Do that after a wash.
It's pretty dirty.

Looked more closely at the pic.
You have tried both DVI ports, yes?
They appear to both be VGA converted by SI chips.
Wouldn't be the first time one was a dud and the other was fine.

Issue occurs on both DVI ports 🙁

ok.
C112 by the back of the connector doesn't look like other empty pads.
Factory or missing?
U819 top left looks odd. I get that its a factory option but it still looks hand soldered.

You did notice the test points... yes?
TP## mostly near the right.
Worth a multimeter on those one by one see if anything stands out.

flux on C1293. yours?

Sorry I'm not sure where this is located on the PCB. Can you give me more hints 😀

Sorry, again I'm not sure where these locations are. I removed C1406, C1552 and C1550 to test caps.

Just above the back of the connector on the front.

They're labelled TP. There are heaps of them. But the ones on the right bear the main caps are the most likely to show voltage drops.

Ahh yes sorry I see them now. I was looking at the DVI connector section.

BUT....I think you're onto something. This card has been recapped previously, ARRRG. Well it's weird. The capacitors are still factory original, but they've been removed and installed back again by hand. I've marked them in green. Maybe someone else found the same issue and tested caps to see if they were bad.

They look clearly hand soldered. When I saw those i thought it was you when testing ESR.

Do you tried VGA (on both ports) ? -> There are no VGA ports

There are, you simply need passive DVI-A to VGA adapter (since ALL ports on your card are DVI-I).

I don't like to use HDMI adapter on GF4, it may not work on boot (black screen/no signal), and/or only work after Nvidia driver kicks in at around Windows loading mark (depends on monitor/capture card).
They are also quite finicky on 1080p support (720p via HDMI works best).

In short : VGA is A LOT better option than HDMI on this old cards (assuming you have VGA capable monitor).

I tested different capacitors. My soldering is not that nasty 🤣

I’m using a DVI cable to connect the card to the DVI port on the monitor. There is no HDMI in the connection.

Ok so next things to try…

1. Wash card
2. Heat card
3. Replace caps
