I'm running XP SP2 and a Voodoo 5 5500 AGP.

When I have the default Microsoft drivers installed, everything works fine.  But when I install Amigamerlin or SFFT, everything crashes.  During the intro I will get lines across the screen like this:

It will either freeze, very rarely XP will kick back in having disabled the video adapter so I can restart, or most often it will BSoD with a 3dfxsv error.

I can still run Windows fine no matter which drivers are installed, and run games like Final Fantasy 7 just fine if it's in software renderer.

I've tried everything I can think of.  I've manually cleared out all the drivers by uninstalling, rebooting into safemode and deleting every dll by hand until Windows could only detect the adapter.  Then I could install a clean set.  I've even tried reinstalling Windows from the ground up.  And every time, these same lines+crashing in all games.

I would just give up and use the Microsoft drivers, but nothing like 3dfx Tools or Vcontrol works with them.  So what's the deal?

- aperson:

I'm sorry but this looks as a Voodoo5 hardware issue. So, can you test your 3dfx card with Amigamerlin or SFFT driver using another platform (other mobo, cpu, RAM, etc...)?

Let me know.

- to all:

Of course, if anyone have any idea, please post it. Thanks a lot for contribution.

Bye bye

Only the one desktop, and I'm only using it because my Alienware broke last week.  I'll probably just plug in an even older Voodoo 3 PCI and see if that works.  It's not like Dungeon Keeper 2 has massive system requirements.

try to install Win98SE or WinME, i had the same Problem with my Voodoo 3 3000, as i Installed Win98SE it runs all fine.
Maybe try another mobo and CPU like Glide said.

Maybe one of the VSA chips is damaged, have yu tried using it in single mode??
