual that explains them that you should be able to find with a web search. Might want to try verifying those and perhaps even trying them set both ways.

I had a V770 for years in 440BX, ServerWorks II and Athlon MP board - always rock solid. It's still going in one of my machines somewhere (can't remember which one!).

Does it work anywhere other than Windows (ie in Dos / VESA modes, a Linux live cd etc...)

I have tried both Diamond's and NVIDIA reference drivers and it happens with both. I have looked at the manual my card is set to 2x AGP. It worked in DOS, but I didn't try VESA modes there.

Well, the Viper works correctly under OS/2 Warp 4 with the Scitech Drivers. So I have no idea why its not working with Win9x.

I only experienced issues with a Viper V550 on a LX motherboard. Any 3D game would display blurried textures and freeze after a couple of seconds. When I switched to BX, the problem went away.

Are you using the same rig for this?
If not, it could be the motherboard not having sufficient power provided to the AGP slot to supply the Viper 770 of juice. Many early AGP boards had this problem

It's the same exact computer. Also I checked the BIOS and the AGP Aperture is set to 64 MB.

if all else fails: Google Groups. Looks like a compatibility problem.

Well I installed Windows 2000 Professional and the Viper V770 works great. Installed Quake 2 and OpenGL mode is working wonderfully and I'm running the demos in timedemo mode in loops to make sure the card is fine. I did switch sound cards as I had an Ensoniq AudioPCI, which I switched to an ESS Audiodrive 1868, so maybe that was it. I'll have to do a Windows 98 SE reinstall to see if that was the case. I need more CompactFlash cards now!

Increase this size to the maximum possible.

Yeah the Viper is running under Win98SE as well now with the drivers installed. Quake 2 is looking awesome in OpenGL mode. 😀 I think the AudioPCI just didn't like the Viper.

Maybe due to conflicting IRQ? I think it's worth to try both cards with different IRQ settings. You can manage them in the Win9x Device Manager.

It could be, but honestly I don't want to use that card anyways. I just put it in temporarily because the only ATX power supplies I have on hand lack the -5v rail and wasn't sure if my ISA sound cards would work or not. Right now I have an ESS 1868 Audiodrive in it with my DB60XG, but I'm looking into getting another card thats better. Right now I have several sound cards but I'm not happy with them for the games that I want to play. I have:

Sound Blaster 16 CT2830 with hanging note problem and its pretty noisy
2 x ESS Audiodrives, one is terribly noisy, the other isn't as much
Sound Blaster AWE64 CT4520, terrible General MIDI and no daughterboard support, DOS support isn't that great either

So I'll be looking for another card that isn't noisy and has either decent onboard wavetable or a wavetable header.
