I found a computer on the side walk.
Of course, it didn't work.
In fact it's just because of a dead video card, so problem rapidly solved.
Asus P4C800-E mainboard, Pentium 4 2.8 GHZ, Sound Blaster Audigy , 2 Dvd /writers, Zip IDE drive, a junk wifi card with which I never managed to connect to my router, and a Ati 9800 Pro.

So I'd like to save this Ati ...
I know a bit about electronic.
It gets warm, so I assume part of the power supply works. No capacitor looks "strange".
The fan was stucked by rust, but it was laying outside when I got it.

I tried booting with a PCI card, of course definied as primary in the bios, and the computer doesn't give any sign of life when the 9800 is pluggued.
Even no bios "beep".

Are those cards knowns to have issues ?
For now I use an infamous FX5200, but it's the best I have and is a pain 😀
Thanks.

9800s are known to be failure prone, unless you're doing something very basic such as forgetting to plug in the power molex and it doesn't POST at all I wouldn't count on fixing it.

Try cleaning the contacts, either by using a little bit of rubbing alcohol or with a rubber eraser. This has worked for me on many occasions, however 9800s are indeed failure prone unfortunately!

I know that case. Unfortunately I already recycled mine since it was in bad shape otherwise would have grabbed parts for you. Got it part of this lot a little over a year ago. Wasn't crazy about it TBH.

Was it used without the fan? Any broken off ICs, SMDs or cut traces?

I can't tell for sure. When I got it it was outside, under the rain. The fan was totally seized by rust, so I don't think it just happened in one day.
The screws for the fan were rusty too. And what is funny it's the only place I found rust in the whole computer !
I've never seen a fan stucked this way ... I haven't be able to disassemble it 😀
I suppose it's the primary reason of the failure.

I don't see anything bad on the pcb, even with a magnifying glass.

Thanks 😀
But in fact the case is complete, excepted of course where there's the drives. It's in perfect shape, there's no single scratch.
It's not that I love it, but it's not so bad and "period correct".
Even if I don't consider a circa 2003 computer beeing "retro" 😀
What would be nice to have is the panel for the Audigy. Not that I need it, but nice add-on.

This tall tower case is nice !

Maybe there's hope !
After baking in the oven, Linux tried to load the "radeon" module.
Since the primary card is a (strange) Savage 4 Dual screen, it can only be the 9800.
It failed to complete to boot, and the next one doesn't find it.
Nothing in "lspci" .
But it's better I suppose 😀

Progress !
I baked the card, and changed the main capacitors.
When the card is cold, Linux see it, but after a reboot it's already hot and no sign of life. so there are chances there's a bad solder.
Need to reflow correctly ...

Booting with "nomodeset" :
