Begin by posting sharp high resolution images of your card. Plenty of people with sharp eyes here, who might spot missing SMD components, corrosion, burned chips, bulging caps, etc, that you've missed

Hey Cga.8086,

To add to what kaputnik said, see if you can get some photos with really good lighting. Natural light works well. If you have to use artificial light, see if you can diffuse it a bit so it isn't causing a spotlight on the board. Take high res photos of the front and back. Try to get a few shots from different angles as well.

Also note that vogons allows image hosting in the threads. If you use the built-in file upload functionality, it tends to work better for accessing/viewing/zooming than something like imgur - which cuts off the in-thread photos depending on how wide your browser window is (or if you are on mobile).

Should i send it to the oven for 10 minutes?

I've seen this work a couple of times and usually only provides a temporary fix. I would recommend doing as the others say and uploading pictures to see if anyone here can spot anything amiss (I'm always surprised at the people here picking up a lot of non-obvious things just from photos) and saving baking for an absolutely last resort measure.

I had a voodoo3 card with a similar problem. I was able to resolve it by reflashing the BIOS.
There is a trick to do it. I forget the exact procedure, but it involved booting up with an AGP card with the voodoo3 in the PCI slot and running the flash software.

If you are testing on a test setup without a case: please hold the card up straight when testing.

It sounds silly maybe but i have tested a couple of v3 pci cards that would not post when sitting loose in the pci slot but when i held it straight up and applied a little pressure they worked fine. Only had this with voodoo's, just like the pcb is a tiny bit thinner (they probably aren't).

At least try cleaning the pci connector. The ''oven trick'' is a waste of time with these cards imho.

Before messing with the board, try this:

Get an eraser, preferably one of the classic ones with a red and blue side. Then use it on the PCI connector on the card. This has worked for me on multiple occasions, I even had a Voodoo5 that wouldn't post and used this neat trick to make it work again.
Sometimes, the contacts become really dirty, which is why this works. Hopefully, it'll fix your Voodoo3 as well 😀.

I have a V3 3000 PCI myself, I can compare to screenshots if you post some.

My V3 PCI gets a little wobbly when not in a case as well. Damn thing has been through a lot of crap though and is still kicking.

Hi guys

here are some high res pics of the card i got
I also wanted to say that i already did the eraser thing, does not work
i also put the card straight, moved a little bit up, moved a little bit down, and no go.

I might try the BIOS reflash? so i have to use an agp card and also the pci card and try to reflash one of the bios found online for the vodoo3 2000 pci sdram

Does capacitor C131 on the right hand side of the front of the board have a good connection? It looks crooked. Could actually be broken internally even if it is attached.

it looks ok, looks curved because someone changed it, it is not the original, so there is more soder below

I think I found the instructions for reflashing (and BIOS images) on that website that was very dedicated to providing 3rd party support for voodoo cards. I can't remember the name, but I believe it may have been shut down (but an archive exists). I believe the flash software was not generic, it was specific to the voodoo3 cards.

Allows to recover misflashed 3dfx Cards

it creates a floppy and asks you to use an agp card to boot.
maybe thats what you used.

I don't know any specific measuring points, but try to find some sign of appropriate voltage(s) coming in and out of the heatsinked regulator, and maybe that 5 pinned component.
If you can find a datasheet for those components you might also get more of an idea of what they should be doing.
SDRAM chips should be getting 3.3v, I don't know what this GPU runs on.
If you're really careful, you can even look for GPU voltage(s) at the tiny SMD ceramic caps near or underneath the GPU. If you try that, insulate the probe so that only it's tip is exposed, so there's less risk of shorting anything. Put the negative probe somewhere easy and safe, like the slide bracket or just use the PSU casing.

Although, if the card shows up when you go to reflash the BIOS, that would imply it's getting power. I don't know how much of the card needs to be powered for the reflash to work.

Don't consider the oven thing unless you're about to throw it away, and even then, I don't know if it ever works on cards of this period.
